Answer:
New force = 9(initial force)
Explanation:
The force between two charges is given by :
Where
d is the original distance
Let d' is the new distance such that, r' = r/3
New force,
So, the new force becomes 9 times the initial force.
Answer:
a = v^2 / R centripetal acceleration
R = v^2 / a a at the surface of earth is 9.8 m/s^2
R = (90 m/s)^2 / 9.8 m/s^2 = 827 m
The waves that are related to both electricity and magnetism are known as (EM) waves .electromagnetic Waves' this line is about a different topic than the rest of Shondra’s notes.
<h3 /><h3>What is an electromagnetic wave?</h3>
The waves that are related to both electricity and magnetism are known as electromagnetic (EM) waves. These waves are made up of time-varying electric and magnetic fields that travel over space.
These waves, which are related to electricity and magnetism, would undoubtedly spread in space. The waves that are related to both electricity and magnetism are known as electromagnetic (EM) waves.

The correct option is D.
During hurricane, the most important thing is to get people out to safety in order to save their lives. Training the community about safety evacuation route is by far the better idea because it provide immediate safety from the natural hazard. The second idea is not a good one at all, because if food are stocked in every house in the community, the food will be destroyed alongside other things during the hurricane.
