Asked by Melaku

Arock weighs 1000N in air and 609N in water.Find its volume.
Answered by lil help
1. Apply equilibrium to the rock when it is submerged in water.
2. Solve the equation from step 1 for volume

1. Equilibrium:
{Force to hold rock stationary in water (apparent weight)}+ {Buoyant Force on rock} = {Weight of rock in air ¾}

V=1000N-609N/9810N/m^3=0.0399 m^3
V=39.9L
