Answer:
Explanation:
An object falling loses gravitational potential energy and gains kinetic energy. The gravity potential is the gravitational potential energy per unit mass. This energy comes from the gravitational potential energy released when the water falls. ... At 0, all the energy is in gravitational potential energy.
Answer:
The direction of the displacement is in North-West.
Explanation:
Resultant displacement D is
Here the direction is

Then the direction is
North-west.
Answer:
10,000 eV
Explanation:
According to the law of conservation of energy, the kinetic energy gained by the electron is equal to its change in electric potential energy:

where:
K is the kinetic energy of the electron
is the magnitude of the charge of the electron
is the potential difference through which the electron has been accelerated
For this electron in the TV, we have

Therefore, the kinetic energy of the electron in electronvolts is
