An increase in a sound's pitch corresponds to an increase in the frequency!
Well he could remove the drawers to make it lighter, which causes less friction
Answer: 8.8e-3 rad/s², 0.0 m/s²
Explanation:
R = 35 / 2 = 17.5 m
a = 2.3 m/s / 15 s = 0.1533333... m/s²
α = a/R = 0.1533333/17.5 = 0.0087619... ≈ 8.8e-3 rad/s² ◄(a)
at maximum speed, no more acceleration in either tangential or angular
α = a = 0.0 rad/s² or m/s² ◄(b)
Answer = C
It blows towards the poles from the sub-tropical high pressure areas
