Assuming that the pressure inside the house is at atmospheric pressure, the force on the window is approximately 1378 Newtons.
Given the data in the question;
- Area of the window;
- Velocity of wind;
Force on the window;
<h3>Force</h3>
Force is an influence that can cause the change of motion of a particle or object. Also, force normal to the area of a surface is equal to pressure multiply by the area of that surface.
Where P is pressure and A is area of the surface.
Also, we know that;
Where is density of air, approximately( ) and V is velocity.
Hence
We substitute our values into the equation above
Therefore, Assuming that the pressure inside the house is at atmospheric pressure, the force on the window is approximately 1378 Newtons.

Answer:
It takes you 32.27 seconds to travel 121 m using the speed ramp
Explanation:
<em>Lets explain how to solve the problem</em>
- The speed ramp has a length of 121 m and is moving at a speed of
2.2 m/s relative to the ground
- That means the speed of the ramp is 2.2 m/s
- You can cover the same distance in 78 seconds when walking on
the ground
<em>Lets find your speed on the ground</em>
Speed = Distance ÷ Time
The distance is 121 meters
The time is 78 seconds
Your speed on the ground = 121 ÷ 78 = 1.55 m/s
If you walk at the same rate with respect to the speed ramp that
you walk on the ground
That means you walk with speed 1.55 m/s and the ramp moves by
speed 2.2 m/s
So your speed using the ramp = 2.2 + 1.55 = 3.75 m/s
Now we want to find the time you will take to travel 121 meters using
the speed ramp
Time = Distance ÷ speed
Distance = 121 meters
Speed 3.75 m/s
Time = 121 ÷ 3.75 = 32.27 seconds
It takes you 32.27 seconds to travel 121 m using the speed ramp

The nuclear force does not work
under long distances
is greater in strength the the electomagnetic force when the distances are small.
I'm not sure what D means.
I think it does depend on charge.
You have to choose D but this is a notes question and I'm not at all certain of the answer.
