Answer: 1350J
Explanation:
To solve this, we are going to use the formula for calculating potential difference which is:
Potential difference (V) = Work done (W) / Total charge (C)
Therefore,
9 volts = Work done / 150
Work done = 150 × 9 = 1350J
Velocity is speed plus direction, so an example of velocity would be a vehicle traveling at 75mph north. Velocity is a vector quantity because it describes both magnitude and direction.
A lot of windows, skylights, and open floor areas.
