A friend in your class tells you that she never uses hints when doing her Mastering homework. She says that she finds the hints
helpful, but when the hint asks another question it increases the chance that her score on the problem will go down. She feels like it isn't worth the risk.You reassure her that there is nothing to fear about opening a hint that asks a question. Which of the following are good reasons for your friend not to worry? A. The only way to lose additional partial credit on a hint is by using the "give up" button or entering incorrect answers. Leaving the question blank will not cost you any credit.
B. As an incentive for thinking hard about the problem, your instructor may choose to apply a small hint penalty, but this penalty is the same whether the hint simply gives information or asks another question.
C. Getting the correct answer to the question in a hint actually gives you some partial credit, even if you still can't answer the original question.
D. None of the above.
When you answer a question you lose partial credits only when you enter incorrect answers or give up the questions, you never lose credits for leaving it blank
Therefore when reviewing the different alternatives you give the correct one is A
light and radiation is able to experience by an observer watching the explosion from the vacuum.
<u>Explanation:</u>
Basically in the nuclear explosion, there will be an enormous of energy released as noise, heat, visible light, radiation and atmospheric wave.
Usually sound and wave propagate through medium but in vacuum, there will be no medium to transfer this type of energy. so there is no chance of sound and wave transfer.
Light and radiation travel in vacuum because they didn't need the medium to transfer .
