Two identical conducting spheres, fixed in place, attract each other with an electrostatic force of -0.5610 N when separated by 50 cm, center-to-center. The spheres are then connected by a thin conducting wire.
the wire is removed, the spheres repel each other with an electrostatic force of 0.0001 N.
were the initial charges on the spheres? Since one is negative and you cannot tell which is positive or negative, there are two solutions.
the absolute value of the charges. a) What is the smaller value? b) What is the larger value?

Neptune has a mass 17.2 times larger than that of Earth and a radius 3.88 times larger. A person weighing 128 lb on the Earth would weigh how much on Neptune? HELP: Begin with Weight=GmpMe/re2 and alter this to take into account Neptune's mass and radius. HELP: It's a simple ratio. Remember, it's asking for weight, not mass.
solving the problem could you please include a short explanation of how you got the answer and also round to 5 decimal places.
answer should be around 144lbs.
for the help.

I have heard on many occasions that in the quantam level particles can be at many different places at the same time.
is this possible beacuse according to classical mechanics and general reletivity that is absurd.
this have anything to do with the wave principle.

Okay so this is my senior year and I have a few questions, first of all I want to know what science classes I need to go to a UC or private University.
What I know you need 2 years of either Biology, Chemistry or Physics.
year I got this class which was" Ant/Phy" Is is a Physics class, this class was about the human body and all of that stuff.
this year im taking chemistry.
in freshman year I got this science class which was Intcoor Sci and then in sophomore year I got Intcoor Sci 2. Do these classes count for part of the 2 years of the requirements? Oh yeah and I also got a D in the the first semester of Intcoor Sci 2 do i need to make it up in community college?

All these girls always act nice to me and stuff cause im a pretty smart guy i have a 93% average and i really like all science classes especially chemistry, physics and i also really like math.
it always seems girls try to get me to ask them out so they can copy my answers and help them tutor them after school.
when i ask them to go with me somewere they always say no till i ask them if their using me and they usually say yes. I want to find a meaningful girlfriend but this has been going on since gr.9 and its now my last year of highschool gr.12. What should i do?

Im in 11th grade and heres my schedule (we run block) Spanish 3A Algebra 2A H Chemistry i really dont see a need in spanish 3A, i mean i took 2 years and i know 3 is recomended but i feel like if i take another class would be better, its just spanish and im sure that i would only need that if im gunna do business and i dont plan on it.
other class should i take instead of spanish 3A? also, i never took an AP class and im thinking of taking AP chemistry but i dont know if im up for it. I already took physics in 10th grade (i dont know why they put me in it) and i got a B.
