For nitrogen to be a liquid, its temperature must be within 12.78 °f of –333.22 °f. the equation |x 333.22 | = 12.78 can be used
2 answers:
The maximum temperature is -320.44 and the minimum temperature is -333.22.
<h3>How is the temperature variation calculated?</h3>In this case, there was an increase of 50 °C in the temperature of this object. We say that the temperature variation suffered by the body was 50°C, and this can be determined mathematically through the difference between the final value and the initial temperature value (60 – 10 = 50).
In this case, we have:

Answer:
The resultant velocity is 86.1 mi/h.
Explanation:
The law of cosines is given by:
Where:
c: is the resultant velocity =?
a: is the velocity of the plane = 75.0 mi/h
b: is the velocity of the wind = 15.0 mi/h
θ: is the angle between "a" and "b"
The angle between "a" and "b" can be found as follows:
Now, by using the law of cosines we have:
Therefore, the resultant velocity is 86.1 mi/h.
The law of sines is:
Where:
γ: is the angle between "b" and "c"
α: is the angle between "a" and "c"
So, if we want to find "c" by using the law of sines, we need to know another angle besides θ (γ or α), and the statement does not give us.
I hope it helps you!
