im having a really hard time trying to figure this out.
An ore sample weighs 19.8 N in air. When the sample is suspended by a light cord and totally immersed in water, the tension in the cord is 11.5 N.
Find the total volume of the sample.
Take the density of water to be rho_water = 1000 kg/m^3 and the free fall acceleration to be g = 9.80 m/s^2.
heres the equation i figured out for this type of problem.
force of buoyancy=density*volume* gravity.
alright is the force of buoyancy for air and water 19.8 and 11.5 respectively?
if so won't i just have to multiply grvity times thhier densities divided by the force to find the volumes then add them up?
