Explanation: why because 37/19 k toward 0+1e +37/18 AR is equivalent to the beta decay and it describes the best beta decay in the formula.
In the periodic table, there are seven horizontal rows of elements called periods.
Answer :
and
Explanation:
According to Boyle's law, it states that pressure is directly proportional to the volume of the gas for a fixed amount of gas and at constant temperature.
The equation given by this law is:

where,
are initial pressure and volume.
are final pressure and volume.
Thus the correct relation for pressure and volume for a fixed amount of gas at constant temperature according to Boyle’s law is
and
