-6.98 × 10-^7 is the answer <3
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:
Explanation:
d = 42 meters
v = 12 m/s
t = ?
t = d/v
t = 42 / 12
t = 3.5 seconds. That's awfully fast.

If we put a resistor in circuit it will slow the speed of current
Let's check ohms law
- So if resistance is more current is less
#17
Again use ohms law
- Voltage must be increased
