  20. As Vs is very small than c we can neglect it in addition or subtraction so finally we can get the expression in the form of c/c which is 1 . but I dont see any of that here??

  24. in a water fall water is falling from a height of 100metre so what is temp difference between top of the water fall to bottom of the water fall.
    9 years ago by Tusharkanta mahapatra
    Ans 1 ->
    Due to air friction only the temperature of water fall increases not due to work done by gravity during its fall... When water strikes the bottom of fall and comes to rest then work done by gravity will increase its temp... which can be easily obtained by using the relation mgh = ms delta(t)
