Answer:
Moving electrons by cringing the object near another charged object ... This means that there is a different number of protons and electrons ... the attraction or repulsive electrostatic force between positive and negative charges ... the amount of charge on the particle and the distance between the particles ... fixed in position.ation:
Explanation:
a. The force acting down is gravity, on Earth gravity is 10 m/s^2. When the skydiver jump, the acceleration will start out as -10 m/s^2, but it will eventually equals the air resistance , which is called terminal velocity.
Answer:
due to the properties of radioactive elements like penetration power and ionization effect they can cause gene mutations, kill living cells and cause cancer. They also have the advantages. They are used to make nuclear energy

Explanation:
Here is a link to a video to tell you about this.
Speed of light is given as

time interval is given as

so the distance covered by the light is given as


now as we know that

so the distance moved by light is

now for the comparision of this distance with diameter of earth
as we know that radius of earth is

so the diameter of earth will be

now the ratio of diameter with the distance that light move will be


<em>so it is 2.35 times more than the diameter of earth</em>
