a stone is thrown vertically upwards with an initial velocity of 40ms . find the maximum height reached by the stone. what is the net displaysment and the total distance covered by the stone?

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
