Answer:
Option B. They use thermal updrafts to stay aloft
Explanation:
The sunlight warms the surface of the earth during noon and morning time and when this warming of the Earth's surface is not evenly done or uniform then this gives rise to the thermals. These are the rising air columns and rises when the air nearest to the earth heats up.
This is how some birds like vultures make use of the thermal updrafts to maintain flight.
Pb, if compared to Ca it is less reactive and it is a transition metal, and is highly stable alone.
Answer:
Explanation:
α = (ωf - ωi)/t
acceleration phase
ωf = 132 rev/min (2π rad/rev / 60 s/min) = 4.4π rad/s
α₁ = (4.4π - 0)/20 = 0.22π rad/s²
α₂ = (0 - 4.4π)/40 = - 0.11π rad/s²
α₁/α₂ = 0.22π/- 0.11π = -2
