Airplane a is flying north with a constant horizontal velocity of 488 km/h. airplane b is flying southwest at the same altitude with a velocity of 567 km/h. from the frame of reference of a, determine the magnitude vr of the apparent or relative velocity of b. also find the magnitude of the apparent velocity vn with which b appears to be moving sideways or normal to its centerline. would the results be different if the two airplanes were flying at different but constant altitudes?

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
