As a way of determining the inductance of a coil used in a research project, a student first connects the coil to a 11.5 v battery and measures a current of 0.620 a. the student then connects the coil to a 24.0 v (rms), 60.0 hz generator and measures an rms current of 0.570 a. what is the inductance? l = mh

L = 100.24 mH

Explanation:

Given that

V= 11.5 V

I= 0.62 A

V(rms) = 24 V

f= 60 Hz

I(rms) = 0.57 A

resistance R

V= I R

11.5 = 0.62 R

R= 18.54 ohm

impedance Z given

V(rms) =  I(rms) Z

24 = 0.57 Z  ,Z= 42.10 ohm

inductor  impedance  

L= 0.10024 H

L = 100.24 mH

This is the inductance .

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.
