A home was designed to have passive solar energy to heat and cool the home using purposeful construction and materials. The model for passive solar design is shown here. Evaluate which statements are accurate about light energy and passive solar design.
Select ALL that apply.
A)
B)
C)
The floor materials should absorb light to allow for heating of the home.
The windows should transmit light to allow for light to illuminate the
home and heat the interior,
The walls should be opaque to prevent the transmission of light so that the
home is not overheated
The roof should be translucent to allow for the maximum amount of light
to enter the home during all seasons of the year.
The top of the roof should block light or reflect light so that direct solar
radiation is not entering and heating the home in the summer.

E)

Cobalt-60 is an artificial radioisotope that is produced in a nuclear reactor and is used as a gamma-ray source in the treatment of certain types of cancer. if the wavelength of the gamma radiation from a cobalt-60 source is 1.00 × 10-3 nm, calculate the energy of a photon of this radiation.

The earth's moon is unusually large. two popular theories of the moon's origin include the "sister world" hypothesis, which states that the moon formed from the same materials as the earth, near enough to the earth that they fell into orbit around each other. a second theory is the "capture" hypothesis, in which the moon formed elsewhere in the solar system, and the earth's gravity pulled it into its orbit. studies of what the moon is made of indicate that some of its materials had to come from the earth or from the same area of the solar system where the earth had formed. at the same time, the moon does not contain much of the material that makes up the earth's core, so the moon could not have formed from the same materials as the earth. how do the two facts above affect the described theories of the moon's origin? a. they show that scientists will never agree on where the moon came from. b. they show that more experiments on moon formation need to be done. c. they show that no theory accounts for the existence of the moon. d. they show that neither theory is complete and entirely correct.

At a temperature of 393 k, the temperature of a sample of nitrogen is 1.07 atm what will the pressure be at a temperature of 478 k
