Ok so right now i know that half life is 5730 years...and I am trying to figure out the 1/16 the saber tooth lived compared to the recent new one...So i think this is basically a math problem but i have no idea where to start...please help me out..i really want to learn but after reviewing what...
Homework Statement
A carbon sample taken from the bone of a saber tooth tiger emits 1 beta emission a minute. A carbon sample of the same size taken from a frest piece of bone emits 16 beta emissions a minute. How long ago did the saber tooth tiger live? How can i do this?

This is what i found...
The electrical potential energy of a charged particle is increased when work is done to push it against the electric field of something else that is charged. Just as work is done to compress a spring work is done in pushing the charge against the electric field of the...
Honestly nothing...but this is kinda like earth..earth is so large that it consumes an infinite amount of energy and it never over flows..etc...so I am thinking...would it require more energy to add a electron to a small generator because its more compact?...i really don't want to go off topic...
Van de Graaff generator? adding a electron??
Homework Statement
A)If a Van de Graaff generator is charged to 5,000 volts, how much energy does it take to add and additional electron to the charge on the sphere? If the charge of an electron is -1.6 x 10 ^-19...
B) How would the voltage...
Cool so if i did my calculations right...i got 2.3 x 10^-28 N am i close or am i really off? but i think this force is repulsive no? because its a positive number ...or is it attractive?
Well let me put what i have... F=9 x 10^9 N x m^2/c^2 X( 2.6 x 10^-38 c^2 /1 m^2)
that is what i have...do i cancel out the m^2 and c^2? from both sides? so that only the N is remaining?
Thats the thing i don't know...do you add the exponents together??
2.56 x 10^-38?
1.6 x 1.6 = 2.56 but what about the 10^-19? do i add them or does it stay the same?
Actually now i got 2.6 x 10 ^-38...by multiplying both
Question with large number?electron charge?
Homework Statement
The electric charge of an electron is -1.6 x 10^-19 C. What is the force exerted between two electrons separated by one meter? Is it attractive or repulsive?
