Answer:
(a) 17.37 rad/s^2
(b) 12479
Explanation:
t = 95 s, r = 6 cm = 0.06 m, v = 99 m/s, w0 = 0
w = v / r = 99 / 0.06 = 1650 rad/s
(a) Use first equation of motion for rotational motion
w = w0 + α t
1650 = 0 + α x 95
α = 17.37 rad/s^2
(b) Let θ be the angular displacement
Use third equation of motion for rotational motion
w^2 = w0^2 + 2 α θ
1650^2 = 0 + 2 x 17.37 x θ
θ = 78367.87 rad
number of revolutions, n = θ / 2 π
n = 78367.87 / ( 2 x 3.14)
n = 12478.9 ≈ 12479
I think the correct answer from the choices listed above is option A. The rent is an<span> example of a monthly fixed cost for a sandwich shop. It is a fixed cost since you are required to pay for it per month. Hope this answers the question. Have a nice day.</span>
Answer:
3 electrons from nitrogen and 3 from carbon while carbon already has a lone pair along with a negative charge (called cyanide)
Answer:
Frequency
Explanation:
The frequency ( ) of a wave is the number of waves passing a point in a certain time.
If the vertical component is 29.6 m/s down, and the horizontal component
is 54.8 m/s parallel to the surface, then the magnitude of the slanty vector is
√(29.6² + 54.8²) = √(876.16 + 3003.04) = √3879.2 = 62.28 m/s .
That's 139 mph ! Wow !
