nvm, i got it, questions used concepts we haven't learned, or are in later chapters, so i looked for it. useless book.

need help on all i need help with what happens when you disconnect the capacitor and connect to another. for the first question, i don't know how to manipulate the equations i know to make it solve, i always end up with capacitance and area and voltage as unknowns, i need one of those to...

some people in our lab created a cone with some of that posterboard stuff. its stronger than newspaper, but with enough layers, it should give the same results. now as a report back on mine, it worked.. during trials, but failed me when it was tested for a grade. :frown: that's 5 points...

think of static, and what it does concerning vehicle speeds around a curve

1. The electric field between the plates of a paper-separated (K(dielectric constant=3.75) capacitor is 9.21 x 10^4 V/m. The plates are 2.35 mm apart and the charge on each plate is .775 ìC. Determine the capacitance of this capacitor and he area of each plate. 2. A 6.5-microF capacitor is...

i have no problem with gay people. the only thing that annoys me is stuff like gay pride parades. i mean, so u like the same sex, ok, but u don't have to go out and make a huge deal out of it.

haha. while watching tv, there was a segment in some show (Max X?) that had the headless chicken. the people were able to keep it alive for weeks before they choked it while tryin to drop food down throat to feed it.

any suggestions on this lab? dropped from i guess 3 stories up and the vehicle must be around 50 grams. no parachutes or padding either.

could someone explain how rotation makes falling objects move slower?

is the solution M=R^3omega^2/2G or M=R^3omega^2/G or 2M=R^3omega^2/G what value for R do you use and please explain the how you get the omega because that is not covered in the book, and can you use another method not dealing with omega as well?

mattius uses the words "justified reasonably" my question is what is considered justified? saving human lives?

we got velocity first, around 1400, and then plugged into equation rv^2/T for mass. 6.67x10^-11 for G. one thing i thought was that you would use 180 million km for radius, not 360 million km due to the way the stars will rotate around each other.

for those people against animal testing, would they change their mind if, for instance, they have a disease, let's say... some type of cancer, and the doctor says you will likely die in 3 years. but, if in those 3 years, animal testing would present a cure for this cancer, is animal testing...

well.. since everything is soooooo far apart, they don't do much to each other.. i think? don't mind me, I am a newbie at physics.

suppose that a binary star system consists of two stars of equal mass. they are observed to be separated by 360 million km and to take 5.0 Earth years to orbit about a point midway between them. what is the mass of each? P. 135 "Physics: Principles With Applications" Fourth Edition. Giancoli...
