Question

If the acceleration due to gravity is
10m/s
and the units of

length and time are changed in kilometer and hour respectively, the
numerical value of the acceleration is​

Answer 1

Answer:

36 km/hr

Explanation:

10 m/s -------> km/h

1 m/s -------> 18/5 km/h

= 10 × 18/5

= 2 × 18

= 36 km/hr

Answer 2

$</p><p>\huge\underline\mathfrak\red{Explanation :}$

Acceleration due to gravity

$= 10 \: m{s}^{ - 2}$

→now , metre in kilometre

$= \frac{10}{1000} \: kms$

→'sec^2' in 'hr^2'

$= \frac{60 \times 60}{(60 \times 60) \times (60 \times 60)} \: ({hr})^{2} = \frac{1}{3600}$

→now , 'g' in kms/hr^2

$= </strong><strong>(</strong><strong>\frac{ \frac{10}{1000} }{ \frac{1}{3600} }</strong><strong>)</strong><strong> \: km \: {hr}^{ - 2}$

$= 36 \: km \: {hr}^{ - 2}$
