A raindrop of mass 1.00 g falling from a height of 1 km hits the ground with a speed of 50 m s–1. Calculate (a) the loss of P.E. of the drop. (b) the gain in K.E. of the drop. (c) Is the gain in K.E. equal to loss of P.E.? If not why. Take g = 10 m s-2 |
|
Answer» (a) Loss of PE = mgh = 1 x 10-3 x 10 x 10-3 = 10J (b) Gain in KE = (1/2)mv2 = (1/2) x 10-3 x 2500 = 1.25J (c) No, because a part of PE is used up in doing work against the viscous drag of air. |

Roma enjoys to ride fastly on a swing. So Rano stands behind the swing every time Roma rides it and pushes her. However, Rano also gets scared of Roma riding too fast and keeps yelling out to her to be careful. However, Roma refrains from being slow.(a) What energy conversion takes place on a swing? (b) Muscular energy of Rano converts to which energy on pushing the swing? (c) Compare the qualities of Roma and Rano. |
|
Answer» a) The energy conversion which takes place is the change of the potential energy of the Rano while standing on the swing into the kinetic energy of the swing due to which the speed of the swing increases. (b) The muscular energy of Rano is not converted into the specific form of the energy but it is imparted as the additional kinetic energy to the swing which makes the swing fast. (c) Roma is adventurous and courageous while Rano is timid and fearful. Also, Roma is risk-taking and Rano is very careful. |
