Radiation

Radiation can be described as the energy in the form of a particular matter or electromagnetic waves traveling in the air and can be in the form of light, sound, and heat. Radiation can be detected through special instruments like X-rays. The radiation from a cooler object is less intense as compared to the radiation from hot objects.

(choose 3 answers) 1- it has been operating for a long time. 2- the properties do not change with time. 3- the property values can be different at different location in the device. 4- the total energy content in the control volume remains unchanged. 5- the rate of energy coming into the system equals to the rate of energy exits the system.
Solar ponds are small artificial lakes of a few meters deep that are used to store solar energy. The rise of heated (and thus less dense) water to the surface is prevented by adding salt at the pond bottom. In a typical salt gradient solar pond, the density of water increases in the gradient zone, as shown, and the density can be expressed as ρ = ρ0√1 + tan2(?/ 4 s/ H) where ? 0 is the density on the water surface, s is the vertical distance measured downward from the top of the gradient zone (s = −z), and H is the thickness of the gradient zone. For H = 4 m, ?0 = 1040 kg/m3, and a thickness of 0.8 m for the surface zone, calculate the gage pressure at the bottom of the gradient zone.
A woman informs an engineer that she frequently feels cooler in the summer when standing in front of an open refrigerator. The engineer tells her that she is only “imagining things” because there is no fan in the refrigerator to blow the cool air over her. A lively argument ensues. Whose side of the argument do you take? Why?
