Ok, here's the question....
"Is the force of gravity stronger on a crumpled piece of paper than it is on an identical piece of paper that has not been crumpled?"

If I had to guess, I'd say it's the same on both, but I could be wrong. Can anyone help explain this to me if I'm wrong?

I am trying to solve measurement equations problems by using the five steps in solving a measurement equation. I am helping a fourth grader with math problems. The problems are coming from the A Beka Book Arithmetic 4 by Judy Howe.

The hair on your body usually stops groing when it reaches a certain length. But when you shorten it, it grows back. How can your body tell how long your hair is, seeing as your hair has no nerves?

Are you going to watch for it? If so, check out Heavens Above.com for trajectory and exact times. It is pretty cool and tonight it is supposed to be brighter than the brightest star.

I thought that blastocysts at the 16 cell stage can replace any stem cell that is taken away. So, couldn't scientists just take one stem cell and let the rest grow to form a baby? Or, is there something wrong with my information?

Can anyone help me think of a physics lab that is not too complicated something that would have tools a high school might have for measuring. That involves the topic of weightlifting/fitness. I cannot have it be TOO simple because it needs to be a major project but I need to measure something and have many people test it and have insturments to measure the variable. i REALLY appreciate it thank you!

This is concerning the phototropism of plant. It is known that plant will grow towards the direction of unlateral light . How about we design two experimental set-ups, one placing a unilateral light source with a high light intensity and the other with a lower light intensity, what would happen to the plant?

HOW would you separate the components of a mixture of ......benzoic acid and Na2SO4 and recover the two separated substances???


When

SOLUBLE IN:
Benzoic Acid
.........cold water = NO
.........hot water = YES
.........3M HCl = NO
.........3M NaOH = Yes
Mg(OH)2
.........cold water = NO
.........hot water = NO
.........3M HCl = Yes
.........3M NaOH = NO


Na2SO4
.........cold water = YES
.........hot water = YES
.........3M HCl = YES
.........3M NaOH = Yes

Zn(OH)2
.........cold water = NO
.........hot water = NO
.........3M HCl = YES
.........3M NaOH = Yes

Could you separate the components of a mixture of benzoic acid, Mg(OH)2 and Na2SO4 by using only cold water and 3M HCl ??? How could I do this???
