Check Mark

Answer to Problem 84P

The radial acceleration is 90g.

Explanation of Solution

The angular speed of centrifuge is 1.0×103rev/min and the radius of rotor is 8.0cm.

Write the relation between the radial acceleration and the angular speed.

ar=ω2r

Here, the radial acceleration is ar, angular speed is ω, and the radius of rotor is r.

Conclusion:

Substitute 1.0×103rev/min for ω and 8.0cm for r in the above equation to find ar.

ar=(1.0×103rev/min(rad1rev)(1min60s))2(8.0cm(1m100cm))(g9.80m/s2)=(1.09×104)(0.0082)g=90g

Therefore, the radial acceleration is 90g.

Answer to Problem 84P

The net force is 7.9×1011N.

Explanation of Solution

The angular speed of centrifuge is 1.0×103rev/min, radius of rotor is 8.0cm, and the mass of blood cell is 9.0×1014kg.

Write the equation for net force.

Fnet=mar

Here, the net force is Fnet, mass of red blood cell is m.

Conclusion:

Substitute 9.0×1014kg for m and 90g for ar in the above equation to find Fnet.

Fnet=(9.0×1014kg)(90g(9.8m/s2g))=7.9×1011N

Therefore, the net force is 7.9×1011N.

Answer to Problem 84P

The net force is 7.9×1011N.

Explanation of Solution

The angular speed of centrifuge is 1.0×103rev/min, radius of rotor is 8.0cm, and the mass of blood cell is 9.0×1014kg.

Write the equation for net force.

Fnet=mar

Here, the net force is Fnet, mass of red blood cell is m.

Conclusion:

Substitute 9.0×1014kg for m and 90g for ar in the above equation to find Fnet.

Fnet=(9.0×1014kg)(90g(9.8m/s2g))=7.9×1011N

Therefore, the net force is 7.9×1011N.

(c)

To determine

The net force on the virus particle.

(c)

Expert Solution

Answer to Problem 84P

The net force is 4.4×1018N.

Explanation of Solution

The angular speed of centrifuge is 1.0×103rev/min, radius of rotor is 8.0cm, and the mass of virus is 5.0×1021kg.

Write the equation for net force.

Fnet=mvirusar

Here, the mass of virus is mvirus.

Conclusion:

Substitute 5.0×1021kg for mvirus and 90g for ar in the above equation to find Fnet.

Fnet=(5.0×1021kg)(90g(9.8m/s2g))=4.4×1018N

Therefore, the net force is 4.4×1018N.

Answer to Problem 84P

The radial acceleration is 5.0×105g.

Explanation of Solution

The angular speed of centrifuge is 75,000rev/min and the radius of rotor is 8.0cm.

Write the equation for net force.

Write the relation between the radial acceleration and the angular speed.

ar=ω2r

Conclusion:

Substitute 75,000rev/min for ω and 8.0cm for r in the above equation to find ar.

ar=(75,000rev/min(rad1rev)(1min60s))2(8.0cm(1m100cm))(g9.80m/s2)=(61.62)(0.0082)g=5.0×105g

Therefore, the net force is 5.0×105g.
