Verified Solution4 OptionsUpdated: October 2026👁️1 View
Share:
- 1During a windstorm, the atmospheric pressure above the roof is significantly higher than below the roof.
- 2High-velocity winds create a low-pressure region above the roof, making it lower than the pressure below the roof.✓
- 3High-velocity winds exert only a horizontal tangential force on the roof surface.
- 4High-velocity winds cause a sudden increase in the density of the air above the roof.
Correct answer
High-velocity winds create a low-pressure region above the roof, making it lower than the pressure below the roof.
