Two particles are separated by a distance of 15 cm. Particle A has a charge of +10 microcoulombs while Particle B has a charge of + 20 microcoulombs. Determine the magnitude of the force between the particles.

How many molecules are present in 3 mols of silicon dioxide (sio2)?

Anonzero net force acts on a particle and does work. which one of the following statements is true? the kinetic energy of the particle changes, but the speed of the particle does not change. the kinetic energy of the particle does not change, but the speed of the particle does change. the kinetic energy of the particle changes, but the velocity of the particle does not change. the kinetic energy and the speed of the particle change, but the velocity of the particle does not change. the kinetic energy, speed, and velocity of the particle change.

Using a caesar cypher with an offset of three characters (a -> d, b -> e, z -> c), what would be the correct cypher text for the plain text "attack at dawn"?
