An l-c circuit has an inductance of 0.450 h and a capacitance of 0.200 nf . during the current oscillations, the maximum current in the inductor is 1.40

a. part a what is the maximum energy e max stored in the capacitor at any time during the current oscillations?

0.441 J

Explanation:

The maximum energy stored in the capacitor = maximum energy stored in inductor, E = 1/2Li². where L = inductance = 0.450 H and i = current = 1.40 A

E = 1/2Li² = 1/2 × 0.45 × 1.40² = 0.441 J

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.
