You're probably refering to a theory. A theory is a conceptual framework about a certain topic out of which we can infer many different hypothesis on the same topic that should prove to be correct. If they're not, then the theory is not a theory in reality, because the inferences made out of the theory are not correct.
The engine's efficiency is (35J)/125J) = 28% .
Do you have a different question to ask ?
Answer:
hi
Explanation:
i am giving you ans but this just my view
don't mind if it is wrong
ThIs is the same type of problem
find out the time value
3 = 1/2*a*T^2
6/10 = t^2
t = 0.77 seconds
and the distance is given 5 m
thus speed ,= distance/time
speed = 5/0.77
= 6.45 m/s
