Question

Given the value for the universal gravitational constant, the average value for the acceleration due to gravity at the surface of Earth, and the radius of Earth, Earth’s mass is ____ x 10^24 kg.

A. Calculated

B. Estimated

C. Measured

D. Determined

Answer 1

The mass of Earth can be determined using the values for the universal gravitational constant, the average value for the acceleration due to gravity at the surface of Earth, and the radius of Earth.

The correct answer is D. Determined.

Step-by-step explanation:

The correct answer is D. Determined.

Earth's mass can be determined by using the values for the universal gravitational constant (G), the average value for the acceleration due to gravity at the surface of Earth (g), and the radius of Earth (R).

The formula to calculate Earth's mass (M) is: M = (g * R^2) / G.

By plugging in the given values, the mass of Earth can be determined.

The mass of Earth can be determined using the values for the universal gravitational constant, the average value for the acceleration due to gravity at the surface of Earth, and the radius of Earth.
