<span>Radius distance from origin to particle = √ (2²+1²) = √5 m = R
I = MR² = (0.200)(5) = 1.00 kg-m²
Θ = arctan 2/1 = 63.4° = R's angle CCW from horizontal
V = 3.0 m/s
V component that is at 90° to R = 3.0(sin 90°- 63.4°) = 3.0(sin 26.6°) = 1.3433 m/s
w = [V component / R] = 1.3433/√5 = 0.601 rad/s
size of angular momentum of particle relative to origin = Iw = (1.00)(0.601) = 0.601 kgm²/s</span><span>
i hope I'm right</span>
Explanation:
Hipparchus had observed and discovered the precession motion of Earth. Due to the precession the axis of the Earth will gradual shift in a cycle of 25772 years. That means the axis will point towards different stars in the celestial sphere and our pole stars will change.
Because of this change in the axis the apparent position of Sun with respect to the background constellation (sun signs) regresses. Because of which the dates associated with the sun signs will be wrong.
Answer:
I think it's B
Explanation:
sorry if I got it wrong TvT
At 60 mph (26.7 m/s), Johnny Hotfoot slams on the brakes of his car and skids to a stop in 4 s. (A) How fast is the car slowing down? (b) The extent of the skid.
If the car had been traveling at 40.0 m/s, it would have slid 27.2 m.
The frictional force opposes the linear force pulling on the automobile. Consequently, m is the vehicle's mass, an is its acceleration, and c is its coefficient of friction.
The normal force is R.
given the aforementioned variables
Find the length of the skid if the vehicle had been traveling at 40.0 m/s.
The car would have skidded 27.2 meters if it had been driving at 40.0 meters per second.

That's true.
Magnets attract some metals such as iron, nickel, etc.
Hope this helps~
