    What is the correct approach for solving thermodynamics questions?

    10^-3 comes because you have to take everything in si units for example in your final equation if you take r in joule mass should be in kg.

    Calculating Amplitude in Simple Harmonic Motion

    see the equilibrium point of smaller block is .05g/k = .01 m but initially it is at .03 m thus this excess distance is its amplitude . as after each oscillation it wll come back to this point .

    Calculating Electric Potential Energy of a Charge Configuration

    take all possible combinations of any two charges and find their potential energues using kQ1 Q2/r and add all the these/

    Definition of electric current

    see it is amount of charge passing through the given cross section in unit time . so if 10 C charge pases in i sec. then I= 10 A
