Asolid ball mass=1kg and radius=.10m rolls down a ramp(with friction) and goes through the loop.
a) what is “h” if the ball is on the verge of leaving the track when ut reaches the top of the loop?
b) what is ‘h’ if the ball on the verge of leaving the track when it reaches the top of the loop is hollow?

What is a carrier wave and how does it affect what you hear on the radio

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
