Honestly i need help in this my self but i hope that this model can help!
Answer :
(a) The angular speed of this bacterial motor is ![1.6\times 10^3s^{-1}](https://tex.z-dn.net/?f=1.6%5Ctimes%2010%5E3s%5E%7B-1%7D)
(b) The time taken by the motor to make one revolution is ![3.9\times 10^{-3}s](https://tex.z-dn.net/?f=3.9%5Ctimes%2010%5E%7B-3%7Ds)
Explanation :
(a) To determine the angular speed of this bacterial motor.
Angular speed : It is defined as the rate at which an object changes its angle.
Formula used :
![\omega=\frac{v}{r}](https://tex.z-dn.net/?f=%5Comega%3D%5Cfrac%7Bv%7D%7Br%7D)
where,
= angular speed
v = tangential speed = ![2.1\times 10^{-5}m/s](https://tex.z-dn.net/?f=2.1%5Ctimes%2010%5E%7B-5%7Dm%2Fs)
r = radius = ![1.3\times 10^{-8}m](https://tex.z-dn.net/?f=1.3%5Ctimes%2010%5E%7B-8%7Dm)
Now put all the given values in the above formula, we get:
![\omega=\frac{2.1\times 10^{-5}m/s}{1.3\times 10^{-8}m}](https://tex.z-dn.net/?f=%5Comega%3D%5Cfrac%7B2.1%5Ctimes%2010%5E%7B-5%7Dm%2Fs%7D%7B1.3%5Ctimes%2010%5E%7B-8%7Dm%7D)
![\omega=1.6\times 10^3s^{-1}](https://tex.z-dn.net/?f=%5Comega%3D1.6%5Ctimes%2010%5E3s%5E%7B-1%7D)
Thus, the angular speed of this bacterial motor is ![1.6\times 10^3s^{-1}](https://tex.z-dn.net/?f=1.6%5Ctimes%2010%5E3s%5E%7B-1%7D)
(b) to determine the time taken by the motor to make one revolution.
Formula used :
![T=\frac{2\pi}{\omega}](https://tex.z-dn.net/?f=T%3D%5Cfrac%7B2%5Cpi%7D%7B%5Comega%7D)
where,
T = time
Now put all the given values in this formula, we get:
![T=\frac{2\times 3.14}{1.6\times 10^3s^{-1}}](https://tex.z-dn.net/?f=T%3D%5Cfrac%7B2%5Ctimes%203.14%7D%7B1.6%5Ctimes%2010%5E3s%5E%7B-1%7D%7D)
![T=3.9\times 10^{-3}s](https://tex.z-dn.net/?f=T%3D3.9%5Ctimes%2010%5E%7B-3%7Ds)
Thus, the time taken by the motor to make one revolution is ![3.9\times 10^{-3}s](https://tex.z-dn.net/?f=3.9%5Ctimes%2010%5E%7B-3%7Ds)
