PLEASE HELP! Electric potential depends on which factors?

A: Mass and amount of charge

B: Distance and amount of charge

C: Mass and distance

D: Density and amount of charge

Identify the theory that can be used to explain each phenomenon. answers diffraction: wave theory interference: wave theory reflection: both particle and wave theories refraction: both particle and wave theories

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?
