Which of the following laws relates emf, potential, current, and resistance in a circuit? ohm’s law newton’s law of gravity coulomb’s law conservation of charge

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.

What is the quantity which is measured by the area occupied below the velocity- time graph?
