Sound waves travel through the air, liquids, and solids. they transfer energy from the source of the sound to its surroundings
Thunder is evidence of electric fields in the atmosphere.
The charge difference between the clouds and earth can be described as parallel conducting plates that produce electric fields in the atmosphere.
could be true
Answer:
B.Ionizing radiation is the correct answer.
Explanation:
Ionizing radiation has sufficient energy that it can convert atoms and molecules into ions.
It has a sufficient amount of energy that it can separate tightly confined electrons from the orbit of an atom and causing that atom to become ionized.
Answer:
c) 
Explanation:
Coulomb's law says that the force exerted between two charges is inversely proportional to the square of distance between them, and is given by the expression:
where k is a proportionality constant with the value 
In this case 
, so we have:
Solving the equation for q, we have:
Replacing the given values:
