Question

A block is suspended from a scale and then lowered into a bucket of water. The density of the water is 1 gm/cm3. The initial reading on the scale is 19N and one complete revolution of the scale is a change of 10N. 1) When the block is lowered into the water, the mass of the block:

Answer 1

1.94 kg

Step-by-step explanation:

we have given density of water = 1 gm/
`cm^3`

the initial reading of the scale = 19 N

change in reading of scale =10 N

we have to find the mass of the block when the block is lowered in water

mass of the block when it is lowered in the water is given by

`w_b=(f)/(g)`

here g is the gravity of acceleration which value is given by 9.8
`m/sec^2`

so the mass of the block =
`(19)/(9.8)=1.94\ kg`
