In a rural region of India, scientists collected data of different pesticide residue levels from closely located farming plots.
Some of these plots used integrated pest management biopesticides, while others used chemical pesticides to control pests. The data below show levels of four pesticide residues found in tomato and cucumber crops in the two treatment plots. Help
The standard unit used to measure energy and work done in physics is the joule, which has the symbol J. In mechanics, 1 joule is the energy transferred when a force of 1 Newton is applied to an object and moves it through a distance of 1 meter. Another unit of energy you may have come across is the Calorie.
