Ariver flows due south at 5 mi/h. a swimmer attempting to cross the river heads due east swimming at 3 mi/h relative to the water. find the true velocity of the swimmer as a vector. (assume that the i vector points east, and the j vector points north.)

Apebble is thrown into a calm lake, ripples are formed from the center and move outward. the water particles in the lake travel in a circular pattern that moves up and down on the surface of a lake, and the energy travels a) diagonally. b) downward. c) horizontally. d) upward.

In science and physics what is the standard unit of measure for speed?

Madison lives near the ocean. she’s formed a hypothesis that increased concentrations of salt in the air speeds the corrosion of certain metals. if madison plans to test this hypothesis, she will have to deal with the following variables in her experiment: dependent variable: independent variable: one possible confounding variable:
