How is speed calculated? A)multiply velocity by displacement B)divide velocity by displacement C)multiply distance by time D)divide distance by time

What is special about a dc circuit ?

Use the illustration to describe how the electromagnetic spectrum changes as its frequency moves from radio waves to higher energy gamma waves in terms of wavelength and amplitude.

The average time that it takes for the car to travel the first 0.25m is s. the average time to travel just between 0.25 m and 0.50 m is s. given the time taken to travel the second 0.25 m section, the velocity would be m/s.
