Answer:
we must multiply the speed value by 3.6
Explanation:
To reduce a magnitude from one unit to another, it must be multiplied by the equivalence in the order necessary so that the units do not change.
To reduce speed from m / s to km / h
we write the speed and the two conversion factors
v [m / s] [1 km / 1000m] [3600 s / 1h
v 3600/1000
v 3.6
therefore we must multiply the speed value by 3.6
Answer:
Rusting of iron is slow in desert area because rusting happens when iron articles react with atmospheric oxygen and moisture and produced a substance called rust. in desert areas there is less moisture in air as compared to coastal area therefore rusting is slow.
