Experiments need to be repeated by the scientist and also replicated by other scientists. true
false

false

Explanation:  because the other scientists could've missed something in there experiment

b. latent learning (the word "latent" itself means something that exists but isn't obvious, only under certain conditions! )

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.
