Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.

Calculate the volume of this regular solid. what is the volume of the cone? round your answer to the nearest hundredth
