Suppose you were transported to an alien universe where light traveled instantaneously from place to place (infnite speed). In this universe the relativistic effects of length contraction and time dilation

[a] would be the same as in your present world.

[b] become infnitely more pronounced than they are in your present world.

[c] become less pronounced than they are in your present world.

[d] would not exist.

Solutions

Expert Solution

Light traveling instantaneously means the speed of light is infinity.

In the universe where the speed of light is infinity, the relativistic effects

d) would not exist.

This is because the length contraction relation is

In the limit where c is infinity

Hence

Similarly, the time dilation relation becomes

which means the length doesn't get contracted and the time doesn't get dilated at all.

Suppose you meet an extraterrestrial alien. The alien is doing a research project on the health care system in the United States since the 1960’s. The alien understands that disease exists and that resources are scarce. Explain to the alien the foundational parts of our health care system AND how our health care system has evolved since the 1960’s and why.

Suppose you perform an alien autopsy on a creature from Area 51. You discover that instead of having a sodium/potassium pump, it has a sodium/magnesium pump. It works just the same, but pumps an ion of magnesium in place of each ion of potassium. Will the resting membrane potential (RMP) be more positive or more negative? Will the electrical gradient be larger or smaller? Explain your answer. (Hint: Magnesium has a charge of +2)

If you were flying a model airplane on a wire so that it traveled in a circle around you, would you hear a Doppler shift in the sound from the airplane? Explain. In Olympic sprint events, the sound of the starter gun is sent to individual speakers at each runner’s starting block rather than relying on the sound traveling through the air. Why? Does the speed of sound waves through air depend on the frequency of the sound? Justify or...

Suppose that the Earth was thermally insulated from the rest of the universe so that it was an isolated system. Describe the entropy of the Earth as a function of time. Consider taking two identical ice cubes out of the freezer. You place one in a cup and let it melt; you take the other and smash it with a hammer and then put it in an identical cup and allow it to melt. Compare the entropy changes of the...

The Alien Ethnographer Imagine that you are an ethnographer from a different planet. As part of your alien Ph.D. requirements, you have been sent to earth to conduct an ethnographic study of any “human activity” of your choosing. This activity may be something you are currently witnessing (e.g., behavior in the student center) or something you have witnessed in the past (e.g., a family celebration of a specific holiday). You are to conduct a small ethnographic study of this observed...

About 100 years ago, physicists were working to determine the speed of light. The results of 25 independent measurements gave an average of 299.796 million meters/second with a standard deviation of 0.004 million meters/second. Assume the distribution of measurements was not strongly skewed. What type of inference is most appropriate given the goal of the research? A.Hypothesis test B.Confidence interval C.No inference is needed
