Choose the statement about masters sports programs that is true. a. masters programs allow adults to both exercise and socialize with people who share their love of a sport. b. masters programs are only for people who competed in high school or college sports. c. all masters programs require members to compete. d. you have to be over 30 to join most masters teams.

Option A

Explanation:

Master sports programs are an initiative that allows Adults to join their favorite sports.Masters programs allow adults to both exercise and socialize with people who share their love of a sport. It helps the Adults to build a camaraderie and enjoy the sports they love the most. This way they can sustain the passion for the sports.

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.

less than one you can't create energy
