Answer: The current must be equal to
amps, or ~0.9574 amps.
Explanation:
You can find the current in amperes using ohms and watts from this formula:

Where P represents power in watts, R represents resistance in ohms, and I represents current in amperes.
You can then substitute 60 and 55 into the equation to find I:

Then, simplify the denominator:

Rationalize the denominator:

Simplify the numerator by finding its factors:

The current must be equal to
amps, or ~0.9574 amps.

Below is an attachment containing the solution.
The correct answer is
<span> (3) 3.2 × 10^−19 C
In fact, electric charge is quantized: the elementary charge is the charge of the electron, </span>

, and every particle can only have an electric charge which is an integer multiple of this value. Of the options listed above, only option (3) is an integer multiple of the elementary charge: in fact, it corresponds to 2 times the electron charge:
Longitudinal wave is a wave in which the motion of the medium's particles is parallel to the direction of the energy transport.
