IUPAC KE KUCH AUR HURDLES

An electron accelerated through a potential difference of 0.1V from rest attains a KE (KE_e) also there is a molecule of nitrogen gas having temperature 300K and KE (KE_(N_2)) . Find (KE_(e))/(KE_(N_2))

Ratio of rotational K.E. to rolling KE. of a solid sphere is

In an elastic collision (A) Both momentum and KE are conserved (B) only momentum is conserved (C) only KE is conserved (D) Neither KE nor momentum is conserved

A body is rolling down an inclined plane. If K.E. of rotation is 40% of K.E. in translatory state, then the body is a

Assertion : The graph of PE and KE of a particle is SHM with respect to position is a parabola Reason : This because PE and KE not vary linear will position

The average K.E. of hydrogen molecules at 27 °C is E. The average K.E. at 327 °C is

A body is rolling down an inclined plane. If K.E. of rotation is 40% of K.E. of translation, then body is
