Questions
A steel ball of mass 0.1 kg falls freely from a height of 10 m and bounces to a height of 5.4 m from the ground. If the dissipated energy in this process is absorbed by the ball, the rise in its temperature is (specific heat of steel = 460 JKg-1K-1) (g = 10 ms-2).
detailed solution
Correct option is B
loss in Potential Energy = Heat Energy produced = Q and Q = ms∆t .Loss in Potential Energy =mg(H−h)=msΔt10(10−5.6)=460×Δt10×4.6=460×ΔtΔt=0.1∘CTalk to our academic expert!
