Gravitational potential energy.
As the rider falls, the GPE is converted into kinetic energy.
Answer:
First, let's define the coordinate axes: positive x direction is to the right, positive y direction is to upwards, and z direction is out-of-the plane (towards you).
If the particle is moving with velocity in the presence of an external E-field, than according to the below formula E-field pushes the positive charge in the direction of the field, which is upward.
.
If the velocity of the particle is unchanged, this means that the particle does not have an acceleration, so net force applied to the particle is zero.
We know that the force caused by the E-field is upwards, so an equal amount of another force is directed downwards. This second force is caused by magnetic field.
This is the magnitude of the magnetic field.
For the direction of the magnetic field we can use right-hand rule with the following equation:
Here, is in the x-direction. is in the (-y)-direction.
According to the right-hand rule, B-field should be in the z-direction (out-of-the plane, towards you.)

Answer:
the gravitational force between the satellite and the planet is 32.4 * 10³N
Explanation:
It is given that,
Mass of the satellite, m = 6500 kg
Speed of the satellite, v = 6.7 × 10³ m/s
distance to the center of the planet = 9 × 10⁶m
Let F is the magnitude of the gravitational force exerted on the satellite by the planet. The centripetal force is equal to the gravitational force. It is equal to :
= 32.4 * 10³N
the gravitational force between the satellite and the planet is 32.4 * 10³N

A mirror is used to see your own reflection. Earlier in the days, people would use a still water to see their reflection. It is basically used for grooming. Spherical mirrors have been used by earlier mathematicians and physicist to conduct experiments related to geometry. </span>
