d. subduction"

Answers

Answer 1

Weathering is the process by which rocks break down in place to produce soils and sediments.

The breakdown or dissolving of rocks and minerals on the earth's surface is known as weathering. Carrier of weathering include water, ice, acids, plants, animals and variations in temperature.

Erosion is the movement of soil, rock, or dissolved material from one region of the earth's crust to another, where it is deposited. Weathering, which is a static process, is distinct from erosion.

Rocks break down by the process called weathering. The effect of weathering and erosion cannot be resisted by any rock on Earth due to its softness.

the change in velocity between location d and location f: select an option unanswered the change in momentum between location d and location f: select an option unanswered the average net force between location

Answers

The change in the momentum is equal to the product of the mass and the change in the velocity.

what is change in momentum?

The change in momentum (Δp ) is defined as the change in the product of an object's mass and velocity. A force is required to change the momentum of an object. This applied force can increase or decrease the momentum or even change the object's direction.

The change in momentum = m × (v – u). Here a = [(v - u)t ] is the acceleration, which is the rate of change of velocity. The quantity, k is a constant of proportionality. The SI units of mass and acceleration are kg and m s-2 respectively.

Δ p = F net Δ t . F net Δ t F net Δ t is known as impulse and this equation is known as the impulse-momentum theorem. From the equation, we see that the impulse equals the average net external force multiplied by the time this force acts. It is equal to the change in momentum.

Sally, Max, and William are on a camping trip in the forest. They are riding their bikes through the forest and come across a clearing. In the clearing, there are several trees and a small plane. Sally is curious about the physics of the plane, so she asks Max and William to help her measure the distance from the plane to the nearest tree. They use a measuring tape to find that the distance is 60 meters. They also measure the height of the plane to be 10 meters and the height of the tree to be 20 meters. Using the principles of physics, they calculate the angle at which the plane is flying relative to the tree. What is the angle?

Answers

Answer: The angle at which the plane is flying relative to the tree is 19.47 degrees.

Explanation:

To calculate the angle at which the plane is flying relative to the tree, we can use the principle of trigonometry and the Pythagorean theorem. Since we know the distance from the plane to the nearest tree (60 meters), the height of the plane (10 meters), and the height of the tree (20 meters), we can use these measurements to form a right triangle with the plane, the tree, and the ground.

Using the Pythagorean theorem, we can calculate the length of the hypotenuse of the right triangle. The length of the hypotenuse is the distance between the plane and the top of the tree. The hypotenuse is calculated by the square root of (distance^2 + height of the plane^2 + height of the tree^2)

The angle we are trying to calculate is opposite to the height of the tree, therefore we can use the tangent function:

tan(angle) = opposite/adjacent

opposite = height of the tree = 20m

adjacent = distance = 60m

angle = arctan(20/60) = arctan(1/3) = 19.47122063449069 degrees

The angle at which the plane is flying relative to the tree is 19.47 degrees.

Answers

When the accumulation of snow and ice during the winter months exceeds the ice melt during the summer months, the mass of a glacier increases.

How the mass of glacier increases?As summer temperatures rise, the higher glaciers melt to provide water later in the season.If the rate of melting across the glacier increases, the glacier will have a negative mass balance and shrink. If the glacier receives more snow or ice but the amount of melt remains constant, the glacier will expand.Glaciers gain and lose mass due to snowfall and melting and sublimation (when water evaporates directly from solid ice). Glaciers that end in a lake or the ocean lose mass due to iceberg calving.Increased marginal ablation (largely a function of summer temperature for land-based glaciers) overwhelms the mass supplied during climate warming, forcing a glacier margin to retreat.

The remaining particle has a positive charge, q3 = 8.0nC . What is the net electric force acting on particle 3 due to particle 1 and particle 2?
1. Find the net force ?F? 3 acting on particle 3 due to the presence of the other two particles. Report you answer as a magnitude ?F3 and a direction ? measured from the positive x axis. Express the magnitude in newtons and the direction in degrees to three significant figures
2. Assume that particle 3 is no longer fixed to a corner of the triangle and is now allowed to move. In whatdirection would particle 3 move the instant after being released? Draw the velocity vector for particle 3 below. The orientation of your vector will be graded, but not its length

Answers

1. The net force is 79.1°

The angle between those two forces is 120 degrees (because the triangle is equilateral) so the net force on particle 3 is the vector sum of the two forces.

The direction of the force on particle 3 due to particle 1 is along the line joining particles 1 and 3. The direction of the force on particle 3 due to particle 2 is along the line joining particles 2 and 3.

To find the net electric force acting on particle 3 due to particles 1 and 2, we can use Coulomb's law, which states that the force between two point charges is given by the equation:

[tex]F = k * (q1 * q2) / r^2[/tex]

where F is the force, k is the Coulomb constant [tex](8.99 x 10^9 N * m^2/C^2)[/tex], q1 and q2 are the charges of the two particles, and r is the distance between the two particles.

In this case, we have three particles placed at the corners of an equilateral triangle, with a side length of 3.1 cm. Since the triangle is equilateral, all three sides are equal in length, so r1 = r2 = 3.1 cm

The net force on particle 3 is the vector sum of the two forces acting on it due to particles 1 and 2.

F3 = F31 + F32 where F31 is the force on particle 3 due to particle 1 and F32 is the force on particle 3 due to particle 2

[tex]F31 = k * (q3 * q1) / r1^2[/tex]

[tex]F32 = k * (q3 * q2) / r2^2[/tex]

[tex]F31 = 8.99 x 10^9 N * m^2/C^2 * (8.0 nC * -8.4 nC) / (3.1 cm)^2[/tex]

[tex]F32 = 8.99 x 10^9 N * m^2/C^2 * (8.0 nC * -16.8 nC) / (3.1 cm)^2[/tex]

[tex]F31 = -9.52 * 10^{-4 N}[/tex]

[tex]F32 = -1.93 * 10^{-3 N}[/tex]

[tex]F3 = F31 + F32 = -2.88 * 10^{-3 N}[/tex]

After solving, The net force = 79.1°

The direction of the force on particle 3 due to particle 1 is along the line joining particles 1 and 3. The direction of the force on particle 3 due to particle 2 is along the line joining particles 2 and 3.

The angle between those two forces is 120 degrees (because the triangle is equilateral) so the net force on particle 3 is the vector sum of the two forces

2. Particle 3 will move in the direction of the net force acting on it, which is the vector sum of the two forces acting on it due to particles 1 and 2.

Since the net force is [tex]-2.88 * 10^{-3 N}[/tex], and the angle between the direction of the forces on particle 3 due to particles 1 and 2 is 120 degrees, particle 3 will move in the direction of the angle bisector of the angle between those two forces.

The angle bisector of 120 degrees is 60 degrees, thus the net force is acting on particle 3 at 60 degrees with respect to the positive x-axis.

The instant after being released, particle 3 will move in the direction of the net force vector and it will have a velocity vector pointing in the same direction as the net force.

Required:
What is the magnitude of the charge (in nC) on each bead?

Answers

The magnitude of the charge on each bead is 7.08nc.

What is the magnitude of charge?

Given the following information:

Original length = 4.0 cm converted to m = 0.04 m

1.4 grams to kilograms = 0.0014

5.1 cm to m = 0.051 is the new length.

4.6 cm to m = 0.046 m is the final length.

e =  0.051 - 0.046

= 0.005m in length

Scientific evidence:

Gravitational acceleration = 9.8m/s²

Coulomb's constant is equal to 8.99 x 10⁹ Nm²/C²

We would use Coulomb's law to calculate the magnitude of the charge (in nC) on each bead:

First, we would calculate the spring constant of this lightweight spring

using the following formula:

W = mg = Ke

K = mg/e

K = 0.014 x 9.8 / 0.05

K = 2.744N/m

K, the spring constant, is 2.744N/m.

In terms of electrostatic force:

F = ke

F = 2.77 x 0.05

F = 0.1385

F equals 0.1385 Newton.

Coulomb's electrostatic force law.

The charge in an electric field can be calculated mathematically using the following formula:

q = √F/k x r

We get by substituting the given parameters into the formula;

q = √(0.1385/8.99 x 10⁹) x 0.046

q = √(1.54060 x 10⁻¹²) x 0.046

the support bearings at a and b allow free turning of the shaft. (figure 1) figure1 of 1 part a determine the resultant internal torque acting on the cross section at points c and d . enter your answers in newton-meters to three significant figures separated by a comma.

Answers

The internal torque acting at point C is 800 lb-ft clockwise, and at point D is  1500 ft-lb anti-clockwise.

The shaft is bearing at a and b. As the shaft is at rest and not rotating in any direction. So the internal torque must be balancing the external torques acting on the shaft. Near the bearing A, the the external torque acting on the shaft is 1500 lb-ft clockwise, so at point D there must be an anti-clockwise torque. So the torque acting on the D is 1500 ft-lb.

Similarly, near the bearing B the external torque acting on the shaft is 800 lb-ft anti-clockwise, so there must be an equal and external clockwise torque working on point C to balance the 800 anti-clockwise torque. So the internal torque working on point C is 800 lb-ft.

a softball is thrown off of a building that is 80 meters high at a velocity of 10 meters per second. its height, in meters, after t seconds is

Answers

When a softball is thrown from an 80-meter-high building at a velocity of 10 meters per second, the height after t seconds is 148 feet.

What is velocity?

Velocity is a vector representation of an object's or particle's displacement with respect to time. The meter per second (m/s) is the standard unit of velocity magnitude (also known as speed). Alternatively, velocity magnitude can be expressed in centimeters per second (cm/s). The direction of movement of the body or item is defined by velocity. Speed is fundamentally a scalar number. Velocity is, in essence, a vector quantity. It is the pace at which distance changes. It is the displacement rate of change. Speed is the pace at which an item moves along a route in time, whereas velocity is the rate and direction of movement. In other words, velocity is a vector, whereas speed is a scalar number.

Here,

The maximum height the ball will reach is the vertex of the parabola s(t)=48+80t-16t2. first, we need to solve for t. The vertex of any parabola of the form f(x)=ax2+bx+c is found by using x=-b/2a. In this case, x=t, b=80 and a=-16. Substituting we get:

]t=-80/((2)(-16)--->t=-80/-32--->t=5/2

Putting this value of t in the original formula will give us the maximum height:

s(t)=48+80t-16t2

s(5/2)=48+80(5/2)-16(5/2)2

s(5/2)=48+200-16(25/4)

s(5/2)=248-100

smax=148 feet

It's height, in meters, after t seconds is 148 feet when softball is thrown off of a building that is 80 meters high at a velocity of 10 meters per second.

What is the spring constant?

We know that in the question, we have been told that A 3.0 g spider is dangling at the end of a silk thread. You soon discover that you can give the spider the largest amplitude on his little bungee cord if you tap exactly once every second.

Thus using;

T = 2π√m/k

m = mass of the spider

k = spring constant

T = time in seconds

Then;

1 = 2 * 3.142√3 * 10^-3/K

1/2 * 3.142 = √3 * 10^-3/K

If you could drive a Jetson's flying car at a constant speed of 160km/hr (100 mi/hr) across oceans and space, approximately how long would it take to drive around Earth's equator?

Answers

If one could drive a Jetson's flying car at a constant speed of 160km/hr (100 mi/hr), the time it will take to drive around the Earth's equator is 250.47hours.

How to calculate time?

The time it will take to cover a certain distance can be calculated using the following formula;

Speed = distance ÷ time

According to this question, one could drive a Jetson's flying car at a constant speed of 160km/hr (100 mi/hr) across oceans and space. The distance around Earth at the Equator, its circumference, is 40,075 kilometers (24,901 miles).

Time = Distance ÷ speed

Time = 40,075km ÷ 160km/hr

Time = 250.47hours

Therefore, 250.47hours is the time it will take to cover around the Earth's equator.

A pulley system has a mechanical advantage of 3, and an object weighing 9 Newtons must be lifted 15
meters. How much force must be applied to lift the object?
Use the following equation to find the answer.
MA= Fo/F i
(1 point)
A. 1.7 N
b. 0.3 N
c.27 N
d.3N

Answers

C. 27 N force must be applied to lift the object.

How much force must be applied to lift the object?The mechanical advantage of a pulley system is calculated by dividing the output force by the input force. In this case, the mechanical advantage is 3, meaning the output force is 3 times larger than the input force.To find the force required to lift the object, we can use the equation: Force = (Weight of Object x Distance) / Mechanical Advantage.Plugging in the given numbers, the force required to lift the object is (9 Newtons x 15 meters) / 3 = 45 Newtons. Therefore, 45 Newtons of force must be applied to lift the object. Using a pulley system to lift an object is advantageous because it reduces the amount of force needed to lift the object. The mechanical advantage of the pulley system multiplies the output force, allowing the user to lift the object with less effort.Pulley systems are often used to lift large or heavy objects, such as in cranes and construction sites.They are also useful in machines and everyday items, such as roller blinds and bicycles.

Figure 9-53 shows an approximate plot of force magnitude F versus time t during the collision of a 58g Superball with a wall. The initial velocity of the ball is 34m/s perpendicular to the wall; the ball rebounds directly back with approximately the same speed, also perpendicular to the wall. What is F max,the maximum magnitude of the force on the ball from the wall during the collision?

Answers

The force applied by the ball on the wall is 3.994 Newton, if the mass of the ball is 58 gm, and initial velocity is 34 m/s.

Mass of the ball, m = 58 gm = 0.058 kg

Initial velocity of the ball, u = +34 m/s

Time of the applied force, t = 1 sec

Final velocity of the ball, after collision, v = -34 m/s  [negative: as the direction is opposite]

Let the force applied by the ball on the wall is F. We know the rate of change of momentum of an object is equal to the force applied by the object. So,

F = (m₁v₁ - m₂v₂)/t

F = (0.058 × 34 - 0.058(-34))

F = 3.944 N

D Exert a force of magnitude 2F on an object of mass m for a time t = 2T. E Exert a force of magnitude 2F on an object of mass m for a time t = .

Answers

Option D: Apply a force of magnitude 2F for a period of time t=2T to a mass m object. The impulse will rise as the force, the passage of time, or the object's mass increase.

The force times the length of time that the force is applied to an item results in the impulse. For a force to impose an impulse on an item, both the force applied and the time period during which it is applied must be non-zero. The scenario in which a force of magnitude 2F is applied to an item of mass m over a period of time t = 2T results in option D being the right response. This is so that, since the impulse is computed as the product of force and time, the impulse will not change if the force and time are both doubled. Alternatives like A, B, and C wouldn't cause an impulse to be applied to an object.

What is the search for fractionally charged particles?

Theoretically, every charge must be a multiple of the charge of an elementary particle or an electron.

Similar automated equipment to that of Millikan and Fletcher was employed. No droplet with a fractional charge was discovered.
