High speed winds will blow in more air over the roof

Answer 2

(c).If a statement are demonstrated, "High speed winds will blow in more air over the roof.

Explanation:

• The force on the roof is, According to Bernoulli's principle when the more speed wind blows over the roof.
• The air pressure above the roof becomes less. hence the higher pressure below the roof lifts the roof and it may be blown by the wind.
• They will reduce the air pressure above the roofs. and if the roofs of houses are week, then higher air pressure from below lift up the roofs which can then be blown away by the fast winds.
