A trolley is pushed with a force that causes it to move a certain distance. It moves in the
direction it is pushed
Which row in the table represents the combination of force and distance that means the
smallest amount of work is done on the trolley?

Answer:

This transformer would be a step-up transformer.

Explanation:

In a transformer, the primary coil is connected to the AC input while the secondary coil is connected to the AC output.

Let [tex]V_P[/tex] and [tex]N_P[/tex] denote the primary voltage (at the input) and number of turns in the primary coil.

Let [tex]V_S[/tex] and [tex]N_S[/tex] denote the secondary voltage (at the output) and the number of turns in the secondary coil.

Ideally, the voltage in each coil would proportional to the number of turns in that coil:

[tex]\displaystyle \frac{V_S}{V_P} = \frac{N_S}{N_P}[/tex].

For example, in this question, [tex]N_P = 100[/tex] (primary coil, connected to the AC input) whereas [tex]N_S = 150[/tex] (secondary coil, connected to the AC output.)

[tex]N_S = 1.5 \, N_P[/tex]. Accordingly, the voltage in the secondary coil (AC output) would be approximately [tex]1.5[/tex] times the voltage in the primary coil (AC input): [tex]V_S = 1.5\, V_P[/tex].

Hence, the secondary voltage of this transformer (AC output) would exceed the primary voltage (AC input.) This transformer would be a step-up transformer.

From the wording of the question, I'm suspecting that you have ...

... either a piece of equipment or else a computer program named "myDAQ",

... an inductor to play with and measure, either in your hand or on the screen.

I have none of these advantages.

In fact, nobody reading this on Brainly has.

It's like if I asked you to write an equation that can be solved to find the total amount of money in all five of my pockets right now.    

Answer:

Power

Explanation:

Answer:

Rip currents often form near structures in the water such as piers or jetties, when wave heights change suddenly, or most frequently when a channel is cut into a sandbar

Answer:

Resistance, R = 60 Ohms

Explanation:

Given the following data;

For the first heater;

Voltage, V = 120 V

Resistance, R = 15 Ohms

For the second heater;

Voltage, V = 240 V

To find the resistance in the second heater;

First of all, we would determine the power rating of the heaters using the formula below;

Power = voltage²/resistance

Power = 120²/15

Power = 14400/15

Power = 960 Watts

Next, we find the resistance in the second heater;

Power = V²/R

960 = 240²/R

Cross-multiplying, we have;

960R = 57600

R = 57600/960

R = 60 Ohms

They're always expressed.

Solution :

Mass of the particle = M

Speed of travel = v

Energy of one photon after the decay which moves in the positive x direction = 233 MeV

Energy of second photon after the decay which moves in the negative x direction = 21 MeV

Therefore, the total energy after the decay is = 233 + 21

                                                                           = 254 MeV

So by the law of conservation of energy, we have :

Total energy before the decay = total energy after decay

So, the total relativistic energy of the particle before its decay = 254 MeV  

Answer:

1.2

Explanation:

4/100 × 30= 1.2

when we placed in the container of real depth assuming = d

if the container filled with liquid A then its apparent depth d' = 7cm

so the refractive index nA = real depth / apparent depth

                                       = d/7cm = 0.1428d

if the container filled with liquid B then its apparent depth d' = 6cm

so the refractive index nB = real depth / apparent depth

                                       = d/6cm = 0.166d

if the container filled with liquid C then its apparent depth d' = 5cm

so the refractive index nC = real depth / apparent depth

                                       = d/5cm = 0.2d

Since the refractive index is inversely proportional to the apparent depth

then the refractive indices are nC > nB > nA

Answer:

F = 350 N

Explanation:

Force Equation

F=ma

Newton's second law states that force is proportional to what is required for an object of constant mass to change its velocity. This is equal to that object's mass multiplied by its acceleration. We use Newtons, kilograms, and meters per second squared as our default units, although any appropriate units for mass (grams, ounces, etc.) or velocity (miles per hour per second, millimeters per second2, etc.) could certainly be used as well - the calculation is the same regardless.

How to solve

Formula: FNet = Fa + Fg.

F = m * a

F = 70.0 kg × 5.00 m/s2

F = 350 N

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:

I just know that the first one is b

Explanation:

The principle of cross-cutting relationships states that a fault or intrusion is younger than the rocks that it cuts through. The fault labeled "E" cuts through all three sedimentary rock layers (A, B,and C) and also cuts through the intrusion (D). So the fault must be the youngest formation that is seen and known of.

The age of the fault A is in between rock B and intrusion D. Hence A is the youngest rock and C be the oldest rock here.

A fault is a crack or region of cracks that separates two rock blocks. The blocks might move in relation to one another due to flaws. This movement may happen suddenly, like an earthquake, or it may happen gradually, like creep.

From a few millimeters to thousands of kilometers, faults can vary in length. Over geologic time, most faults cause recurrent displacements. The rock on one side of the fault abruptly shifts in relation to the other during an earthquake. The fault surface may be vertical, horizontal, or at any other arbitrary angle.

The principal of superposition states that, the oldest layer will be the bottom of the young rocks. Here, rock is A is above B and C. Hence, rock A is youngest than layer B and C.

Answer:

vf = 9.48 m/s

Explanation:

From the law of conservation of energy we can write:

[tex]Kinetic\ Energy\ Lost = Work\ Against\ Friction\\\frac{1}{2}m(v_i^2 - v_f^2) = fd\\\frac{1}{2}m(v_i^2 - v_f^2) = (\mu W)d\\\frac{1}{2}m(v_i^2 - v_f^2) = (\mu mg)d\\\frac{1}{2}(v_i^2 - v_f^2) = \mu gd\\v_f^2 = v_i^2 - 2\mu gd[/tex]

where,

vf = final speed = ?

vi = initial speed = 10.1 m/s

μ = coefficient of friction = 0.3

g = acceleration due to gravity = 9.81 m/s²

d = distance covered = 2.07 m

Therefore,

[tex]v_f^2 = (10.1\ m/s)^2 - 2(0.3)(9.81\ m/s^2)(2.07\ m)\\v_f^2 = 102.01\ m^2/s^2 - 12.18\ m^2/s^2\\v_f = \sqrt{89.83\ m^2/s^2}\\[/tex]

vf = 9.48 m/s

Answer:

At that time, she was in the southern hemisphere

Explanation:

She is witnessing the southeastern trade breeze because the cloud is passing from east to west and she is also witnessing a storm from the southeast.

Because of the Coriolis effect, which deviates the atmosphere in the left-hand side of the southern hemisphere and generates a southeastern wind, this wind did not blow directly from south to east.

The gradient here represents Angela's Velocity.

Explanation:

A distance-time graph has distance on its y-axis and time on its x-axis. Therefore, the gradient of the distance-time graph is given by the following formula:

[tex]Gradient = \frac{Change\ on\ y-axis}{Change\ on\ x-axis} \\\\Gradient = \frac{Distance\ Covered\ by\ Angela}{Time\ taken\ to\ cover\ the\ distance}\\\\Gradient = Angela's\ Velocity[/tex]

Since the rate of change of distance is called the velocity.

Therefore, the gradient here represents Angela's Velocity.

The force between the two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Hence, if distance between charges is halved (charges remaining kept constant), the force between the two charges is quadrupled.

Explanation:

Answer:

The wave moves with a velocity of 37.5 m/s

Explanation:

We know that the speed of a wave is given by:

V = f*λ

Where f is the frequency (the inverse of the period)

Then:

f = 1/T

And we know that T = 2 s/cycle

f = 1/(2 s/cycle) = (1/2) cycle/s

And λ is the wavelength, we know that:

λ = 75m/cycle.

Then the speed of the wave is:

v = ( (1/2) cycle/s)*(75m/cycle) = (75/2) m/s = 37.5 m/s
