Answer:
Charge
Explanation:
Unit of ampere is defined as the coulomb of charge per unit time which is in seconds.
Here, i is in ampere, qis the charge which is in coulomb, and the t is in sec which is time.
Therefore,
Charge=ampere-second.
Therefore, the unit ampere-second will represent the charge.
The apparent velocity is B) 48 m/s north
Explanation:
Here we have a problem of relativity of velocities.
In fact, the train is travelling north at a speed of
where this velocity is measured with respect to the ground.
At the same time, a passenger on the train is walking towards the rear (so, south) at a velocity of
where this velocity is measured with respect to the train, which is in motion in the opposite direction.
Therefore, the apparent velocity of the passenger with respect to an observer standing on the ground is:
And the direction is north, since this number is positive.
