Using F = Ke
F = 39200×(25÷100) = 39200×0.25
F= 9800N
Answer:
B - Earth's path around the Sun
Explanation:
Volocity can be the wave length of the speed like the volume.
Answer:
ω = 0.05 rad/s
Explanation:
We consider the centripetal force acting as the weight force on the surface of the cylinder. Therefore,

where,
ω = angular velocity of cylinder = ?
g = required acceleration = 9.8 m/s²
r = radius of cylinder = diameter/2 = 5.9 mi/2 = 2.95 mi = 4023.36 m
Therefore,

<u>ω = 0.05 rad/s</u>
The answer is A. Friction
hope this helps :)
