Answer:
Explanation:
1 mile=5280 ft
1 hour=3600 seconds
Changing speed from mi/h to ft/s
Time of flight,
From fundamental kinematics equations
where g is acceleration due to gravity whose value is taken as 32.2 ft/s2 and h is the distance
By substitution
The correct answer to the question is : 4427.75 J.
EXPLANATION :
As per the question, the mass of the nitrogen gas m = 22.25 gram.
The latent heat of vaporization of nitrogen
As per the question, the nitrogen gas will condense. During condensation, the nitrogen gas will lose or release heat equal to its latent heat.
Hence, the heat released by nitrogen gas Q =
= 22.25 × 199.0 J
= 4427.75 J.
Hence, the amount of heat released will be 4427.75 J.

When energy increase the wavelength decreases and vice versa.
Answer:
c. Line - voltage thermostats and controls are not as sensitive as low - voltage thermostats.
Explanation:
Line voltage thermostat is a regulator which senses the temperature and maintains it to keep the desired level of the voltage. The license in required for the electricians to work on the voltage control wirings. There is technical aspects which an electrician must understand before working on the circuits and voltage lines.
