Answer:

Explanation:
=10°C,
=93.33°C
Q=500 btu=527.58 KJ

If we assume that air is ideal gas PV=mRT, ΔU=
Actually this is closed system so work will be zero.
Now fro first law
Q=ΔU=
+W
⇒Q=
527.58 =
m=4.9kg
PV=mRT

Answer:
Limitation in the level of possible accuracy of the that can be obtained to mainly whole degrees
Explanation:
The angle measurement values are located around the circularly shaped bevel protractor to which a Vernier scale can be attached to increase the accuracy of the angle measurement reading
The accuracy of the bevel protractor is up to 5 arc minutes or 1/12° with the space on the Vernier scale having graduations of 1/12°, such that two spaces on the main scale is 5 arc minutes more than a space on the Vernier scale and the dimensions of the coincidence of the two scale will have an accuracy of up to 1/12°
Therefore, whereby the Vernier scale is damaged, the accuracy will be limited to the accuracy main scale reading in whole degrees.
Answer: a) Fd = 3.24 N/m
b) Q = 520 w/m

He probably just like the cool weather or being outside lol
