Ans. 4. Higher electric potential.\n\nA positive charge will go from a region of higher to lower electric potential.\n\nA negative charge will go from a region of lower to higher electric potential. Since electron is a negative charge, it should go to a higher electric potential.

If you say that C is correct and I agree, this is because in the diagram you see that U is the positive end of the battery,  and thus at a higher potential. V is the negative end and thus less(zero). At W, the potential is same as V because there is no resistance(negligible) in the wire. \nAs R is directly proportional to resistance potential, thus X is at a higher potential. Then, Y is same as X, and Z is higher than Y because of the same reason.

It's two.  Energy goes as the square of amplitude.

balanced is the best answer, although constant would be correct as well....or if you're looking for a numerical answer, it would be 0

When they're both at the defined zero of potential energy (usually "the ground" in a physics problem).  Both would have a potential energy of zero.

Assuming it can't be II and III, I would say it's all of the above. The potential energy is converted into kinetic - the velocity increases and the height decreases. The KE + PE remains constant, because there is no work being done because there is no force here (besides gravity). However, the first depends on how you define mechanical energy - if it's kinetic energy, it's true. If not, I really don't know what it is.

When an electron goes from lower energy orbital to higher energy orbital it absorbs energy and when an electron drops from a higher energy orbital to a lower energy orbitaltehn it emits energy.\n\n(a) Emission (read the reason above)\n(b) Absorption (Read reason above)\n(c) Emission (read reason above)\n(d) Absorption (read reason above)

There is potential energy and kinetic energy.  Kinetic energy is the energy that something has from motion.  It's equation is E=1/2*m*v(squared) where m=mass and v=velocity.  For potential energy there are many forms.  Gravity E=mass*height*gravity, Electric and magnetic fields are potential energy.  And nuclear energy E=m*c(squared) which is the rest potential energy that anything with mass will have.  There is also energy from light E=h*nu, nu=frequency h=planck's constant.  There is also chemical potential energy which is the energy contained within molecules.

The correct answer is C, standard potential should be positive.\nIf you can't remember the correct sign easily, think that the general rule is that for spontaneous reactions of any type ΔG<0 and since for redox reactions ΔG= -nFE, E has to be positive.
