solve this
means video i posted is correct!2nd Law of t.d
Kelvin Statement : we cannot get continuous work without expenditure of energy. Cold Body is necessary to transfer heat or to make a heat engine
Clausius statement : we can not transfer heat from cold body to hot body without expenditure of energy (as in Refrigerator)
i would suggest , just study every topic as briefly as possible ,dont get into unnecessary details
and there are people who call others kiddo..Come on , common sense is something, i m asking question from students of A2 , it would not be that simple...
Moreover , add the fact that its projectile motion or (the ball should cover some horizontal distance too
oh thanx alot really very nice... bro.if the total score of the 12 student class is x then x/12=70 and x=70×12=840
similarly if the total test score of the 18 student class is y then y18=80 so y=18×80=1440
the total combined is 1440+840=2280 so the average over the 30 students is 2280/30=76
76 degrees?Ok here is a question 4 u all, i know the ans but u all should try
I have to through the ball with a certain constant velocity so with what angle should i through it, so that i could cover same vertical and horizontal distance.....
57 yeah i think dhttp://www.pieas.edu.pk/admissions2012/Sample_Test_Paper_BS.pdf
physics 57 is D rite???
and how to deal with 58 ??? next one??
a prper working fr this one wil be awsome
thanx
and question 70) is again D rite???
and question 75 B is the ans????
76 degrees?
57 yeah i think d
58: i remember this formula {temp. in Celsius - 0}/100 = {temp. in Fahrenheit - 32}/180
In this 0 and 32 are the lower fixed points in both the scales respectively, 180 is the number of divisions on the Fahrenheit scale and 100 is the number of divisions o the Celsius scale.
You can take 100 and 212 instead of 0 and 32 as well
so you have: [450-0]/100 = 4.5 * 180 = 810 + 32 = 842
70 and 75 i think both are D
76 degrees?
