Answer:

225 J

Explanation:

Work = change in energy

W = 1/2 mv²

W = 1/2 (0.020 kg) (150 m/s)²

W = 225 J

A pendulum has 141 J of potential energy at the highest point of its swing. How much kinetic energy will it have at the bottom o
Lubov Fominskaja [6]
Assume that energy losses (due to aerodynamic resistance or bearing friction are negligible).

At the highest point, the pendulum has its maximum potential energy (PE) and zero kinetic energy (KE). The total energy is equal to the PE = 141 J.

At the lowest point, the pendulum has its maximum KE, and zero PE. The total energy is equal to the KE.

Because energy is preserved, therefore
KE at the lowest point  = PE at the highest point  = 141 J.

Answer:  141 J

Which part of the electromagnetic spectrum is divided into seven ranges of wavelengths and is the part visible to the human eye
oksano4ka [1.4K]
In one of the most amazing coincidences in all of science,
the part of the electromagnetic spectrum that's visible to the
human eye is called "visible light".

Visible light is not 'divided' into anything. We mention the names
to seven of the colors in visible light. But all of the thousands of
OTHER colors that we can see are in there too, even though we
don't bother to list their names when we buzz through the rainbow
in the third grade.
