The bicycle is 92% efficient, meaning 92% of energy input is converted to useful (in this case kinetic) energy. Just find 92% (=0.92) of the given input. So:
100*0.92 = 92J
acceleration = change in velocity /change in time
convert 40km to meter then divide it with 5
I am pretty sure that electromagnetic Induction states that moving a magnet through a loop of wire creates B. magnetic field. I consider this option to be correct because according to lenz's law <span>conductor moves through loop and to be more exact in this case through a magnetic field. I hope it help!</span>
Answer:
8N
Explanation:
the body is subjected to pressure equals to force force inverse to the area of that body given that it is in motion
Answer:
Explanation:
Given
mass of bus along with travelers travelling in North direction is 
speed of bus towards North 
mass of bus travelling in South direction is 
speed of bus 
mass of each Passenger in south moving bus 
Momentum of North moving bus
Momentum with south moving bus
For total momentum to be towards south
should be greater than 0
thus for least value of n
