<span>Radius = 4.6 m
Time for one complete rotation t = 5.5 s.
Distance = 2 x 3.14 x R = 2 x 3.14 x 4.6 m = 28.888.
Velocity V = distance / time = 28.888 / 5.5 s = 5.25 m/s
Force exerted by cat Fc = mV^2 / R = (mx 5.25^2) / 4.6 m
Force of the cat Fc = 6m, m being the mass.
Normal force = Us x m x g = Us x m x 9.81 = Us9.81m
equating the both forces => Us9.81m = 6m => Us = 6 / 9.81 => Us = 0.6116
So coefficient of static friction = 0.6116</span>
Answer:
Loss of momentum
Explanation:
Centripetal force is the name given to any force which causes a change in direction of velocity toward the center of the circular motion. The component of the force which is perpendicular to the velocity is the part resulting in the centripetal force

The currency for performing work is called : Energy
And Energy's unit of measurement is : Joule
The amount of energy you've inputed will always equal the output.
For example, in order to do a 500 joules of work, you need 500 joules of energy
The sound wave travels faster at higher temperatures and slower at lower temperatures.
<h3>What will happen to the velocity of the wave if the temperature decreases?</h3>
At a lower temperature, particles of the medium are moving more slowly as compared to higher temperature. Due to lower temperature, longer time is required to transfer the energy of the sound waves.
So we can conclude that sound travels faster at higher temperatures and slower at lower temperatures.
