On a normal pool table, we have a series of pockets around a flat table. Suppose you replaced some of the pockets with wormholes in space. Never mind how much this pool table would cost, just suppose it was done. A pool ball could go in one pocket and come flying out of another one somewhere else on the table.

However, Einstein's theories allow for wormholes that move objects in both space and time. Suppose the pool ball re-emerged before it even went in. For a brief moment you have twice as many pool balls as before.

Suppose you angled your shot just right, and your poolball came out on another course and struck its past self so that neither of them entered the pocket. Doesn't that violate the law of conservation of matter? Would I get rich if I had a solid gold cue ball and good skills (double one, sell one of the dupilcates), repeat)? Just curious to see if there is an answer.

Suppose that an algorithm A runs in worst-case time f(n) and that algorithm B runs in worst-case time g(n). Is A faster than B for all n greater than some n0 if g(n) = Ω(f(n)logn) ? Answer either yes, no, or can’t tell and explain why.

I have a quiz tomorrow on molarity and i still don't understand some homework questions.
Please help me solve the following questions.
How many mL of a .5M K2 Cr2 O7 must be evaporated to dryness in order to end up with a 2.948g of solid K2 Cr2 O7.

How many grams of sodium chloride are present in 45mL of .125M NaCl?

How many liters of .5M C6 H12 O6, solution will contain exactly 100g glucose?

What is the molarity of a solution made by dissolving 10.6g of NaCO3 in 400mL of water?

A person mixes 100mL of a .5 M NaOH solution with 150mL of a .3M NaOH solution. What is the molarity of the resulting NaOH solution?

Only the machine happens to touch down on top of your grandmother before your father was born? Wouldn't that mean that you would simply pop out of existence?

However, if you never existed who shot grandma? Therefore, grandma lives, and her grandson builds the time machine and flattens grandma again? Am I right that the result will just be an infinitely looped tragedy?

What is the speed required for an nuetron to cause Nuclear Fission?
____
In order for nuclear fission to occur (the splitting of a atomic nucleus), a free nuetron has to bombard the nucleus, moving at a very high speed. I was wondering, how fast?

A space station is in the shape of a hollow ring with an outer diameter of 150 m. How fast should it rotate to simulate Earth's gravity--that is, so that the force exerted on an object by the outside wall is equal to the object's weight on Earth's surface?

A block of mass(m) is being pulled at a constant speed(v) down a slope that makes an angle(theta) with the horizontal. The pulling force is applied through a horizontal rope, as shown below. If the coefficient of kinetic friction is Uk, find an expression for the rope tension.

Marc attaches a falling 500-kg object with a rope through a pulley to a paddle wheel shaft. He
places the system in a well-insulated tank holding 25 kg of water. When the object falls, it
causes the paddle wheel to rotate and churn the water. If the object falls a vertical distance of
100 m at constant speed, what is the temperature change of the water? (1 kcal = 4 186 J, the
specific heat of water is 4 186 J/kg°C, and g = 9.8 m/s2).

Answer: 4.7 C°

This question has been on my mind for quite a while. Everyone I study with has been wondering where do they go when it rains. Do they stand there, get sick and die? Or do they find a shelter somewhere and stay safe??
