Answer:
36 N
Explanation:
The tension on the string :
T =mv²/r ------where
m= mass of object = 8 kg
v= tangential velocity = 3 m/s
r= length of the string = 2m
T= [ 8 * 3² ] / 2
T= 36 N
Setting fishing limits on certain fish species is essential because if overfishing is allowed, the fish won't be able to reproduce fast enough to outpace their removal. Fishing limits also put more emphases on catching other species, which protects the original species from predators.
Answer:
Air slows down The fall of any object including a ball.
The centripetal force : F = 293.3125 N
<h3>
Further explanation
</h3>
Given
mass = 65 kg
v = 9.5 m/s
r = 20 m
Required
the centripetal force
Solution
Centripetal force is a force acting on objects that move in a circle in the direction toward the center of the circle
F = centripetal force, N
m = mass, Kg
v = linear velocity, m / s
r = radius, m
Input the value :
F = 65 x 9.5² / 20
F = 293.3125 N
