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

Answer:

1.94 kg

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

$w_b=\frac{f}{g}$

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

so the mass of the block =$\frac{19}{9.8}=1.94\ kg$
