a reconnaissance plane flies 428km away from its base at 876m/s, then flies back to its base at 1314m/s. What is the average speed?

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.

its c its is a mixture of gases

3. dark matter

empty space could also be a simple vacuum

did yall get answers for this yet
