Answer: 1.59 sec
Explanation:
The kinetic energy contained in the rotation of the cylinder is 1/2 m v^2
The kinetic energy of translation is also 1/2 m v^2
so the total energy is m v^2
The force applied is mg sin (theta)
= m x 9.8 x 1/2
= 4.9 m
Now equate
F x d = m v^2
4.9 m x 3.1 = m v^2
v^2 = 4.9 x 3.1
v = sqrt(4.9 x 3.1) = 3.9 m/s
Acceleration.
V^2 = 2 a s
4.9 x 3.1 = 2 x a x 3.1
4.9 = 2 a
a = 2.45 m/s^2
Time
T = v/a
= 3.9/2.45
= 1.59 sec
Answer:
Electric field intensity is a Vector Field. Electric field intensity (E, N/C or V/m) is a vector field that quantifies the force experienced by a charged particle due to the influence of charge not associated with that particle
Explanation:
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
