The same net force is applied to object A and object B. The observed accelerations of the wo objects are not the same; object A has an acceleration three times that of object B.
Nhich of the following is correct?
A. Object A has one-third the mass of object B.
B. Object A has more friction than object B.
C. Object A has three times the mass of object B.
. Object A has a different, less streamlined shape than object B.

an obstruction

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

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
