When i listen to music on my hi-fi (which is connected to my pc)
the sound changes whether my light is on or off.
Its seems that the sound level rises as my light is turned off.
I have a theory that it could be because the light waves interfear with the sound waves.
Therefore if there is no light, then sound will distort less.
But---- you will normally turn off your light in a room when your to go to bed. so is it possible that my brain believes that im going to sleep so it rises my sense? or something similar to this.

I would like to hear what you think~

Find the exact length of the interval [a,b] for ln^2(x)-2ln(x)-4=0.

I just need help on it because i don't understand what i need to do.

I feel like a weirdo for being sad about his passing... but he was like a super hero ;O) He was kinda invincible... then again I knew if he died, he'd go out with a bang.

If you had one positive charge +q1 and one negative charge -q2 and suppose we place a third charge along the line between the two charges. Zone 1 is left of the positive charge. Zone 2 is between the positive charge and the negative charge. Zone 3 is right of the negative charge. This third charge can be in equilibrium if the electric force from the positive can balance the electric force from the negative charge. Than how would you consider the following statements??

True or False -- A negative charge placed in Zone 2 can be in equilibrium.

True or False -- A negative charge placed in Zone 1 can be in equilibrium.

True or False -- A positive charge placed in Zone 2 can be in equilibrium.

True or False -- A positive charge placed in Zone 3 can be in equilibrium.

True or False -- A negative charge placed in Zone 3 can be in equilibrium.

True False A positive charge placed in Zone 1 can be in equilib

why is it that in this equation d(f) = 4f+130, 130 is the y-intercept and 4 is the slope, yet in another equation in the "y=mx+b" form like y=3x+10, y is the y intercept, and 3 is the slope? That just confuses me even more

It is common these days to see news stories about how to save fuel by changing your driving habbits. One of the main ways is to "avoid rapid starts and stops." I can see why rapid starts require more energy, but how does stopping the car briskly also use more energy?

Whether the car's momentum is lost through friction with the air and engine, or through friction with the brake pads, I can't see how it would make any difference.
