Calculating Force from Pressure and Area

In summary, the question is asking for the force on a south-facing side of a cube container filled with gas at a pressure of 3.7 x 10^5 Pa. The container is 0.10 m on each side and the answer should be in kN. To find the force, we need to convert Pa to N/m^2 and calculate the force on the face using the surface area and pressure.

I've been having trouble figuring out this question:

A container is filled with gas at a pressure of 3.7 times 10^5 Pa. The container is a cube, 0.10 m on a side, with one side facing south. What is the magnitude of the force on the south side of the container due to the gas inside? Answer must be in kN.

Thanks to those that help :)

Welcome to the PF.

What are the sub-units of Pascals? If a Pa is a unit of pressure, it will be made up of units of Force and Area, correct? What are Pa in terms of Newtons and square meters? What is the surface area of that face they are asking about? So then, what would be the total force on that face from the pressure?
 

1. What is magnitude of force?

The magnitude of force is a measure of the strength or intensity of a force. It is represented by a numerical value and a unit of measurement, such as Newtons (N) or pounds (lbs).

2. How is magnitude of force calculated?

The magnitude of force is calculated by multiplying the mass of an object by its acceleration. This is described by the formula F=ma, where F represents force, m represents mass, and a represents acceleration.

3. How is magnitude of force different from direction of force?

The magnitude of force refers to the strength of a force, while the direction of force refers to the path or angle that the force is applied in. Both magnitude and direction are necessary to fully describe a force.

4. Can magnitude of force be negative?

Yes, the magnitude of force can be negative. This indicates that the force is acting in the opposite direction of the positive direction. For example, a force of -10N would indicate that the force is acting in the negative direction with a strength of 10N.

5. How does magnitude of force affect an object's motion?

The magnitude of force can determine the acceleration of an object. The greater the magnitude of force, the greater the acceleration will be. This can change an object's speed, direction, or both, depending on the direction of the force and the object's initial motion.
