Which of the following are acceptable units for buoyant force? Choose all that apply.

psi
lb
tons
Pa
kg/L
kg
N
atm
N/m2

N, lb and tons.

N, lb, and tons is the correct answer!

Lb, N, Tons

I know that newtons are not sure about the others

I dont know what "acceptable" means. Lbs and tons can be force units.

To determine which units are acceptable for buoyant force, let's first understand what the buoyant force is. The buoyant force is the upward force exerted by a fluid (such as water or air) on an object submerged or floating in it.

From the given list, let's analyze each unit:

1. psi: Psi (pounds per square inch) is a unit of pressure and is not directly related to the buoyant force. It is not an acceptable unit for buoyant force.

2. lb: Pound (lb) is a unit of force commonly used to measure weight. It represents the gravitational force acting on an object. While lb is occasionally used in the context of buoyant force, it is not a standard unit for it. So, it is not an acceptable unit for buoyant force.

3. tons: Tons is a unit of weight, equivalent to 2,000 pounds. Like the pound, it is not a standard unit for buoyant force. Hence, it is not an acceptable unit for buoyant force.

4. Pa: Pascal (Pa) is the SI unit of pressure. The buoyant force can be expressed in terms of pressure, so Pa is an acceptable unit for buoyant force.

5. kg/L: Kilograms per liter (kg/L) is a unit used to measure density. While density is related to buoyancy (buoyant force is affected by the density of the fluid), kg/L is not a direct unit for buoyant force. Therefore, it is not an acceptable unit for buoyant force.

6. kg: Kilogram (kg) is the SI unit of mass and is not directly related to the buoyant force. It is not an acceptable unit for buoyant force.

7. N: Newton (N) is the SI unit of force, and it is an acceptable unit for buoyant force. The buoyant force can be expressed in terms of Newtons.

8. atm: Atmospheric pressure (atm) is a unit of pressure commonly used to measure the pressure exerted by the Earth's atmosphere. While it is related to pressure, it is not a standard unit for buoyant force. It is not an acceptable unit for buoyant force.

9. N/m2: Newton per square meter (N/m^2) is a unit of pressure and is an acceptable unit for buoyant force.

Therefore, the acceptable units for buoyant force are: Pa, N, and N/m^2.

Oh come on, which measure force?
