Answer:
0.11 m/s and 0.28 m/s
Explanation:
Average velocity is defined as the ratio of total displacement covered to the total time taken.
For first 0.25 m
Total displacement = 0.25 m
Total time taken = 2.23 second
Average velocity = 0.11 m/s
For second 0.25 m
Total displacement = 0.50 - 0.25 = 0.25 m
Total time = 3.13 - 2.23 = 0.9 second
Average velocity = 0.28 m/s

Answer : Total energy dissipated is 10 J
Explanation :
It is given that,
Time. t = 10 s
Resistance of the resistors, R = 4-ohm
Current, I = 0.5 A
Power used is given by :
Where
E is the energy dissipated.
So, E = P t.............(1)
Since,
So equation (1) becomes :
So, the correct option is (3)
Hence, this is the required solution.
