Answer:
(a) Rate of heat transfer = 34.65 W/m
(b) quality of outlet of pipe x = 0.967
(c) Temperature of outer surface of insulation, T₂ = U1.157°C
Yes it is safe to touch, (But gentle touch)
Explanation:
Detailed explanation is given in the attach document.
Given :
Capacitor , C = 55 μF .
Energy is given by :
.
To Find :
The current through the capacitor.
Solution :
Energy in capacitor is given by :
Now , current i is given by :
![i=C\dfrac{dv}{dt}\\\\i=C\dfrac{d[603.02cos(337t)]}{dt}\\\\i=-55\times 10^{-6}\times 603.03\times 337\times sin(337t)\\\\i=-11.18\ sin(337t)](https://tex.z-dn.net/?f=i%3DC%5Cdfrac%7Bdv%7D%7Bdt%7D%5C%5C%5C%5Ci%3DC%5Cdfrac%7Bd%5B603.02cos%28337t%29%5D%7D%7Bdt%7D%5C%5C%5C%5Ci%3D-55%5Ctimes%2010%5E%7B-6%7D%5Ctimes%20603.03%5Ctimes%20337%5Ctimes%20sin%28337t%29%5C%5C%5C%5Ci%3D-11.18%5C%20sin%28337t%29)
( differentiation of cos x is - sin x )
Therefore , the current through the capacitor is -11.18 sin ( 377t).
Hence , this is the required solution .
Answer:
As the temperature of a thermal radiator is increased
Group of answer choices
- the object appears redder.
- the object appears bluer.
- the object emits more power for the same area.
- the object emits less power for the same area.
- the object expands to keep the same power per units area.
<em>When the temperature of a thermal radiator increases ;</em>
- <em>the object emits more power for the same are</em>
- <em>the object becomes bluer</em>
Explanation:
Thermal radiation involves the transfer of heat between molecules of two substances without direct contact with each other. When a body is heated to a given temperature it begins to emit light which is transferred to nearby objects as thermal radiation. The medium through which the heat is transferred could be liquid, solid, or in a vacuum.
<h3>How temperature affects thermal radiation.</h3>
Temperature determines the amount of heat that is been radiated from a body. An increase in temperature would increase the thermal radiation of the body. The increase in the heat radiation results to increase in the thermal energy of the body. Also when a body is heated it tends to be bluer than a cool object, this is caused by the rapid movement of the molecules.
Therefore When the temperature of a thermal radiator increases ;
- the object emits more power for the same are
- the object becomes bluer
