Question

complete the following table​

Answer 1

Answer:

• W = 800, P = 3

Explanation:

As we know, the formula to find pressure is

= Pressure = Force/Weight

In the 1st column,

Given -

• Pressure (Nm^-2) - 20,000
• Area (m²) - 0.04
• Weight (N) - ?

To find -

• What is the weight?

Solution -

Pressure = Area/Weight

20,000 = 0.04/W

W = 20,000 × 0.04

W = 800

In the 2nd column,

Given -

• Pressure (Nm^-2) - ?
• Area (m²) - 500
• Weight (N) - 1500

To find -

• What is the pressure?

Solution -

Pressure = Area/Weight

P = 500/1500

P = 3
