Answer:
Also we know that for cyclic process change in internal energy is always ZERO
Explanation:
First gas is compressed isobarically such that its volume is half of initial volume
So its temperature is also half
So heat given in this process is given as
for diatomic gas we have
so we will have
Now in adiabatic process heat is not transferred
so in this process
so we have
Now it is again reached to original pressure
so temperature will become initial temperature
so heat given in that part
here we know that
So total heat given to the system is
Also we know that for cyclic process change in internal energy is always ZERO
Answer:
A time period is denoted by 'T' . It is the time to complete one cycle of vibration. As the frequency of a wave increases, the time period of the wave decreases. The unit for time period is 'seconds

Answer:
(a) Q = 142.67 W
(b) Basal Metabolic Rate = 178.33 W
Explanation:
(a)
We can find the heat radiated by the person by using Stefan-Boltzman's law:
where,
Q = heat radiated per second = ?
σ = Stefan-Boltzman Constant = 5.6703 x 10⁻⁸ W/m².k⁴
A = Surface Area = 2 m²
T = Temperature of Skin = 30° C + 273 = 303 k
Ts = Temperature of room = 18° C +273 = 291 k
Therefore,
![Q = (5.6703\ x\ 10^{-8}\ W/m^2.k^4)(2\ m^2)[(303\ k)^4-(291\ k)^4]](https://tex.z-dn.net/?f=Q%20%3D%20%285.6703%5C%20x%5C%2010%5E%7B-8%7D%5C%20W%2Fm%5E2.k%5E4%29%282%5C%20m%5E2%29%5B%28303%5C%20k%29%5E4-%28291%5C%20k%29%5E4%5D)
<u></u>
<u>Q = 142.67 W</u>
<u></u>
(b)
Since the heat calculated in part (a) is 80 percent of basal metabolic rate. Therefore,
<u>Basal Metabolic Rate = 178.33 W</u>
