An engine manufacturer makes the claim that the engine they have developed will, on each cycle take 100 J of heat out of boiling

water at 100 deg C, do mechanical work of 80J, and exhaust 20 J of heat at 10 deg C. What, if anything, is wrong with this claim? A) An engine would operate by taking in heat at the lower temperature and exhausting heat at the higher temperature, B) There is nothing wrong with this claim because 100J= 20j + 80J, C) The heat exhausted must always be greater than the work done according to the second law of thermodynamics, D) The efficiency of this engine is greater than the ideal Carnot cycle efficiency.

A light wave traveling through medium 1 strikes a boundary with medium 2 at at a 45 degree angle. the light then enters the seco
Alona [7]

Here light ray strikes to interface at an angle of 45 degree and then refracts into other medium such that it will bend towards boundary.

So here the angle of incidence will be less than the angle of refraction as light moves towards the boundary after refraction which mean it will bend away from the normal

here it can be said that medium 2 will be rarer then medium 1

So here the possible options are

1. Water  

Air

2. Diamond  

Air

So in above two options medium 1 is denser and medium 2 is rarer
