Question
Your locker gets messier each week. In this case, the entropy of your locker is ___________ decreasing increasing staying constant none of these You apply torque when you __________ open a door use a wrench turn a steering wheel all of them A wave in which the particles of the medium move perpendicular to the direction of the wave motion is called _________ wave longitudinal transverse both A and B neither A nor B A heat engine operates between a hot temperature T_hot = 2500 K and a cold temperature T_cold = 500 K. What is the maximum efficiency of the engine? 5 % 20 % 50 % 80 %Explanation / Answer
22. As the randomness increases, entropy increases.
23. All of them. As torque is the product of force and the perpendicular distance of application from the axis to the point of application of force. It is true in all the above cases.
24. Transverse wave.
25. Efficiency= 1-( Tc/Th)
= 0.8
= 80%
