Add 1965g and 62.2kg and express your answer in milligrams(mg)

Answer is 64165000mg

Explanation:

solution

change all units to one category were gonna start with Kg to g

1kg=1000g

62.2kg=?

62.2 × 1000g

1kg

=62200g

+1965g

64165g

=64165g

(then we change from grams to milligrams)

1g=1000mg

64165g=??

64165 × 1000mg

1g

=64165000mg

(Hope I was helpful,sorry and thank you)

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.

the bal will not change its velocity.
