Answer : The correct options are, (B) a newton-meter and a joule and (C) a newton and a joule/sec
Explanation :
As we know that,
or we can say that,
From the given options, the option B and C are the equivalent units.
Hence, the correct options are, (B) and (C)
Kinetic energy since if its rolling is already using the stored potential energy that it had before it was given an amount of energy to release it for a given time
The outside temperature is one of them, its material another, and the last one is its mass.
if the velocity of the car reduces from 70km/h to 50km/h then the speed of the car will be equal to the speed of the lorry...
thus the relative velocity will be 0
We know that impulse is simply the product of Force and time:
Impulse = Force * time
Since Force has a unit of Newton or kg m/s^2 and time is in
seconds, therefore impulse can have units as:
N s
or
