10 points! In a transverse wave, the amplitude shows us..

a. what radio station it is

b. the amount of energy that is created by the wave

c. how far the particles move back and forth.

Observations show that interstellar clouds can have almost any shape and

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
