Question

if the unit of power is million erg/minute ,the unit of force is 1000 dyne and the unit of length is 5/3cm then yhe unit of time is

Answer 1

Expression for the power,$P=\frac{Fl}{t}$

We can also write, $t=\frac{Fl}{P}$  

Here, F is the force, l is length and t is the time.

Given, $P= million erg/minute= 10^{6} erg/minute$,$F=1000 dyne$ and $l =\frac{5}{3} cm$.

Therefore, after substituting these values in above relation we get

$t=\frac{1000}{10^{6} } \times\frac{5}{3} \times60$

$t= \frac{30}{300} =\frac{1}{10} s$

Thus, the unit of times is $\frac{1}{10} s$

Answer 2

Answer:

If the unit of power is 10erg/sec ,the unit of force is 1000 dyne andunit of time is 1 minute calculate the unit of mass and length
