In research in cardiology and exercise physiology, it is often important to know the mass of blood pumped by a person's heart in

frez [133]

Answer:

0.05081 kg

Explanation:

$m_1$ = Mass of blood

$v_1$ = 0.435 m/s

$m_2$ = Mass of subject and pallet = 54 kg

$v_2$ = Velocity of subject and pallet = $\dfrac{Distance}{Time}=\dfrac{6.55\times 10^{-5}}{0.16}=0.000409375\ m/s$

In this system the linear momentum is conserved so,

$m_1v_1=m_2v_2\\\Rightarrow m_1=\dfrac{m_2v_2}{v_1}\\\Rightarrow m_1=\dfrac{54\times 0.000409375}{0.435}\\\Rightarrow m_1=0.05081\ kg$

The mass of blood is 0.05081 kg

A piano string having a mass per unit length equal to 5.00× 10⁻³kg / m is under a tension of 1350N . Find the speed with which a

DiKsa [7]

Based on the mass per unit length and the tension, the speed that the wave travels on this string is 519.615 m/s.

<h3>What is the speed?</h3><h3 />

The speed that the wave travels can be found as:

Velocity² = Tension / Mass per length

Solving gives:

Velocity² = 1,350 / 0.005

Velocity² = 270,000

Velocity = √270,000

= 519.615 m/s
