Question

write the dimensional formulae of following with proper calculation. (1) work (2) Resistance (3) Impluse
​

Answer 1

Answer:

The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work. A newton-meter is the same thing as a joule, so the units for work are the same as those for energy – joules.

Explanation:

Terminal voltage is the voltage output of a device is measured across its terminals. Terminal voltage is calculated by V = emf – Ir.An impulse is equal to the net force on the object times the time period over which this force is applied. Below, we derive impulse from the equation F = ma, which comes from Newton's second law of motion.
