In what direction does the medium move relative to the direction of the wave? explain.

As we can see that the boy is moving his hand up and down while producing the wave in the string.

Here we can see that the source of disturbance or source of wave here in this example is the boy who is holding the string at one end.

So here the motion of the hand of boy is representing the motion of medium molecules in the medium always

So here the disturbance of wave is travelling in the string to the right direction while if we see the direction of medium molecules then it is moving perpendicular to the string i.e. up and down

This type of wave is known as transverse waves in which medium molecules moves perpendicular to the direction of wave

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
