<u>Answer:</u> The radiation emitted will have negligible mass number.
<u>Explanation:</u>
Radioactive decay is defined as the process in which an unstable nuclei breaks down into stable nuclei via various methods.
An isotope undergoes a radioactive decay to attain stability.
There are three types of decay process, but the process in which the emitted radiation carries a charge of -1 is beta decay.
Beta decay is defined as the decay process in which a neutron gets converted to a proton and an electron. In this decay process, beta particle is emitted. The emitted particle carries a charge of -1 units and has a mass of 0 units. The released beta particle is also known as electron.
Hence, the radiation emitted will have negligible mass number.
Here in the above situation when boy pushes the girl there will be equal and opposite force on boy as per Newton's III law.
Due to this action reaction law boy will also go back with some speed.
Since there is no external force on this girl + boy system so we can use momentum conservation principle here.
As per momentum conservation
So boy will go back with speed 0.2 m/s
Part b)
Since the boy and girl will always exert same force on each other by Newton's III law so it has no it matter whether the boy pushed the girl, the girl pushed the boy, or they put their hands together and pushed each other away.
As in all above cases the as per Newton's III law the force on them is always equal and opposite.
