Question

Inside a pressurized tube there is air with a pressure of 750,000Pa. If the top face of the tube has area 15cm², how much force is pushing on the top face of the tube?

Answer 1

The force pushing on the top face of the tube is 1,125 Newtons

Step-by-step explanation:

To calculate the force pushing on the top face of the tube, we can use the formula:

Force = Pressure x Area

In this case, the pressure is given as 750,000 Pa and the area of the top face of the tube is 15 cm². However, we need to convert the area to square meters before we can use the formula:

15 cm² = 0.0015 m²

Now we can substitute the values into the formula:

Force = 750,000 Pa x 0.0015 m²

Force = 1,125 N

Therefore, the force pushing on the top face of the tube is 1,125 Newtons
