How the answer of second MCQs comes
@@MuzammilHussain-t4x I have mistakenly interchange 4 and 6 Thank you for pointing out that, Temperature will be the same according to environment. and Body will become equilibrium with surrounding
10th is impulse not forces????
have you read Newton's second law?? The rate of change of momentum is called force, which can be expressed as F = ∆p/∆t And the other hand impulse is express as F∆t=∆P
@@sahaqhashum347 l know later sorry l forgot to delete comment

@@sahaqhashum347 ok
I don't think 16 one is correct...can you explain please
Thank you for pointing it out Your Right option D is also correct, because turbines also convert mechanical energy into heat energy . However option A is not wrong either, Options D is best

Oh bhie fill bhi karo
What??
Key?@@sahaqhashum347

Sir! your second answer is 86.4F and in the book it is 84.6F your one is wrong.
Yeah your right, I have mistakenly interchange 4 and 6 Thank you for pointing out that, I will correct it from my Solution manual
