a 49N brick is placed in 1m^3 of oil. the volume of the oil raises to 1.025m^3. the weight of the brick in oil at the bottom of the pool weighs 26.51N
A. What are the forces acting on the brick when at rest on the scale at the bottom of the pool? Include their direction.
B. Which one of these forces is read by the scale?
C. From balancing the forces acting on the brick, calculate the buoyant force on the brick. Note: You cannot use the definition of the buoyant force since you do not know the density of oil.
D. Now calculate the density of the fluid (oil) from the definition of the buoyant force. Show your work for full credit.
