Moria is drawing the electric field lines around a pair of charges. one charge is positive, and the other charge is negative.
how should she draw the field lines?
a) away from each charge and meeting in the middle
b) away from each charge and curving away from one another
c) away from the positive charge and toward the negative charge
d) away from the negative charge and toward the positive charge

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem

With the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 1.90
