Some people believe the big bang, that from the reactions of objects in space created the earth and stuff, but yet don't believe that there was a god that had something to do with it. If you believe in the big bang, what created that stuff, which created that stuff, to have a reaction to create the earth and stuff. Why don't people notice how magical/unbelievable for a big solid thing (watermelon) to grow from a little tiny black seed, or how another creature is made, from inside a human, thats nothing but guts and meat in the inside!

If you were MacGuyver what would be the simplest method using everyday items (if even possible)? I read one guy's article about a homemade battery charger he made using wall power, a lightbulb as a resistor, and some other house junk. It was pretty innovative.

and I take a cherry and move it from equator to the pole.
It does not require any force or work, does it?

And then moment of inertia of the Earth (with the cherry) will decrese, and the speed of rotation will increase accordingly.

Will kinetic energy of roatation of Earth (with the cherry) increase, remain the same, or decrese?

_5_ indicates 5 as a sub-number. ^2^ indicates 2 as a power-number. In this case, the following equation would read: log base 5 of x-squared = the square of log base 5 of x.


log_5_(x^2^) = [log_5_(x)]^2^

Solve for x. I cannot do it, I admit defeat.

My question is, if you are taking a tablet for lets say depression, and the make you are given by the pharmacist is different then is there a chance the tablet could be different or because it is the same name of tablet then should it be the same mixture, a baked bean changes per brand so does a tablet.?

Also if you do take tablets then do you ever find your body needs to adapt to a new brand, or do you notice nothing?

I'm a little rusty with integration by parts. I'm able to do the first half of this problem. Here's what i have so far:

u = arcsin x; dv = dx; du = 1/√(1-x²) dx; v = x, so

∫ u dv = uv - ∫ v du
∫ arcsin(x) dx = x*arcsin(x) - ∫ x/√(1-x²) dx
The second integral ∫ x / √(1-x²) dx is where I'm lost. Can someone continue with this integral?
