For an object in circular motion, the centripetal force is given by:
where
m is the mass of the object
v is the tangential speed of the object
r is the radius of the circular path
Therefore, we see from the formula that there are three physical quantities that affect the value of the centripetal force: the mass of the object, its speed and the radius of its orbit.
The question is defective. If her acceleration is 2.5 m/s/s, then her speed is 2.5 m FASTER each second, and she will never stop.
To find the net charge you take the number of protons and subtract the number of electrons, and the answer will be your charge.
This atom has 11 electrons AND 11 protons
11 - 11 = 0 net charge
It appears to be a <span>spiral shape. </span>
First we need to convert the frequency to the correct SI units (seconds)
Frequency of bell = 1440/60 = 24 Hertz (Strikes per second)
Power is the rate of work being done or the work done per second.
P = E/t = (24 * 0.2)/1 = 4.8 Watt
