Three charges of equal magnitude of +q C are placed at the vertices of a right angled triangle ABC. Find the magnitude and direction of electric field at the midpoint P of the side AC

What is the approximate amplitude of this wave a.10 seconds b.15 centimeters c.30 centimeters d.15 seconds

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the

At what time will the interfering waves have an amplitudeof zero?
