Why does a raindrop accelerate as it falls to the earth? a) because it gains mass during its travel b) because the force of gravity pulls on the drop c) because it gets further from the cloud where it started d) because fewer forces are present to slow it down as it drops

the correct answer is b

The correct answer is B.

Explanation:

A raindrop accelerates as it falls to the earth.

In a freely falling condition, only the force of gravity will act on the drop. There is a force attraction between the earth and the drop. The acceleration due to gravity will act in this case.

A raindrop accelerates as it falls to the earth because the force of gravity pulls on the drop.

Therefore, the correct option id B.

i don't understand. explain it clearly

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
