Ahhh this going to be confusing sorry...
1. α = Δω / Δt = 28 rad/s / 19s = 1.47 rad/s²
2. Θ = ½αt² = ½ * 1.47rad/s² * (19s)² = 266 rads
3. I = ½mr² = ½ * 8.7kg * (0.33m)² = 0.47 kg·m²
4. ΔEk = ½Iω² = ½ * 0.47kg·m² * (28rad/s)² = 186 J
5. a = α r = 1.47rad/s² * 0.33m = 0.49 m/s²
6. a = ω² r = (14rad/s)² * 0.33m = 65 m/s²
7. v = ω r = 28rad/s * ½(0.33m) = 4.62 m/s
8. s = Θ r = 266 rads * 0.33m = 88 m
Answer:
The downwind side of an obstacle such as a ridge. The addition of weight on top of a snowpack, usually from precipitation, wind drifting, or a person. An avalanche that releases from a point and spreads downhill collecting more snow - different from a slab avalanche. Also called a point-release or sluff.
Explanation:
2m/s²
Explanation:
Given parameters:
Radius = 50m
Speed = 10m/s
Unknown:
Acceleration of the cyclist
Solution:
The acceleration of the cyclist is directed inside of the corner because his motion is inward. This is a form of centripetal acceleration;
Centripetal acceleration is given by;
a = 
v is the velocity
r is the radius
a =
= 2m/s²

Answer:
The inductance of this solenoid is 5.51 mH.
Explanation:
Given that,
length of the tube, l = 38 cm = 0.38 m
Diameter of the tube, d = 8.3 cm
Radius of the tube, r = 4.15 cm
The number of turns, N = 555
We need to find the inductance of this solenoid. It is given by the formula as :

So, the inductance of this solenoid is 5.51 mH. Hence, this is the required solution.
