An object moving with a speed of 35 m/s has a kinetic energy of 1500 J. What is the mass of the object?

What happens when positive and negative charges are near each other?

Many new headphones on the market are called "noise reducing" because they take sound waves that come in from the outside and add a sound wave to it that is exactly opposite (out of phase) to it, these add together to make no noise.
