A 0.040 kg ball tied to a string moves in a circle that has a radius of 0.700 m. The period is 1.5 s. What is the tangential velocity of the ball?

Answer ( slope);

Sounds propagates through some kind of medium. usually it's air, but it goes just as well through solid objects like walls, windows etc. a soundwave will compress the (air)molecules in front of it, and if this increased density wave hits your ears, you register it as sound. solid objects like walls are a lot denser than air, this means that they will damp a wave, but also carry it easier.

A=v^2/r solve for r hope that
