Class of students investigate the power output of each student in the class. The class must decide whether they use a method using steps or a method using weights. The whole class must use the same method.
Plan what measurements the students should take and how these can be used to calculate and compare the power output of each student.
You may draw a diagram to help with your plan.

Asmall 21 kilogram canoe is floating downriver at a speed of 1 m/s. what is the canoe's kinetic energy?

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
