The centripetal force on the ball is 140.9 N; option A
<h3>What is the centripetal force on the ball?</h3>
The centripetal force on the ball is given by the formula below:
where;
- m is mass
- v is linear velocity
- r is radius
The linear velocity, v = wr
v = 5 * 2π/4.4 * 1.4 = 9.93 m/s
F = 10² * 2/1.4 = 140.9 N
In conclusion, the centripetal force is derived from the mass, velocity and radius of the path.

Earthquakes release energy in several forms: The energy in seismic waves that cause the ground to shake. Heat energy associated with friction on the fault slip surface. Gravitational potential energy (the energy stored when lifting something off the ground, for example) may change as a result of the earthquake.
Answer:
C
Explanation:
It says is it a good idea the person so 1 person can say no and the other one can say yes so it is asks for a opinion
A crazy sport thats kinda dangerous
Answer:
T = 0.003 s
(Period is written as T)
Explanation:
Period = time it takes for one wave to pass (measured in seconds)
frequency = number of cycles that occur in 1 second
(measured in Hz / hertz / 1 second)
Period : T
frequency : f
So, if we know that the frequency of a wave is 300 Hz, we can find the period of the wave from the relation between frequency and period
T = f =
to find the period (T) of this wave, we need to plug in the frequency (f) of 300
T =
T = 0.00333333333
So, the period of a wave that has a frequency of 300 Hz is 0.003 s
[the period/T of this wave is 0.003 s]
