Which of the following is a set of vectors?mass, weight and densityacceleration, moment and velocityforce, mass and momentmass, volume and density2. Imagine that we have access to a machine that collects energy over a period of time, and then converts all the energy into matter. We employ that machine to collect sunlight for a few weeks, and then push a button marked "Make Matter!"How can we calculate the mass of the resulting material sample in kilograms?divide the square of the speed of light in meters per second by the total collected energy in jouleswe can'tdivide the total collected energy in joules by the square of the speed of light in meters per secondmultiply the total collected energy in joules by the square of the speed of light in meters per seconddivide speed of light in meters per second by the total collected energy in joules3.
