The correct answer is the last one:
A and C are different elements, while D is an isotope of C.
In fact, A and C are different elements, because they have a different number of protons in the nucleus (A has 3 protons, while C has 4 protons). Instead, D and C are the same element (they both have 4 protons in the nucleus), but they are different isotopes since they have a different number of neutrons (D has 4 neutrons while C has 3 neutrons)
Answer:
Explanation:
Given that
Emissivity of surfaces(∈) = 1
We know that heat transfer between two surfaces due to radiation ,when both surfaces are black bodies
So now by putting the values
So rate of heat transfer per unit area

The time in air is determined by the initial vertical velocity. This is because, the steeper the launch angle the larger the vertical velocity component, that causes the launch angle to increase the time in air.
I did Physics a while ago but I believe my answer is correct. (:
Hope this helps! (:
