Water falls without splashing at a rate of `0.250 Ls^(-1)` from a height of 2.60 m into a 0.750kg bucket on a scale. If the bucket is originally empty, what does the scale read 3s after water starts to accumulate in it?

In a dam,water falls at a rate of 1000 kg s^(-1) from a height of 100 m . (b)Assuming that 60% of the energy of the falling water is converted to electrical energy,Calculate the power generated (Take g=9.8 m s^(-2) )

A 71 kg man stands on a bathroom scale in an elevator. What does the scale read if the elevator is ascending with an acceleration of 3.0" m"//"s"^(2) ?

Water is falling on the blades of turbine at a rate of 100 kg/s from a certain spring. IF the height of the spring be 100 m, the power transferred to the turbine will be

(Take C_(w)=4180 J kg^(-1) K^(-1)) A block of weight 5kg falls from a height of 5m into a bucket containing 10L of water. If all the mechanical energy of the block is used to heat water, find the rise in temperature of water. Take g= 10ms^(-2)

Water falls from a height of 60m at the rate of 15 kg/s to operate a turbine. The losses due to frictional force are 10% of the input energy. How much power is generated by the turbine?

A ball whose density is 0.4 xx 10^3 kg//m^3 falls into water from a height of 9 cm. To what depth does the ball sink ?
