A firetruck passes you on the way to a big conflagration on a balmy -12oC day.  If the siren is 256 Hz and the firetruck is traveling at 25 m/s what is the frequency you hear as the firetruck approaches and departs?

What is the electric flux when a uniform electric field of 9000 N/C passes through a flat square area of 2m2 at a 300 angle?

 A charge of 3µC is used to test the electric field of a central charge of 6C that causes a force of 800N. What is the magnitude of the electric field?

How far apart must two electrons be if the force between them is 1x 10-12N?

A charge of 2 µC is 0.5m from a charge of 3µC. Find the electric force.

if in the graph of displacement vs time's written that final position is 0 displacement. And in the velocity vs time graph, it's written that final velocity is minus. while we know that velocity is displacement's divided by time, when displacement is 0 velocity should be 0 too, EXPLAIN WHY VELOCITY IS MINUS INSTEAD OF 0

If mama drives a car in a circle path, from point A and come back to the point A. With path's long is 1000 m and velocity is 100m/s, time's taken is 10 s. Hence, Determine the displacement vs time's graph
