What is the force of gravity (in newtons) acting between the sun and a 4,500-kg rocket that is 0.75 au from the sun?

47.0 N

Explanation:

First of all, let's convert the distance of the rocket from the Sun from AU to metres:

The force of gravity acting between the Sun and the rocket is:

where

is the gravitational constant

is the mass of the Sun

m = 4500 kg is the mass of the rocket

r is the distance between the Sun and the rocket

Substituting into the equation,

false br

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
