Calculating Upthrust and Fluid Forces

What happens to the pressure as you go deeper into a fluid?

• It remains constant.

• It increases.

• It fluctuates randomly.

• It decreases.

How is pressure calculated at a certain depth in a fluid?

• By subtracting depth from density and gravitational field strength.

• By adding density, depth, and gravitational field strength.

• By multiplying density, depth, and gravitational field strength.

• By dividing density by depth and gravitational field strength.

What is the relationship between pressure and depth for a submerged block?

• Pressure is only present on the sides.

• Pressure is greater at the top than at the bottom.

• Pressure is equal on all sides.

• Pressure is greater at the bottom than at the top.

What is the formula for calculating the upthrust on a submerged object?

• Density of fluid x Surface area of object x Gravitational field strength

• Density of object x Volume of fluid x Gravitational field strength

• Density of object x Surface area of fluid x Gravitational field strength

• Density of fluid x Volume of object x Gravitational field strength

What does the upthrust on a submerged object equal to?

• The density of the object.

• The weight of the fluid displaced.

• The volume of the object.

• The weight of the object.

In the example calculation, what is the upthrust acting on the concrete block submerged in water?

• 2000 Newtons

• 196 Newtons

• 980 Newtons

• 1020 Newtons

What determines whether an object sinks or floats in a fluid?

• The temperature of the fluid.

• The color of the object.

• The shape of the object.

• The comparison between the object's weight and the upthrust.

What happens when the density of the material is greater than the density of the fluid?

• The object dissolves.

• The object remains suspended.

• The object floats.

• The object sinks.

In mercury, why does the concrete block float?

• Because mercury is more dense than concrete.

• Because the block is heavier than in water.

• Because mercury is less dense than concrete.

• Because the block is lighter than in water.

What is the condition for an object to float when fully immersed?

• The upthrust is greater than the weight.

• The upthrust is equal to the weight.

• The upthrust is less than the weight.

• The upthrust is zero.
