For a fixed height h2 if you plot v2kin versus d, what kind of curve would you get? a straight line with a positive slope of g 2h2 there is not sufficient information to answer this question a straight line with a negative slope of g 2h2 a horizontal line parallel to the x-axis a parabola

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.

their crystal patterns have been disrupted by stress
