How can I solve this? What is the electric potential (in units of Volts) at the position of the red dot, which is 0.2 m from each of these charges? What is the value of the electric field (in units of N/C) at the position of the red dot, which is 0.2 m from each of these charges? Enter your answer as a whole number only in the box below. Use k = 9 x 10^9 Nm^2/C^2 in your calculation and remember 1 nC = 1 x 10^-9 C.

7types of electromagnetic waves from lowest to highest frequency

Atrain is traveling at 30.0 m/s relative to the ground in still air. the frequency of the note emitted by the train whistle is 262 hz. the speed of sound in air should be taken as 344 m/s. what frequency (f approach) is heard by a passenger on a train moving at a speed of 18.0 m/s relative to the ground in a direction opposite to the first train and approaching it? what frequency (f recede) is heard by a passenger on a train moving at a speed of 18.0 m/s relative to the ground in a direction opposite to the first train and receding from it?
