I think it's time we say goodbye toisn't preparing us for anything. They're using us for money by making us see ads and pay for premium. Instead of actually learning, we use as a crutch. When some of us go back to in real school, we will know nothing. I want to do better, I want you to do better, because we all deserve better, who's with me?

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.)

How does changing the frequency affect the energy of the wave?
