In an oscillating lccircuit, l= 1.44 mh andc= 4.52 μf. the maximum charge on the capacitor is 4.40 μc. find the maximum current.

0.054 A

Explanation:

We have given inductance

Capacitance

Charge

The energy stored in the LC circuit is given by

So energy

This energy is also equal to

So

i=0.054 A

So maximum current will be 0.054 A

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.
