How does quantum theory explain blackbody radiators? A. As the radiator is heated, it can have only certain specific
temperature values.
B. As heat is added, the radiator emits photons across a wide range
of visible-light frequencies.
O C. Raising the temperature of the radiator causes more photons of a
few possible energies to be emitted.
D. Raising the temperature results in the radiator giving off photons
of high-energy ultraviolet light.

1 the 4 is sig

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
