<span>Wind is nature's way of balancing the temperature between hot and cold. Wind always flows from heat to cool. When night falls, the air cools. And since it gets cooler at night it reverses.</span>
Independent, and inverse means if one variable increases then the other decreases, direct is when they both go up or down together.
Answer:
Explanation:
We shall represent all the forces in vector form .
Force of 95 pounds
F₁ = 95cos100 i + 95sin100j
= -16.5 i +93.55 j
force of 75 pounds
F₂ = 75cos200 + 75sin200j
= -70.47 i - 25.65 j
force of 146 pounds
F₃ = 146cos300 i + 146sin300j
= 73i -126.44 j
Resultant force
R = F₁+ F₂ + F₃
= -16.5 i +93.55 j -70.47 i - 25.65 j +73i -126.44 j
= -13.97 i - 58.54 j
Magnitude of R = √ ( 13.97² + 58.54² )
= 60.18
If Ф be angle of resultant with axis
tanФ = - 58.54 / -13.97
Ф = 76.57 + 180 = 256.57 , because both x and y components are negative. So the resultant will be in third quadrant.
The speed of sound in gases is represented mathematically as:
v(sound) = √γRT/M
where γ = adiabatic constant which is the ratio of the heat capacities at constant pressure and constant volume; Cp/Cv
R = gas constant
T = temperature
M = molar mass of the gas
Hence, the speed of sound in gas is directly proportional to the square root of temperature.
Ans: c) temperature
