Answer:
The claim is false and violate the zeroth law of thermodynamics.
Explanation:
Zeroth law of thermodynamics refers to thermal equilibrium among elements. It states that elements which different temperatures will reach the same temperature at the endgame if they are close enough to interact each other. This temperaure is called <em>equilibrium temperature and it is always a intermediate value between the element with highest temperature and the element with the lowest one. So there is no way </em> a cup of cold coffee on a table can warm up to 80°C picking up energy from the surrounding air at 25°C because the cup can only reach a temperature closer to the surrounding air temperature which will be the equilimbrium temperature for that case.
Do you know anything about a Hummingbird kit and know how to code it?
Answer:
A classical Trombe wall, also generically called a vented thermal storage wall, has operable vents near the ceiling and floor levels of the mass wall that allow indoor air to flow through them by natural convection. As solar radiation heats the air trapped between the glass and wall and it begins to rise.
Answer: Forward So it's D
Answer:
d=4.63 mm
Explanation:
Given that
Load ,P = 10,100 N
FOS = 1.5
Sy= 900 MPa
Therefore the working stress will be
Lets take the diameter of wire = d mm
The area
For design purpose
A=16.83 mm²
d=4.63 mm
