Jim is rearranging his apartment and needs to move his entertainment center. if the gravity exerts 15 n and there is 10 n of friction, how much force will jim need to exert to move it?

Which quantities are scalars? choose all that apply a. distance b. speed c. acceleration d. velocity

When considering gravity acceleration and the force of acceleration, what must be true? a. the direction of acceleration must be perpendicular to the direction of the force. b. the direction of the force and the direction of acceleration must be the same as each other. c. the direction of the force and the direction of acceleration must be opposite of each other. d. the mass of the body must be the same as the acceleration of the body.

The experiment was repeated many years later but the gases were mixed in a different type of container. a white solid was obtained which was xenon fluoride. predict whether you think 1) krypton and 2) radon will react with fluorine. explain reasons for your predictions
