Answer:
Yes, correct
Explanation:
velocity, v = 470 m/s
radius, r = 0.15 m
The radial acceleration is the centripetal acceleration which always acts towards the centre of the circular centrifuge.
The formula for the centripetal acceleration is given by
[tex]a =\frac{v^{2}}{r}[/tex]
[tex]a =\frac{470^{2}}{0.15}[/tex]
a = 1472666.667
a = 150272.1 g
According to the question, we can get the acceleration as mentioned. So the claim is correct.
Answer:
no, the claim is not correct
Explanation:
You are working in a biology lab and learning to use a new ultracentrifuge for blood tests. The specifications for the centrifuge say that a red blood cell rotating in the ultracentrifuge moves at 470 m/s and has a radial acceleration of 150,000 g's (that is, 150,000 times 9.8 m/s2). The radius of the centrifuge is 0.15 m. You wonder if this claim is correct.
centripetal force is the force that is needed to keep an object undergoing a circular motion in a circular path .
a centripetal force is responsible for centripetal acceleration
a=v^2/r
a=470^2/0.15
a=1472666.66m/s^2
for the radial acceleration
150000*9.8
1470000m/s^s
the two differ by
da=1472666.66m/s^2-1470000m/s^2
da=2666.66m/s^2
therefore the claim is not correct
