Answer:

At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels. ... Since most of the atmosphere's molecules are held close to the earth's surface by the force of gravity, air pressure decreases rapidly at first, then more slowly at higher levels.

What is the mass of an object that has a 250 N force moving at an acceleration of 10 m/s2 ?

zzz [600]

Answer: 25 kg

Identify the given information.
f = 250 N
a = 10 m/s^2

Choose which formula you should use. In this case, you are finding the mass.
The formula for force is f = ma, so, using this, it is easy to find the mass.

f = ma Divide by a for both sides
m = f/a Formula for mass!

The formula for mass is m = f/a, where f is force and a is acceleration.

Substitute.
m = (250 N)/(10 m/s^2)
m = 25 kg
