Question

On a given planet, the weight of an object varies directly with the mass of the object. suppose that an object whose mass is 10 kg weighs 90 n. Calculate the mass of another object that weighs 36 n.

Answer 1

`(10)/(x)=(90)/(36)`
`10\cdot36=90x`
`(360)/(90)=x`
`x=4`

the mass of the object that weighs 36 n is 4 kg
