What is the standard unit force is measured in?
O Newton
O Kg. m/s
O Tesla
O Grams

Force is measured in "Newton's" - kg-m/s^2

F = M a = kg * m/s^2

This in the kgm-m systen - in the gram-cm system you have

F = dynes = gram-cm/s^2

Since 1 gm = .001 kg and 1 cm = .01 m

1 dyne = 1.0^-5 newtons

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.

heat is transmitted by radiation
