The power of the magnet is determined by the force of the magnetic field it creates.
Ω = 2000 rpm, initial angular speed.
![\omega = (2000 \, \frac{rev}{min} )*(2 \pi \, \frac{rad}{rev} )*( \frac{1}{60}\, \frac{min}{s} ) = 209.4395 \, \frac{rad}{s}](https://tex.z-dn.net/?f=%5Comega%20%3D%20%282000%20%5C%2C%20%5Cfrac%7Brev%7D%7Bmin%7D%20%29%2A%282%20%5Cpi%20%5C%2C%20%5Cfrac%7Brad%7D%7Brev%7D%20%29%2A%28%20%5Cfrac%7B1%7D%7B60%7D%5C%2C%20%5Cfrac%7Bmin%7D%7Bs%7D%20%29%20%3D%20209.4395%20%5C%2C%20%5Cfrac%7Brad%7D%7Bs%7D%20)
t = 30 s, the time for the wheel to come to rest.
Calculate the angular deceleration, α.
w - αt = 0
(209.4395 rad/s) - (α rad/s²)*(30 s) = 0
α = 6.9813 rad/s²
The angular distance traveled, θ, is given by
ω² - 2αθ = 0
θ = ω²/(2α)
= 209.4395²/(2*6.9813)
= 3141.6 rad
The number of revolutions is
3141.6/(2π) = 500
Answer: 500 revolutions
35m/s is meters per second.
35x35=1225
it will have gone a total of 1225 meters on thirty five seconds
Answer:
C, H, N, O, P, S
Explanation:
carbon, hydrogen, oxygen, phosphorus, and sulfur are the 6 most common in biomolecules
So I’m gonna answer the first question on the second page:
For P the force is friction and for Q the force is forward thrust resultant force
