Answer:
B. 14.4 N
Rotational speed (Angular Velocity) = 2
The Radius of the circle = 1.2 m
Velocity = Angular velocity × radius = 2×1.2 = 2.4 m/s
Centripetal force= mv²/r = 3 × 2.4×2.4/1.2 = 3 × 2.4 × 2
= 14.4 N
More efficient plumbing uses less water and creates smaller volume of waste is the answer why changing your toilet can reduce water pollution. If there is a problem in your toilet, you will use more water. The more water you pour, the more water pollution is added.
A conductor is important to science terms because conductors conduct heat which means they keep something hot. Insulators are the opposite.
Answer:
17.6kg.m/s in the opposite direction of the initial velocity.
Explanation:
In order to solve this we can use the Impulse-Momentum theorem:
We will assume the motion of the ball approaching the player as positive, so:
So the impulse is 17.6kg.m/s in the opposite direction of the initial velocity.
