According to the oxygen-hemoglobin dissociation curve, PO2 in the lungs of 100 mm Hg results in Hb being 98% saturated. At high

Ad libitum [116K]

Answer:

Hb would be 78.4% saturated.

Explanation:

This problem can be solved by using simple unitary method.

At 100 mm Hg pressure of oxygen, Hb is saturated by 98%

So, at 1 mm Hg pressure of oxygen, Hb is saturated by $\frac{98}{100}$ %

Hence, at 80 mm Hg pressure of oxygen, Hb is saturated by $\frac{98\times 80}{100}$ % or 78.4%

Therefore, at 80 mm Hg pressure of oxygen in the lungs, Hb would be 78.4% saturated.

A mass of 2kg has a kinetic energy of 16J.what is the momentum of the body?

juin [17]

Explanation:

mass -2kg

energy -16j

k.e -1/2mv

16j= 1/2×2×V

16× 2/2 =V

16 = V

√16= V

V= 4m/s

Then

momentum=MV

=2×4

=8kgm/s
