0.095kg is going in a circle on a horizontal frictionless surface. It is held in its orbit by 0.65 s (10%) Problem 1: A puck of mass m = massless string of length L 0.85 m. The puck makes one revolution every t 50% Part (a) What the magnitude of the tension in the string, F, in Newtons, while it spins? 50% Part (b) The string breaks suddenly. How fast does the puck move away, v in m/s?

Why does the input force have to be greater than the force needed to lift the bale?

In a load, the load is paralel to the shaft. n a. angular n b. thrust n c radial n d. none of the above

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
