From the Electromagnetic Spectrum:

Radio, Micro wave, Infrared, Visible light, Ultra Violet, X rays, Y rays.

Only the Radio wave of wavelength 10³ m, has a positive power index, others have a negative exponent.

So these long waves form a smaller percentage.

Option A is correct. Others are not true.

GalinKa [24]

Answer:

The maximum potential energy of the system is 0.2 J

Explanation:

Hi there!

When the spring is stretched, it acquires potential energy. When released, the potential energy is converted into kinetic energy. If there is no friction nor any dissipative forces, all the potential energy will be converted into kinetic energy according to the energy conservation theorem.

The equation of elastic potential energy (EPE) is the following:

EPE = 1/2 · k · x²

Where:

k = spring constant.

x = stretching distance.

The elastic potential energy is maximum when the block has no kinetic energy, just before releasing it.

Then:

EPE = 1/2 · 40 N/m · (0.1 m)²

EPE = 0.2 J

The maximum potential energy of the system is 0.2 J
