Answer:
Meter
Explanation:
I'd say meters, cause it's the SI unit of length,
which is a Derived Quantity.
A scalar quantity is a measurement of a quantity, like temperature, or mass.
<u>Answer:</u> The voltage needed is 35.7 V
<u>Explanation:</u>
Assuming that the resistors are arranged in parallel combination.
For the resistors arranged in parallel combination:
We are given:
Using above equation, we get:
Calculating the voltage by using Ohm's law:
.....(1)
where,
V = voltage applied
I = Current = 3.75 A
R = Resistance =
Putting values in equation 1, we get:
Hence, the voltage needed is 35.7 V
if one of the charge is doubled, the electric potential energy would be doubled too
