When two or more capacitors are connected in series across a potential difference:
a) the potential difference across the combination is the algebraic sum of the potential differences across the individual capacitors.
b) the equivalent capacitance of the combination is less than the capacitance of any of the capacitors.
c) each capacitor carries the same amount of charge.
d) all of the above choices are correct.
e) none of the above choices are correct.

Where do magnetic lines of force enter earth?

The items in the following list are all units of matter. which is the smallest unit that retains the properties of the matter? a.) atom b.) compound c.) electron d.) element

An electron is ejected into a horizontal uniform e⃗ field at a parallel horizontal velocity of v0. assume the electron's initial position x0, initial velocity v0, time t, magnitude of electric field e, electron's mass m, and the magnitude of the electron's charge |e|. ignore the force that earth exerts on the electron. assume the e⃗ field is in the same direction as the initial velocity. part a define the equation for the electron's velocity. express your answer in terms of the variables v0, |e|, t, e, and m.
