Which is being developed by chemists to supplement fossil fuels? solar cells lignite biodiesel nuclear power?

Fossil fuels are the most common form of non-renewable energy resources. Once used up, they cannot be replenished. More over, these fuels produce oxides of carbon, nitrogen and sulfur which cause the atmospheric pollution. So, there is a need for replacement of these energy sources by renewable and eco-friendly energy sources. Solar energy is a renewable source of energy. So, it would be a good alternative to fossil fuels. Similarly, bio-diesel is the biofuel extracted from plants. It is eco-friendly and is renewable.

So, the correct choices will be: solar cells and biodiesel.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
