We have that the speed over the ground of a mosquito flying 2 m/s relative to the air against a 2 m/s headwind is
X=0m/s
From the question we are told that
mosquito flying 2 m/s
against a 2 m/s headwind
Generally
The speed over the ground is the Flight Speed minus resistance speed
Generally the equation for the speed over the ground is mathematically given as
X=Flight Speed-resistance speed
Therefore
X=2-2
X=0m/s

To solve this problem it is necessary to apply the concepts related to heat exchange in the vegetable and water.
By definition the exchange of heat is given by

where,
m = mass
c = specific heat
= Change in temperature
Therefore the total heat exchange is given as


Our values are given as,
Total mass is
= 200lb ,however the mass of solid vegetable and water is given as,



Replacing at our equation we have,



Therefore the heat removed is 22411.2 Btu
Answer: it would be A
Explanation: how are we to measure the air of a square mile
