Electric current is a stream of electrons in motion, so they have to gain an energy from outside. There are two possibilities: one of them is the photoeletric phenomenom which is based on striking electrons from their orbits with the photon's energy. Second options is the substraction od eletric potentials on the edges od material.
Answer:
19.48 m
Explanation:
Gravitational potential energy = mgh
Current weight = 539 N
Weight = mg = 539 N
Mass x Acceleration = 539 N
Mass x 9.81 = 539
Mass = 54.94 kg
Gravitational potential energy = mgh = 10500 J
54.94 x 9.81 x h = 10500
h = 19.48 m
Height of sitting = 19.48 m
Answer:
the is D
Explanation:
An action-reaction force pair
I really don’t know but I hope this helps
Tension pointing up at the top
Weight pointing down at the bottom
If there is someone standing inside the elevator, there will be a normal reaction force pointing down at the bottom.
