Gravity is a force between any two objects with mass why doesn’t a person feel a fractional force between him/herself and another person ?

Best way i know to answer it is you do! However its not alot of mass to acually feel the force,

Explanation: Lets say you weigh 150 pounds here on earth. Then you go to the moon somehow, you'd weigh 22 pounds on the moon!  There for you standing near whoever, then theres around a 0.000000000012 force pulling on you, and you don't feel it because its such a small force being pulled.

If this answer helped please mark it as right <3 ty hope this helped!

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases . this process does not change the mass number.

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as -decay. in this the mass number remains same.

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.
