that the Universe's Farthest Galaxy Found is13.23 Billion Light-Years From Earth i thought it was 18 Billion LY away am i wrong?
Another question, since that galaxy is so far away if it were possible to go there could there be life there know or would that galaxy be died?

i'm doing a science fair project and i need to know some background info about plants. The project is to know that affect of different liquids on the plant, but first i must know tha general affect. Anytiing you have to say will really help me out. ^-^

If you shoot a firework into the air and it hits it's maximum height in 7 seconds and explodes sending fragments scattering in horizontal directions all around at a speed of 20 meters per second then (assume that air drag is negligible):

It would only take the fragments 7 seconds to fall right?
A)What will be the acceleration of the fragments as they fall vertically?

B)What is the path of the fragments as they fall to the ground?

C)Why do the fragments follow this path?

Please explain how you figured these out.I'm trying to learn but it's so confusing.

Two thin rectangular sheets (0.06 m* 0.46 m) are identical. In the first sheet the axis of rotation lies along the 0.06 m side, and in the second it lies along the 0.46 m side. The same torque is applied to each sheet. The first sheet, starting from rest, reaches its final angular velocity in 7.4 s. How long does it take for the second sheet, starting from rest, to reach the same angular velocity?

A CD has a mass of 17 g and a radius of 6.0 cm. When inserted into a player, the CD starts from rest and accelerates to an angular velocity of 22 rad/s in 0.88 s. Assuming the CD is a uniform solid disk, determine the net torque acting on it.

My calculus class just covered this topic yesterday, but I don't understand it in the least.....

For example, f(x)=2lnx^3

would you take the derivative of 2 and then the derivative of lnx^3?

if so, then 2 would become zero and the whole thing cancels out?

Any help would be greatly appreciated.

2nd law of thermodynamics says that energy "spreads out" to try to reach equlibrium. My understanding is that it's like a gas which spreads out to fill the room it's in. Then why hasn't the universe reached a state of equilibrium? 2nd law says processes are irreversible. Does physics also say there is reversability in the universe? That's my only explanation.
