Electrical Force And Its Characteristics
The repulsive and attractive interaction between two charged particles is an electrical force. The electric force between two electrons is equal to the electric force between two protons when placed at equal distances. Some examples of electric force are as mentioned below: 1. Charge in a bulb. 2. Static friction between cloth when rubbed by a ...

A jet plane at take-off can produce sound of intensity 10.0 W / m^2 at 30.0 m away. But you prefer the tranguil sound of normal conversation, which is 1.0μW / m^2 . Assume that the plane behaves like a point source of sound. (a) What is the closest distance you should live from the airport runway to preserve your peace of mind? (b) What intensity from the jet does your friend experience if she lives twice as far from the runway as you do? (c) What power of sound does the jet produce at take-off?
