<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>
Answer:
lose, higher
Explanation:
An aircraft lose altitude when flying from a region of higher temperature to a region of cooler temperature, hence making the reading on the altimeter to be high.

Answer:
24.7 s
Explanation:
Question is appear to be missing. Found it on google:
"a) If there were no air resistance, how long would it take to fall?"
Solution:
We can solve the problem by using the following equation of motion for a uniform accelerated motion:

where
d = -3000 m is the displacement of the raindrop (negative because in the downward direction)
u = 0 is the initial velocity of the raindrop if we assume it starts from rest
t is the time taken for the fall
a = g = -9.8 m/s^2 is the acceleration of gravity
Solving the equation for t, we find:
