Area around a charged object where the objects can exert a force on another charged objects is an electric

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving

The pressure proportional to the area a- inversely b- directly c- increase d-decrease

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy
