Tennis

Explanation:

Much more than balls here and there. Tennis, one of the most traditional and practiced sports in the world, is also synonymous with technique, tactics and, of course, body benefits. So much so that, according to the most diverse studies done by sports science, the sport usually comes as one of the most complete physical activity for our health, being indicated to all people!

Tennis is considered an aerobic activity because it stimulates the function of the cardiorespiratory and vascular systems as well as metabolism, since it increases the cardiac and pulmonary capacity to supply muscle energy from oxygen consumption.

Tennis is also considered an anaerobic activity because it uses a form of energy that is not dependent on the use of oxygen, and is made with high intensity and short duration. It involves a more intense effort as it is performed by a limited number of muscles (there is also production of lactic acid).

Answer from: Quest

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.

$_a^z\textrm{x}\rightarrow _{a-2}^{z-4}+_2^4\alpha$

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.

$_a^z\textrm{x}+_{-1}^0\textrm{e}\rightarrow _{z-1}^a\textrm{y}$

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 $\gamma -radiations$ . this process does not change the mass number.

$_a^z\textrm{x}^*\rightarrow _a^z\textrm{x}+_0^0\gamma$

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 $\beta ^+$ -decay. in this the mass number remains same.

$_a^z\textrm{x}\rightarrow _{z-1}^a\textrm{y}+_{+1}^0e$

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