An office window has dimensions 3.1 m by 2.1 m. As a result of the passage of a storm, the outside air pressure drops to 0.954 atm, but inside the pressure is held at 1.0 atm. What net force pushes out on the window

Net forces which pushes the window is 30342.78 N.

Explanation:

Given:

Dimension of the office window.

Length of the window = m

Width of the window = m

Area of the window =

Difference in air pressure = Inside pressure - Outside pressure

                                           = atm = atm

Conversion of the pressure in its SI unit.

⇒   atm = Pa

⇒ atm = Pa

We have to find the net force.

We know,

⇒ Pressure = Force/Area

⇒

⇒

⇒ Plugging the values.

⇒

⇒ Newton (N)

So,

The net forces which pushes the window is 30342.78 N.

whichever one it is, it's definitely not one that you included on the list you provided.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
