Intrapleural pressure is Negative during expiration. 

Intrapleural pressure is the air pressure in the pleural cavity and also exists between visceral and parietal pleurae. This pressure majorly depends on ventilation phase, the volume of the intrapleural cavity and atmospheric pressure. During expiration, the Intrapleural pressure in the pleural cavity becomes less negative which is commonly known as negative pressure.

A student named Janine says that the measure of side b is 64 ft. Please state whether this is correct or incorrect. If this is i
kolezko [41]

The measure of side b as 64 ft is incorrect. The accurate measure would be 8 ft.

According to the Pythagorean theorem, the square of the hypotenuse of a right-angle triangle is the sum of squares of the opposite and the adjacent sides. Mathematically:

hypotenuse^2 = opposite^2 + adjacent^2

In this case, the hypotenuse = 10 ft, the opposite = 6 ft and the adjacent = b

Hence,

b^2 = 10^2 - 6^2

       = 100 - 36

          = 64

b = √64

     = 8 ft

Thus, the side b is 8 ft and not 64 ft.
