ques:the speed of sound in oxygen at a certain temp is 460 ms-1 .the speed of sound in he at same temp will be (assume both gases to be ideal)
a)460 ms -1 c)650 ms-1
b)500 ms -1 d)330 ms-1
ques:an athele in the olympics games covers a distance of 100 m in 10 s.his kinetic energy can be estimated to be in the range
a)200j-500j c)2x105j-3x105j
b)20,000j-50,000j d)2,000j-5,000j
thanks
