Harriet is told by her doctor that her heart rate is 70.0 beats per minute. If Harriet's average blood flow in the aorta during systole is 1.5*10^ -2 m/s , what is the wavelength of the waves of blood in Harriet's aorta, created by her beating heart?

12.9 mm

Explanation:

From v = fλ where v = speed of wave = blood flow rate = 1.5 × 10⁻² m/s and f = frequency of wave = heart rate = 70 beats per minute = 70/60 beats per second and λ = wavelength of waves in Harriet's aorta.

λ = v/f = 1.5 × 10⁻² m/s ÷ 70/60 beats per second

  = 6 × 1.5 × 10⁻²/7  

  = 1.29 × 10⁻² m

  = 12.9 mm

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
