8. The mass of the sun is 1.99 x 1030 kilograms and its distance from Earth is 150 million kilometers (150 x 109 meters). What is the gravitational force between the sun and Earth? please help

Explanation:

Given that,

Mass of the Sun,

The distance of Sun from the Earth,

We know that,

The mass of the Earth,

We need to find the gravitational force between the Sun and the Earth.

The formula between two masses is given by :

So, the gravitational force between the Sun and the Earth is

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.

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
