Human populations all over the world burn fossil fuels to power cars, planes, and generate electricity. select the statement that best describes the long–term global effects of this behavior. a.) burning fossil fuels pollutes the environment and our heavy reliance on them creates a long–term problem because they are not a renewable resource. b.)countries will not need to spend money on investigating other sources of energy because fossil fuels are abundant. c.) fossil fuels burn clean so the pollution problem is not really a source of concern for the future. d.) as populations increase, the need for fossil fuels will decrease; therefore, there will always be an abundance.

The illuminance of a surface varies inversely with the square of its distance from the light source. if the illuminance of a surface is 120 lumens per square meter when its distance from a certain light source is 6 meters, by how many meters should the distance of the surface from the source be increased to reduce its illuminance to 30 lumens per square meter?
