How does the arm wrestling tournament represet what rutherford found out about the positive and negative charges and atom

In the arm wrestling tournament each opponent is trying to pin down the arm of the other.  Similarly, in an atom if there were only electrons or only protons they would each repeal the other very strongly. This is because like charges repeal each other.

But if there are both equally strong arm wrestlers then one will not be able to defeat the other. In the same way atoms have equal number of protons and electrons which strongly attract each other. Thus stabilizing the atom.

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
