Answer:
Energy= 46.08KJ
Explanation:
Given that the power needed to light each bulb is 32W
We know that Power =
The energy needed to light one bulb=
Given time = 1minute = 60 seconds
Energy = =1920J
Therefore energy needed to light one bulb is 1920J
The energy needed to light 24 bulbs = =46080J=46.08KJ
Answer:
The potential difference between the places is 0.3 V.
∴ 1st option i.e. 0.3V is the correct option.
Explanation:
Given
Work done W = 3J
Amount of Charge q = 10C
To determine
We need to determine the potential difference V between the places.
The potential difference between the two points can be determined using the formula
Potential Difference (V) = Work Done (W) / Amount of Charge (q)
or
substituting W = 3 and q = 10 in the formula
V
Therefore, the potential difference between the places is 0.3 V.
∴ 1st option i.e. 0.3V is the correct option.
