What is the gravitational force on a 70kg that is 6.38x10^6m above the earths surface

171.5 N

Explanation:

The gravitational force on an object due to the Earth is given by

where

m is the mass of the object

g is the acceleration due to gravity

The acceleration due to gravity at a certain height h above the Earth is given by

where:

G is the gravitational constant

is the Earth's mass

is the Earth's radius

Here,

So the acceleration due to gravity is

We know that the mass of the object is

m = 70 kg

So, the gravitational force on it is

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas
