Question

3.0 m s² = .......... km h⁻²

Answer 1

If you didn't get anything let us know.

Answer 2

Hii dear,
The question refers to 11th physics chapter Units and Measurements.

# Answer- 3.0 ms⁻² = 38880 kmh⁻²

# Explaination-
Suppose x be the value of blank here.
3.0 ms⁻² = x kmh⁻²

Here,
1 m = 10^-3 km
1 s = 1/3600 hr

Here,
x = 3×(10^-3)×(1/3600)^-2
x = 3×0.001×3600×3600
x = 38880

Hence, putting value x = 38880 in blank,
3.0 ms⁻² = 38880 kmh⁻²

Hope your doubt is cleared now.
