The acceleration due to gravity on the moon is about 1/6 of the acceleration due to gravity on the earth. A net force F acts horizontally on an object on the Moon, producing an acceleration equal to am. In the absence of friction and drag, the same force acting on the same object on Earth would produce an acceleration i. e. equal to

a. 6am
b. (1/6)am
c. am
d. 0
e. 9.8 m/s2

c.

Explanation:

We are given that

Acceleration due to gravity on the moon=

Acceleration due to gravity on the earth=

Net force due to am on an object on moon=

There is no friction and no drag force and there is no gravity involved

Then, the force acting on an object on earth=

(given)

Hence, option c is true.

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
