IM IN A TEST help needed Generators are used to convert chemical energy into electrical energy. One company
that designs generators claims that their newest design can convert 1,000 joules of
chemical energy into 1,200 joules of electrical energy. What conclusion can you draw
about this company's design?

A No conclusion can be drawn without more information,
B It has a very good and realistic efficiency.
C It is impossible to convert chemical energy into electrical energy.
D It is impossible to create more energy than was input.

Eddy whose mass is 55kg climbs up the 1.50 meter high stairs in 2s. calculate eddy’s power rating

Aperson standing in a canoe exerts a force of 700 n to throw an anchor over the side. find the acceleration of the canoe if the total mass of the canoe and the person is 100 kg?

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to. in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?
