Review the results of your first experiment from task 2, part B. When force is fixed, does an increase in mass increase or decrease acceleration? The equation for Newton’s second law is . Do your results support Newton’s second law?

explanation: no but i do not usually comment

i do not get it   at all

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
