You are an adventurer in War of Warcraft. You come
across two closed treasure chests. One chest is full
of gold and treasure, while the other chest is full of
coal. If you open one chest, the other will disappear.


There are two goblins, one guarding each chest. One
goblin always tells the truth, and the other goblin
always lies. You can only ask one question to one of
the goblins before choosing a chest to open.

What one question can you ask one of the goblins to
find out which chest is full of gold?

Prove that
a^(n) - b^(n) can be expressed as difference of two squares in the form of (c+a-b)^(2) - c^(2), if a^(n) - b^(n) is not of the form of 4t + 2 where t is a rational number.Here "c" is natural number.

In a frictionless system of a block of mass m = 2kg attached to a spring of spring constant k = 8 N/m, the mass is displaced from the equilibrium position by x = 3m and let go with zero initial velocity, v(initial) = 0 m/s.

Answer this question :
Write an expression for the displacement x of the mass from equilibrium as a function of time. Use numerical values wherever possible.

Doesn't a jet engine have a big enough output ratio that it could produce more energy than it consumes? Wouldn't that be the same as perpetual motion?

If you weren't to round it up to 1, you might say that the number 1 is impossible to reach and does not really exist. Maybe I'm overthinking it but I thought it was an interesting question.

For one of my classes in college, I need to make a model of something related to fire safety/physics. I need some info on how to make a model of a sprinkler system (what parts are needed and how to put it together). If anyone knows, or knows a website, please post. OR if you know how to do anything else related to fire safety/physics, please post as well. Thank you!

The years are approximate, but I can't find anything past 2020. The solution is probably so incredibly easy to find out, but I don't know how nor do I have the intrest. Plus I don't want to be wrong.

Also, will Sirius be visible at the same time in Virginia (say 37 degrees north)?

Thanks.
