DC -- buoyancy and Young's modulus

What is the equation to calculate Young's Modulus?

• Young Modulus = E = ^Stress/_Strain

• Young's Modulus = E = mc²

• Youngs modulus = E =^Strain/_Stress

• Young's Modulus = E = ¹/₂Fx

• 3, 4, 2, 1, 
• 4, 3, 1, 2

What direction is the buoyant force in?

• Downward
• Left
• Right
• Upward

• True
• False

Which of the following statements is true about the buoyant force on an object that is floating on the surface of a lake?

• The buoyant force is greater than the weight of the object.

• The buoyant force is equal to the weight of the fluid displaced.

• The buoyant force is the same as when the object is completely submerged.

• The buoyant force is less than the density of the water.
