Answer:
63 m
Explanation:
The initial velocity of the motorcycle is
The final velocity is
And the time taken is
Since the acceleration of the motorcycle is uniform, we can find the distance traveled by the motorcycle during this time by using the following SUVAT equation:
Substituting numbers into the equation, we find
Answer: When
Explanation:
According to first law of thermodynamics, energy can neither be created nor be destroyed. It can only be transformed from one form to another.
= change in enthalpy
P = pressure
= change in volume
=Change in internal energy
q = heat absorbed or released
w = work done on or by the system
Thus for ,
The heat evolved or absorbed by the system in a physical or chemical process, equal the change in enthalpy of the system when
