4 Suppose gas A is at temperature T and B is at temperature 2T, what is the relationship between the speed of sound in them? A A. Speed of sound in A is 2 times smaller than the speed of sound in B . Speed of sound in B is v2 times smaller than the speed of sound in A 2 T C. Speed of sounds in both the media are equal YRT D. None of the above m 5 Suppose one spring-mass system A has spring constant K and another spring-mass system B has spring constant 4K, and the mass attached to the springs is M, both the systems oscillate with the same amplitude A. What is the relationship between the maximum velocity during the oscillations? A. 1:2 B. 1:4 D B C. 1:8 K D. 1:16
