1) what is the e lectric force between a glass ball that has +3.9 mC of charge and a rubber ball that has -5.0mC of charge and a rubber ball that has -5.0 mC of charge when they are separated by a distance of 3.5 cm? The Coulomb constant is 8.98755 x 10^9 N*m(sq)/C(sq). Answer in N.

2) Two electrons in an atom are separated by 1.5 x 10^ -10 m, the typical size of an atom. The Coulomb constant is 9 x 10^9 N*m(sq)/C(sq). What is the force between them? Answer in N.

3) Would you feel any electrical effects if you were inside the charged sphere of a van de Graaff generator? Why or why not?

New international studies have shown that the average yearly temperature in Canada could increase by over 10C in the next 100 years! No more winters, lots of extra rainfall due to the weather pattern changes. But mostly NO MORE WINTER!! I, for one, can't wait!

I have a black very heavy rock that has metal like qualities. It has a number of small wholes and is smoothed like it was worn by some process or another. It is also slightly magnetic.

if dinosaurs really roamed the earth, then why is there nothing said about them in the bible, or in the genesis, in the beginning? would the scientists be right if they say that the whole galaxy is not created nor made by a heavenly being? why or why not?

What is the total acceleration in m/s^2 of a bug on the rim of a 8.0 in. diameter disk if the disk moves from rest to an angular speed of 76 revolutions per minute in 5.0 s? And what is the degree(relative to the tangential acceleration)?

I found all of this information out about the problem:
tangential acceleration=.162
tangential velocity=.81192
tangential acceleration=.162
centripetal acceleration=.259

Thanks for helping!!!

When opening ice cream for the first time, it is always so easy to scoop. But once returned to the freezer and then used a second time (such as a day later) it is always so much harder. Why is that? There must be some logical explanation. We even did an experiment where we bought ice cream, stored it in the freezer for a day, opened it for the first time and it was soft. However, upon second use (a day later) it was hard...puzzling. Come on scientists; help us out on this one!

In order to convince any intelligent, worldly people that the moon landings were a hoax, please provide us with an intelligent answer to the following, or go and find someone who can, for instance a systems engineer or integrator.

Yes it is possible to shoot the moon landings in the desert, more so in the last 10 years, but perhaps not so convincingly in the 1960s. However, please describe the processes by which you would integrate the film production into the systems at Houston control, so that the 150 or so controllers there are fooled for the seven years of the Apollo program.

Did you not know that in the 1960s, you could not do “real time” systems integration of any kind. To put a system into the monitors of Houston control such that for 7 years the controllers were unwittingly seeing a simulation of moon shots rather than the real thing, you would need to bring down all the systems for some time, and you would have to do it repeatedly until you got the scam correct.
