Answer: In order to compensate for the low partial pressure of oxygen at altitude, the human body undergoes a number of physiological changes. A vital component in this process is the increase in the concentration of circulating haemoglobin. The role of HIF‐1α, erythropoietin and red blood cells in this acclimatisation process is described, together with the fall in plasma volume that increases the concentration of haemoglobin in the early stages of hypoxic exposure.
Explanation:
Solution for the problem:
w = h / p
Where:
Wavelength = w
h = Planck's constant = 6.626e-34J*s
p = momentum = m * v
m = mass = 45.9g (1kg / 1000g) = .0459 kg
v = velocity = 66m/s
p = m * v = .0459 kg * 66m/s = 3.0294 N *s
w = h / p = (6.626e-34J*s) / 3.0294 N *s = 2.76e-34 m
