A boy has climbed to the top of a 6.00-m-tall tree. When he shouts, the sound waves have an intensity of at a 1.00 m distance from the top of the tree. The ratio of intensity at the base of the tree to the intensity 1.00 m from the top of the tree is:

What’s #16 asking and how do i solve it?

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)

Four friends, a, b, c, and d are standing varying distances away from a speaker which is producing sound waves.
