Deposition

Explanation:

The deposition phenomenon happens when sediment created by weathering and moved by erosion settles in a different location due to gravity

Deposition occurs when sediment, a combination of soil and rock produced by weathering, is eroded and transported to a new area.

Deposition is the act of depositing silt that has been transported by the wind, water, sea, or ice.

Earthen materials are worn away during erosion, a geological process in which they are moved by wind or water.

The removal of soil, rock, or dissolved material from one area on the Earth's crust and subsequent transport to another region for deposition are known as erosional processes. Erosion differs from weathering, which is a static process.

Given data ,

Let the sediment be deposited in an another location due to gravity

Now , As sediment, a mixture of soil and rock created by weathering, is eroded and moved to a new region, deposition takes place.

During three interrelated processes, lithification converts loose sediment grains that are produced by weathering and transported by erosion into clastic sedimentary rock. Deposition occurs when gravity and friction work against the forces that move sediment, enabling it to build up.

Hence , when sediment created by weathering and moved by erosion settles in a different location due to gravity , deposition takes place

Explanation:

Answer:

a = 4 m/s²

Explanation:

Given: 5000 g, 20N  

To find: Acceleration (a)  

Solution: Firstly, convert 5000g to kilograms

1000g = 1kg

∴ 5000g = 5kg if divided by 1000

A = F ÷ m

=  20 ÷  5  

= 4 m/s²

Newtons are derived units, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared.

Answer:

"Scientist use radioactive decay to measure the age of a rock or fossil."

Explanation:

"To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events."

Answer:

The height of the water column = 1.62405[tex]\overline{30}[/tex] × 10⁻¹ m

Explanation:

The air cavity in the Coke bottle = 0.220 m deep

The fundamental (frequency) it plays when water is added to shorten the column and it is blown across the top, f = 528 Hz

The given speed of sound in air, v = 343 m/s

We note that the air cavity in the coke bottle is equivalent to a tube closed at one end

The fundamental frequency for a tube closed at one end, 'f', is given as follows;

f = v/(4·L) = v/λ

Where;

L = The height of the water column

λ = The wavelength of the wave

∴ 4·L = v/f = (343 m/s)/(528 Hz) = 0.6496[tex]\overline{21}[/tex] m

∴ L = 0.6496[tex]\overline{21}[/tex] m/4 = 0.162405[tex]\overline{30}[/tex] m

The height of the water column = 1.62405[tex]\overline{30}[/tex] × 10⁻¹ m.

Explanation:

The information tells you about the rate of decay is that in Florida the reaction occurs more slowly when there is less oxygen in the air.

The reduction in the number of radionuclides per unit time is the rate of decay.

The following table shows that the rate of decay only depends upon the level of oxygen. In Florida concentration of the oxygen in the air is high

Due to this the decay time is less.

The decay time is inversly propotional to the rate of decay. In Florida the rate of decay is high.

Hence the information is that reaction occurs more slowly when there is less oxygen in the air.

Answer:

the kinetic energy decrease is equal to potential energy increase

If the potential energy of pendulum increases then the kinetic energy decreases and if the kinetic energy increases then the potential energy decreases.

According to the work power theorem the total energy of any object will remain constant like the sum of the kinetic and the potential energy of the object will remain constant.

The potential energy of any object is due to its position with respect to the ground. If the object is at a height of H then it will have a potential energy because some energy is given to that object against the gravity to move it to the height H.

The kinetic energy is the energy due to the velocity of the object and is given as the product of half mass to the velocity square.

Now we will express it in the form of the formula for better understanding .

[tex]\rm Total\ energy= KE+PE[/tex]

Now in the pendulum the motion is back and forth with respect to its mean position. So the total energy in the pendulum is the sum of the kinetic energy and the potential energy.

Now if the pendulum attains the maximum displacement from its mean position then it will have maximum potential energy and zero kinetic energy at this point.

Now if the pendulum is at the mean position now it will have maximum kinetic energy and zero potential energy at this point.At this point the potential energy totally converted to the kinetic energy.

Now at the maximum displacement the kinetic energy totally converts into the potential energy of the pendulum.

Thus If the potential energy of pendulum increases then the kinetic energy decreases and if the kinetic energy increases then the potential energy decreases.

Answer:

Liquid

Explanation:

Before anything evaporates, it is in a liquid state.

Answer:

0.832 m/s

Explanation:

The work done by the spring W equals the kinetic energy of the object K

The work done by the spring W = 1/2k(x₀² - x₁²) where k = spring constant, x₀   = initial compression = 0.065 m and x₁ = final compression = 0.032 m

The kinetic energy of the object, K = 1/2mv² where m = mass of object and v = speed of object

Since W = K,

1/2k(x₀² - x₁²) = 1/2mv²

k(x₀² - x₁²) = mv²

mv² = k(x₀² - x₁²)

v² = [(k/m)(x₀² - x₁²)]

taking square root of both sides, we have

v = √[(k/m)(x₀² - x₁²)] since ω = angular frequency = √(k/m),

v = √[(k/m)√(x₀² - x₁²)]

v = ω√(x₀² - x₁²)]

Since ω = 14.7 rad/s, we substitute the other variables into the equation, so we have

v = 14.7 rad/s × √((0.065 m)² - (0.032 m)²)]

v = 14.7 rad/s × √(0.004225 m² - 0.001024 m²)]

v = 14.7 rad/s × √(0.003201 m²)

v = 14.7 rad/s × 0.056577

v = 0.832 m/s

Answer:

770.1 m

Explanation:

From the question given above, the following data were obtained:

Velocity (v) = 45.3 m/s

Time (t) = 17 s

Displacement (d) =?

Velocity is defined according to the following formula:

Velocity = Displacement /Time

With the above formula, we can obtain the displacement of the ball as follow:

Velocity = Displacement /Time

45.3 = Displacement / 17

Cross multiply

Displacement = 45.3 × 17

Displacement = 770.1 m

Therefore the displacement of the ball is 770.1 m

You are 100% right for question a and you have a good start on b!

Explanation:

For (ii) of part a, you could also say that since the friction force is in the opposite direction of the pushing force, that the friction is '-60N' The negative sign just shows the direction of friction relative to the pushing force. But for the magnitude the signs are not important.

For part b,

work done equals force × distance

w = F×d

In this case, the worker is pushing with 60 newtons, and the distance is 28m.

Therefore,

w = 60N×28m

w = 1680j

(Or 1.7kj)
