That is a magnetic field.

Math
If you multiply both sides of the ratio by any number, their simplest form will not change. So 3x2=6 10x2=20 6:20 in simplest form is 3:10 Another example is 9:30

Note that is all three laws listed.

1. An object in motion will remain in motion unless acted upon by a net force. 2. Force equals mass multiplied by acceleration. (F=ma) 3. To every action there is an equal and opposite reaction.

Physics
I understand now, thanks.

double?

Physics
Then what is the correct answer?

Physics
A shell is fired horizontally and takes .5 seconds to fall. If its initial speed were doubled, the time it would take to fall would be: .25 seconds I know the answer, but I need an explanation if possible.

Adding Doubles just means adding the same numberr to itself. Like 2+2=4, 3+3=6, So addind doubles to 18 would be 0+0=0, 1+1=2, 2+2=4, and so forth up to 9+9=18. Maybe this will help you solve the problem. I have a work sheet that has Add Doubles to 18 with questions asking how...

The word step is misleading. http://biology.about.com/library/bltranslation.htm How many steps are there in translation? I've been searching and so far I have found a site that says that there are 5 steps, one that says 4 steps, and one that only has three steps.

Give us the figures. Density is equal to mass over volume. D= M --- V To get mass you weigh the object. To get volume you either measure it depending on its shape eg. round, square. etc. or you submerge it in a graduated cylinder and measure the displacement ie. the water ...
