Two objects, x and y, move toward one another and eventually collide. object x has a mass of 2m and is moving at a speed of 2vo to the right before the collision. object y has a mass of m and is moving at a speed of vo to the left before the collision. which of the following describes the magnitude of the forces f the objects exert on each other when they collide?

a. the force exerted by x on y is 4f to the right, and the force exerted by y on x is f to the left.
b. the force exerted by x on y is 2f to the right, and the force exerted by y on x is f to the left.
c. the force exerted by x on y is f to the right, and the force exerted by yon x is f to the left.
d. the force exerted by x on y is f to the left, and the force exerted by y on x is f to the right.

The force exerted by X on Y is F to the right, and the force exerted by Yon X is F to the left.

Explanation:

There are two objects X and Y. Mass of object X is 2M, that is moving with a speed of and that of object Y is M that is moving with a speed of .

When both of the objects collide, the magnitude of the forces F the objects exert on each other is equal to :

The force exerted by X on Y is F to the right, and the force exerted by Yon X is F to the left using Newton's third law of motion. Hence, the correct option is (c).

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
