The frequency of the pendulum is independent of the mass on the end. (c)
This means that it doesn't matter if you hang a piece of spaghetti or a school bus from the bottom end. If there is no air resistance, and no friction at the top end, and the string has no mass, then the time it takes the pendulum to swing from one side to the other <u><em>only</em></u> depends on the <u><em>length</em></u> of the string.

The gravitational force exerted by the earth on a person standing on the earth's surface is 602.74 N.
<h3>What is the gravitational force of the earth on the person?</h3>
The gravitational force exerted by the earth on a person standing on the earth's surface is given below as follows:
where
G = 6.67 * 10⁻¹¹
m¹ = 62 kg
m² = 5.97 * 10²⁷ kg
r = 6.4 * 10⁶ m

Therefore, the gravitational force exerted by the earth on a person standing on the earth's surface is 602.74 N.

Answer:
2000 V/m
1778021.69323 m/s
Explanation:
V = Voltage = 9 V = 
q = Charge of proton = 
m = Mass of electron = 
v = Velocity of electron
Electric field is given by

The electric field is 2000 V/m
Here, the energy of the system is conserved

The velocity of the electron is 1778021.69323 m/s
