Which of the following choices describes the type of image formed by a plane mirror?

Virtual, Upright and the same size

Explanation:

As we know for plane mirror we have

image distance is same as that of object distance but on opposite side of the mirror.

now for the magnification we have

since magnification is positive so it must be virtual and upright image and since the magnitude of magnification is exactly 1 so it must be of same size as that of object size

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

muscle endurance

explanation:

i can do 50 in a row ( but i get so tired after that)
