Physics And Measurement Question 226

Question: In a certain system of units, 1 unit of time is 5 sec, 1 unit of mass is 20 kg and 1 unit of length is 10m. In this system, one unit of power will correspond to-

Options:

A) 16 watts

B) $\frac{1}{16}$ watts

C) 25 watts

D) $\frac{1}{25}$ watts

Show Answer

Answer:

Correct Answer: B

Solution:

[b] $1 s e c * = 5 s e c, 1 k g * = 20 k g, 1 m * = 10 m$

$1 w a t t = 1 k g m^{2} \sec^{- 3}$

$= \frac{1}{20} k g * {(\frac{1}{10} m *)}^{2} {(\frac{1}{5} \sec *)}^{- 3}$

$= \frac{1}{20} \times \frac{1}{100} \times 125 k g * m *^{2} \sec *^{- 3}$ =

$\frac{1}{16} w a t t *$
