Answer: The average speed over the entire trip is 3.94 m/s
Explanation:
As we know :
Let the distance of straight line from point to point be = d
Total distance covered = 2d
Time taken to cover the forward journey =
Time taken to cover the backward journey =
Total time for the journey = Time taken to cover the forward journey + Time taken to cover the backward journey =
Average speed =
Thus average speed over the entire trip is 3.94 m/s
The power dissipated by a resistor is equal to
where R is the value of the resistance and I is the current flowing through the resistor. From the formula, we can see that the larger R, the larger the dissipated power, so the greatest resistance dissipates more power.
