P1 1) Give 5 ways energy can be stored? Chemical energy, kinetic energy, gravitational potential energy, elastic potential energy and thermal energy, P1 2) What is chemical energy stores? Energy transferred during chemical reactions. Stores include fuels, foods or chemicals found in batteries. P1 3) What is kinetic energy stores? Energy stored in an object because it is moving P1 4) What is gravitational potential energy? Energy stored in an object because of its positio...

What is natural movement in a gravitational field? - correct answerAll objects move in the direction of the g field on their own. Unnatural movement is against the field (when a force is exerted against the field). What is Displacement? - correct answerDisplacement is the change in location of an object. What is Velocity? - correct answerVelocity is the rate of change of displacement (x) v=x/t What is Acceleration? - correct answerAcceleration is the rate of change of velocity (v) a=v/t...

In Dr. Terry Tollefson's videos on soil biology, he presented several microscopic organisms that were found in the soil sample. Other than bacteria, identify three other microscopic organisms from the video using one well-written sentence. - Dr. Terry Tollefson's video identified protozoa, nematodes, and mites. During lecture, Dr. Burton presented soil test results from two of his farm fields. What contributed to the "excessive" level of phosphorus in one of the fields? - The previous o...
