Explanation

 7t

First person distance traveled in time t = 28

 laps = 1

4 laps 

 Distance covered by the second person at time t = 38

 laps 

 First-person speed = 14t

 Second-person speed = 38t

 The two  start from A and B respectively, so they  meet  when there is a difference of 78

 laps. 

 Relative velocity of A and B: 

 = (38t-14t) = 18t

 Time  to complete 78

 laps at this speed: 

 = (78 × 8t) = 7t

Explanation

• Photovoltaic (PV) cells convert solar energy into electricity through a physical and chemical phenomenon known as the photovoltaic effect.
• Photovoltaic cells are also called solar cells.
• They convert light energy from the Sun directly into electrical energy.
