A newly discovered planet has the same mass as the Earth, but a person standing on the surface of the planet experiences a force

Dafna11 [192]

This question deals with the acceleration due to gravity on the surface of the planet. The value of the acceleration due to gravity on the surface of two planets, that is Earth and on the surface of another planet are compared to find out the relation between the radii of both planets, provided their masses are the same.

The correct option for the radius of the new planet is "Option 3: Square Root of 3 R"

The value of the acceleration due to gravity on the surface of a planet is given by the following formula:

$g = \frac{GM}{R^2}$ ----------- eqn(1)

where,

g = acceleration due to gravity on Earth

G = Universal Gravitational Constant

M = mass of the Earth

R = Radius of the Earth

Now, the same formula for the acceleration due to gravity on the surface of the other planet can be written as follows:

$g' = \frac{GM'}{R'}\\\\$ ------------- eqn(2)

where,

g' = acceleration due to gravity on the new planet

G = Universal Gravitational Constant

M' = mass of the new planet

R' = Radius of the new planet

According to the given condition, the new planet has the same mass as the Earth's mass but the acceleration due to gravity on the surface of the new planet is one-third of the acceleration due to gravity on the surface of Earth.

$M'=M\\\\g'=\frac{1}{3}g$

using eqn (1) and eqn (2):

$\frac{GM}{R'^2}=\frac{1}{3}\frac{GM}{R^2}\\\\R'^2=3R^2\\\\R' = \sqrt{3}R$

Hence, the radius of the new planet is found to be equal to the square root of 3 times the radius of the Earth (Square Root of 3 R).

Which are benefits of using nuclear power plants to generate electricity? Check all that apply.

lesya [120]

Below are the benefits of using nuclear power plants to generate electricity:

Nuclear power plants use simple power plant designs not vulnerable to human error or natural disasters.

Nuclear power plants use renewable fuel.

Nuclear power plants produce a large amount of energy for a small mass of fuel. Nuclear power plants produce no toxic waste products.

- The outflows of nursery gasses and in this manner the commitment of atomic power plants to an Earth-wide temperature boost is accordingly moderately little. The era of power through atomic vitality lessens the measure of vitality produced from non-renewable energy sources (coal and oil). Less utilization of petroleum products implies bringing down ozone-depleting substance outflows (CO2 and others).
