Acrylic and PVC are both types of plastic, but they’re different compounds. Acrylic has the chemical formula C5O2H8 meaning it is made of 5 carbon atoms, 2 oxygen atoms, and 8 hydrogen atoms. PVC has the chemical formula C2H3Cl. Compare the masses of the atoms that make up these plastics and come up with an explanation as to why PVC is more dense than acrylic

You are the coordinator for a program that is going to take place at night in a rectangular amphitheater in the mountains. you will have no access to any electricity, but you must be able to illuminate the entire grounds. you know the intensity of the light from a lantern varies inversely as the square of the distance from the lantern. suppose the intensity is 90 when the distance is 5 m. a. write an equation to model the situation. b. solve for the constant of variation. c. write the equation to model the situation using the constant () of variation. d. you have been given lanterns with 40 light intensity. use your equation to solve for the distance from the lantern. e. you need to illuminate 225 km. how many meters do you need to light? f. how many lanterns will you need?
