Height (h) = 1.5 m
Gravity (g) = 9.81 m/s²
Work done = ?
Work done
= mgh
= 5 kg × 9.81 m/s² × 1.5 m
= 73.575 joule (J)

The answer is 30 because you put 21/x= 70/100
you cross multiply 100 and 21 you get 2100 and you divide it by 70 you should get 30 cause you take out one 0 from both numbers and end up with 210 divided by 7 then you get 30
to make the proportion we make the ratio of the similar sides
For example
4/8 = 12/x
or we can write it as 4/12 = 8/x
or 12/x = 4/8
So last option is correct
