  4. DA body is dropped on ground from a height h _ 1 and after hitting the ground, it rebounds to a height h _ 2 . If the

Correct answer

B. A body is dropped on ground from a height h _ 1 and after hitting the ground, it rebounds to a height h _ 2 . If the

Step-by-step solution

Vms=3RTM Vrms2=3RT/M\begin{aligned} & \mathrm{V}_{\mathrm{ms}}=\sqrt{\frac{3 \mathrm{RT}}{\mathrm{M}}} \\ & \mathrm{~V}_{\mathrm{rms}}^2=3 \mathrm{RT} / \mathrm{M} \end{aligned} Hence we can conclude that Vrms2\mathrm{V}_{\mathrm{rms}}^2 is directly proportional to temperature y=mx⇒\mathrm{y}=\mathrm{mx} \Rightarrow Graph will be straight line
