Imagine that a 500 kg box is at rest on a surface. Assume that the surface has no friction that would slow the box down. A person applies a 250 N net force in an eastward direction to push the box. What will be the acceleration?

Aspectroscope breaks light up into its colors, allowing scientists to analyze light from the solar system and universe. by studying the spectral line patterns, widths, strengths and positions, scientists can determine the speed, position, and of celestial bodies. a) age b) origin c) rotation d) temperature
