Answer:
The force exerted on a given area.
Option B is the right option.
Explanation:
<h2>
<u>About</u><u> </u><u>pressure</u></h2>
Pressure is defined as force acting per unit area. It's SI unit is Pascal or N/m^2.
Formula to find pressure is:
The force acting perpendicular on a surface is called the <u>thrust</u><u>.</u> It is a vector quantity.
<u>One </u><u>Pascal </u><u>pressure</u>
One Pascal pressure is defined as the pressure exerted in a surface of area m^2 by the thrust of 1 N
Hope this helps ..
Good luck on your assignment.....
Answer:
Clyde will provide greater impulse
Explanation:
We have given that Al exerts a force of 200 N for 5 sec
We know that impulse is given by, impulse = force ×time = 200×5 =1000 N-s
Bill exerts a force of 500 N for 2 sec
So impulse = 500×2 = 1000 N-s
Now the force exerted by Clyde 300 N for 4 sec
So impulse = 300×4 = 1200 N-s
From above calculation we can see that Clyde provide greater impulse than any other
Answer:
The correct answer for this Question is B
Explanation:
WIND AND WATER EROSION (B)
The radius of the curved road at the given condition is 54.1 m.
The given parameters:
- <em>mass of the car, m = 1000 kg</em>
- <em>speed of the car, v = 50 km/h = 13.89 m/s</em>
- <em>banking angle, θ = 20⁰</em>
The normal force on the car due to banking curve is calculated as follows;
The horizontal force on the car due to the banking curve is calculated as follows;
<em>Divide </em><em>the second equation by the first;</em>
Thus, the radius of the curved road at the given condition is 54.1 m.
