Answer 2

Calculating Air Pressure on the Desk

To calculate the force exerted by the air on the desk, we can use the formula:

Force = Pressure × Area

Given: - Area of the desk = 60 cm × 1 m = 60 cm × 100 cm = 6000 cm² = 0.6 m × 1 m = 0.6 m² - Atmospheric pressure = 700 mmHg

Converting Atmospheric Pressure to Standard Units

First, we need to convert the atmospheric pressure from mmHg to standard units (Pascals). The conversion is as follows:

1 mmHg = 133.322 Pa

So, atmospheric pressure = 700 mmHg × 133.322 Pa/mmHg = 93,325.4 Pa

Calculating the Force Exerted by the Air

Now, we can calculate the force exerted by the air on the desk using the formula:

Force = Pressure × Area

Substituting the values: Force = 93,325.4 Pa × 0.6 m² = 55,995.24 N

Therefore, the force exerted by the air on the desk is approximately 55,995.24 Newtons.
