A desktop has dimensions 1.5 meters by 1.0 meter. How many newtons of force does the atmosphere exert on the top of this desk at sea level? (Atmospheric pressure = 1.01 × 10⁵ N/m²)
Correct Answer
151,500 N
Explanation
First, calculate the area: 1.5 m × 1.0 m = 1.5 m². Then multiply area by pressure: 1.5 m² × 101,000 N/m² = 151,500 N.
