The correct answer from each drop-down menu is thermal energy moves from A to B by conduction the heat transfer will continue until the liquid in B reaches the same temperature as the liquid in A.
What is a heat conductor?Good thermal conductors have an atomic or molecular arrangement that has the property of transferring heat to nearby atoms or molecules until the entire object is in thermal equilibrium. To understand better, let's take a metal bar as an example, which is a good thermal conductor.
In this case, the thermal energy moves from A to B by conduction the heat transfer will continue until the liquid in B reaches the same temperature as the liquid in A.

We can expect the force of friction to be greater for an object moving on a surface if the surfaces in contact are
a) smooth and the object is heavier
b) smooth and the object is lighter
c) rough and the object is heavier
d) rough and the object is lighter
Answer:
c
Explanation:
Friction is caused by how rough and object is, and how much the object weighs, as this causes it to drag more.

A 100 kg object moving at 20 m/s comes to a stop over a distance of 40 m. what is the coefficient of kinetic friction between the object and the ground? (show work please)
Answer:
.5097
Explanation:
Original KE = 1/2 (100)(20)^2 = 20 000 J
the force of friction must work this hard to stop the object in 40 m
Ff *40 = 20 000
Ff = 500 = Fn u u = coeff of kinetic friction
500 = (100)(9.81) u
u = .5097
The kinetic friction coefficient between the object and the ground is 0.5097.
What is kinetic friction?The friction force to normal force ratio experienced by a body moving on a dry, non-smooth surface is denoted by the kinetic friction coefficient k.
Formula :
μk = [tex]\frac{Ff}{Fn}[/tex]
The types and values of the coefficient of friction are determined by the type of resistive force. The coefficient of friction can be determined through experiments such as calculating the amount of power required to overcome friction or calculating the angle at which an object begins to slide off an incline. The kinetic friction coefficient, or k, is the ratio of friction force to normal force felt by a body moving on a dry, uneven surface. Friction can be classified as static, kinetic, deformation, molecular, or rolling. Each one has a different coefficient of friction. Kinetic friction is the force that prevents normal motion after static friction has been overcome.Therefore,
Original KE = 1/2 (100)(20)^2 = 20 000 J
the force of friction must work this hard to stop the object in 40 m
Ff × 40 = 20 000
Ff = 500 = Fnμ μ = coeff of kinetic friction
500 = (100)(9.81) μ
μ = 500/(100 x 9.81)
μ = .5097

The amplitude of the resultant wave when two sound waves with equal amplitude constructively interfere, will be twice than the amplitude of each wave.
What is a constructive interference?
A constructive interference occurs when two sound waves with equal amplitude moving in the same direction collide which each other, forming a single wave (resultant wave) with a higher amplitude.
Thus, we can conclude that the amplitude of the resultant wave when two sound waves with equal amplitude constructively interfere, will be twice than the amplitude of each wave.

A net forward force as well as gravitational force pulls the marble downwards whereas frictional force slows it down.
What is a force?A force is an agent which causes a change in the motion or state of an object.
Forces are of two types:
Contact forces andNon-contact forcesAndrew applies force on the marble causing it to move.
When Andrew pokes the marble, he gives it net forward force. As the marble rolls down the ramp, gravitational force pulls it down.
The movement of the marble is slowed down by frictional force from the ramp.
