Жердің радиусы 6400км еркін түсу үдеуі9,8м/с2 ал оның массасы қанша

Answer 1

Earth's Radius and Surface Gravity

The radius of the Earth is approximately 6400 kilometers and its surface gravity is 9.8 m/s^2.

The mass of the Earth can be calculated using the formula for surface gravity:

g = G * (M / r^2)

Where: - g = surface gravity (9.8 m/s^2) - G = gravitational constant (approximately 6.674 × 10^-11 N m^2/kg^2) - M = mass of the Earth - r = radius of the Earth (6400 km)

By rearranging the formula, we can solve for the mass of the Earth:

M = g * r^2 / G

Substituting the given values: - g = 9.8 m/s^2 - r = 6400 km (converted to meters: 6400 * 1000 = 6,400,000 m) - G = 6.674 × 10^-11 N m^2/kg^2

We can calculate the mass of the Earth using these values.
