Answer:
V(peak voltage) is the highest voltage that the waveform will ever attain and the Vrms(root-mean-square) is the effective voltage of the total waveform representing the AC source.
Answer:
g = 12.22 m/s²
Explanation:
The time period of this pendulum is given as follows:

but the formula for the time period of a simple pendulum is as follows:

where,
L = length of pednulum = 48 cm = 0.48 m
g = magnitude of th gravitational acceleration on this planet = ?
Therefore,

<u>g = 12.22 m/s²</u>
The answer is a because it never needs to be insulated
Atoms from two different elements may have the same number of neutrons, but never the same number of protons
