Describe infrared and ultraviolet light. discuss atleast 2 ways that they are alike and 2 ways they are different.

Both are electromagnetic radiation following specifically to the electromagnetic spectrum. However, infrared has a much longer wavelength, and has less energy, while ultraviolet has a much shorter wavelength, and has more energy.

Work is reduced while time is decreased

The answer is  the potential energy of the bob at position b is 1.47 joules.if the maximum height of the bob is 0.45 meters when it swings back,1.323   joules of energy was transformed to thermal energy.hope this
