A copper wire of 3m length and 1mm diameter is subjected to a tension of 5kg weight. Calculate the elongation produced in the wire, if Young's modulus of elasticity of copper is 120G Pa

waste

explanation:

the answer is 46 mls because when you add the speed per second it increses the speed

c) up

hope this

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
