Answer:
Explanation:
We have given the radius of first sphere is 10 cm and radius of second sphere is 20 cm
So the potential of first sphere will be greater than the potential of the second sphere, so charge will flow from first sphere to second sphere
Let q charge is flow from first sphere to second sphere and then potential become same
So 
200-100=2q+q
So 
We know that potential energy U=qV
Carbon-13 has an atomic mass of 13.
Atomic mass is the sum of protons and neutrons.
There are 6 protons, so there are 13 - 6 = 7 neutrons.
Answer is 7 neutrons (and 6 electrons)
Answer:
hey dream I m your big fan for u I have answered this question The third one is correct.
The maximum is 1800 J since energy is not created nor destroyed, it is just transformed. In this example, gravitational potential energy is transformed to kinetic energy.
DEFINITELY C
c is the most accurate answer the others dont make sence
