the molar mass of oxygen is 32g and the spring constant of the bond is 28N/m what is the smallest amount of vibrational energy of an oxygen molecule?​

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.

small = small current large mag large current

it doesn't. it was imagined up in the middle ages.

friction

explanation:

they us to move forward and backwards
