Answer:
here`s your answer
Winds often slow down during an eclipse as the atmosphere temporarily settles. Heating causes the atmosphere to mix and bubble, just like a pot of water on the stove. As it warms, the water level in the pot rises because warm objects, including water, expand. In the case of the atmosphere, it also expands when heated.

Answer:
2.5kN.m
Explanation:
Torque is directly proportional to pitch diameter
= Ta/Tb= Da/Db
=120/Tb= 0.25/0.5
Tb= 2.469kN.m approx 2.5kN.m
Answer:
Expression for angular resolution is;
θ = 1.22π/d
a) 0.85 light year
b) 2.15 x 10³ m
Explanation:

Answer:
Explanation:
mass of airplane, m = 12000 kg
altitude, h = 10 km = 10,000 m
velocity, v = 175 m/s
(a) Angular momentum
L = m x v x h x Sin 90
L = 12000 x 10,000 x 175
L = 2.1 x 10^10 kg m^2/s
(b) As there is no external torque, so the angular momentum remains constant.
Answer:
17×10² km/h
10×10² mph
east to west
Explanation:
Circumference of Earth
Speed = Distance / Time
Converting to mph
The velocity of the plane must be 17×10² km/h or 10×10² mph
The plane must fly east to west
