How much time would it take to distribute one Avogadro number of wheat gains, if `10^10` grains each second?

A body at rest starts sliding from top of a smooth inclined plane and requires 4 second to reach bottom. How much time does it take, starting from rest at top, to cover one-fourth of a distance ?

Blood calcium level is a resultant of how much dietary calcium is absorbed, how much calcium is lost in the urine, how much bone dissolves releasing calcium into the blood and how much calcium from blood enters tissues. A number of factors play an important role in these processes. Mark the one which has no role

A certain amount is equally distributed among certain number of students. Each would get Rs. 2 less if 10 students were more and each would get Rs. 6 more if 15 students were less. Find the number of students and the amount distributed.

A particle performs S.H.M. of period 12 second and amplitude 8 cm. If initially the particle is at the position extremity , how much time will it take to cover a distance of 6 cm from the extreme position ?

A person trying to lose weight by burning fat lifts a mass of 10 kg upto a height of 1m is 1000 time . Assume that the potential energy lost each time be lower the mass is dissipated . How much far will be use up considering the work done only when the weight is lifted up ? Far supplies 3.8 xx 10^(7) J of energy per kg wich is canverted to mechanical energy with x 20 % efficiency rate Take = 9.8 ms^(-2)
