The correct answer to the question is : A) Long wavelengths and low frequencies.

EXPLANATION:

From Planck's quantum theory we know that the energy of any electromagnetic wave having certain frequency is E = $h\nu$ .

Here, $\nu$ is the frequency of the wave.

Hence, more is the frequency of the wave, the wave is more energetic.

We know that wavelength and frequency are inversely proportional to each other.

Hence, a low energy wave means a wave having long wavelength or low frequency.

Answer:

Explanation:

Until 2019, more than 3000 planetary systems have been discovered that contain more than 4000 exoplanets, since some of these systems contain multiple planets. Most known extrasolar planets are gas giants equal to or more massive than the planet Jupiter, with orbits very close to its star.

Answer:

$F'=2F$

Explanation:

The Coulomb's law states that the magnitude of the electrostatic force between two charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them:

$F=\frac{kq_1q_2}{d^2}$
