Atom are made of three basic components. name these three particles.

When you turn on a battery-operated device, an electrical circuit is

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.

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