a horse moves a sleigh 1.00 kilometers by applying a horizontal 2000 Newton force on its harness for 45 minutes. what is the power of the horse?

Answers

-- If 2,000 newtons of force were applied through a distance of 1,000 meters,
then 2,000,000 newton-meters = 2,000,000 joules of work were done.

-- 45 minutes = (45 x 60) = 2,700 seconds

-- Power = (work) / (time) = (2,000,000 j) / (2,700 s) = 740.74 watts

Interestingly, that's almost exactly 1 horsepower. (0.99295... of 746 watts)

Why do different elements emit different colors of light

Answers

Answer:

different photonic energies

Final answer:

Elements emit different colors of light based on their electron configurations and the amount of energy released.

Explanation:

Each element has a unique arrangement of electrons in its atoms. When these electrons transition from higher energy levels to lower energy levels, they release energy in the form of light. The color of light emitted depends on the amount of energy released.

For example, sodium emits yellow light because its electrons transition from a higher energy level to a lower energy level, releasing a specific amount of energy corresponding to the yellow part of the visible spectrum.

Other elements, like copper or lithium, emit different colors of light because they have different electron configurations and release energy at different wavelengths.
