Two radio antennas 60m apart broadcast a synchronized signal with a frequency of 100Hz. Imagine that we have a detector 5.0km away from the antennas. At this distance, what is the separation between adjacent bright spots in the interference pattern along a line parallel to the line between the antennas? I need a detailed explanation.

Do you think .9 repeating is 1?

.99999999999999999999999999999...
Do you think this number is really 1? Of course it is not, but when you use the "9 trick" (putting a repeating decimal over 9 to express it as a fraction) it will be 9 over 9, which is actually equal to 1. Of course, this number gets so close to 1, but it never truly reaches 1. What do you say?

Do bigger things decay faster than smaller things?

For example, would a human decay as fast as a cat or fox?
We are trying to decide if zombie cats have a shorter than zombie humans.

Also if you know, does the solanum (zombie virus) have the ability to infect animals or just humans?

Are there studies on fasting and blood chemistry?

There is no doubt that fasting is beneficial, as I've tried it myself. But does the body actually "purge" itself of toxins as we have been told? Are they flushed out of tissues and dumped into the bloodstream? Where do they go? What percentages are excreted from the skin? The bowel? The lungs? The sinuses? Is it even measurable? Are there examples of blood chemistry before, during and after a long fast? Is the blood full of stress-related chemicals before the fast? Does the blood become "dirty" with toxins and perhaps microbes/parasites/pathogens during the cleansing stage (when we experience the headaches, chills, fever, nausea, etc)? Does the blood become "clean" again after the fast has ended? Most importantly, where has this all been proven? Everyone has an opinion, but I'm interested in knowing where I can find the FACTS.

Physics-Oscillatory Problem!?

Two geekie physics students with a combined mass of 146 kg jump into their old car to run out for some late night pizza. The distance between the front and back axles of the car is 2.7 m. When they get in the car, the springs compress a total of 8.9 cm. On their way to the Pizza Hut, when they go over a bump, the car oscillates up and down with a period of 1.7 seconds.

** What is the mass of the car?
