How much work is done by moving a 20kg object 20m using a force of 100 newtons parallel to the direction of motion?

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

State the following: boyle's law and charle's law

Which statement best describes the superposition principle? a.) if two in-phase waves arrive simultaneously at a point, their amplitudes add up b.) if two out-of-phase waves arrive simultaneously at a point, their amplitudes add up c.) if two in-phase waves arrive at a point one after another, their amplitudes add up d.) if two out-of-phase waves arrive at a point one after another, their amplitudes adds up
