Suppose there was a release of 1 mole of Alpha emission particle and 1 mole of Beta emission particles and both particles are accelerated to 20.50 MeV. What is the total energy in kJ/nuclei?

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
