Question

Sally places a jar with some pennies into a pool of water and exactly half of the jar is submerged. The volume of the jar is 200 cm3 and the density of the water is 1 g/cm3.

a. What is the buoyant force acting on the jar?
b. What is the weight of the jar and pennies?
c. What is the density of the combined jar and pennies?

Answer 1

Bouyant Force = 0.9N

The density of the jar and Penny was not given so we can't determine it's weigh and combined density

Step-by-step explanation:

Bouyant force Fb = Volume of solid*density of liquid*acceleration

Fb= (200/2)*1*980.665

Fb= 98066.5/100000

Fb= 0.9N
