What is buoyancy?
The force exerted by gravity on a submerged object
The force exerted by an object on a fluid
Upward force exerted by a fluid on a submerged object
The force exerted by a fluid on a floating object
What is the formula to calculate buoyant force?
Buoyant force = Weight of the fluid displaced
Buoyant force = Mass of the object
Buoyant force = Volume of the object
Buoyant force = Density of the fluid
How does a hydraulic lift work based on Pascal's principle?
The pressure applied to the fluid is only transmitted vertically
The pressure applied to the fluid is transmitted faster than the speed of light
The pressure applied to the fluid is transmitted in a random direction
The pressure applied to the fluid is transmitted equally in all directions

Magic
Why does ice float?
water expands when it freezes, making ice less dense than water
water compacts when it freezes, making ice more dense than water
hydrogen bonds in water push the ice to the surface
ice is afraid of water, and avoids it
