The sun produces large amounts of energy. By what process does the sun produce energy?

1 answer:

8 0

The sun produces energy by converting gravitational potential energy into radiation via quantum processes in the nucleus of the atoms.

Since the mass of the sun and it's temperature are not quite enough to generate nuclear FUSION on their own, quantum tunneling is the primary process by which nuclear fusion occurs in our sun, SOL. FISSION also occurs as a result of this fusion.

Additionally, gravitational potential energy is also the reason that supernovae are so bright. Cool!

Electrons are ejected from sodium metal by any light that has a wavelength shorter than 544 nm. What is the kinetic energy of an

wel

Answer:

KE=2.3 x 10⁻¹⁹ J

Explanation:

Given that

λ = 544 nm

λ' = 485 nm

The kinetic energy KE given as

KE= E - Ф

Where

$E=\dfrac{hC}{\lambda'}$

$\phi=\dfrac{hC}{\lambda}$

h= 6.626 x 10⁻³⁴

C=3 x 10⁸ m/s

Now by putting the values

$KE=\dfrac{hC}{\lambda'}-\dfrac{hC}{\lambda}$

$KE=\dfrac{34.34\times 10^{-34}\times 3\times 10^8}{485\times 10^{-9}}- \dfrac{34.34\times 10^{-34}\times 3\times 10^8}{544\times 10^{-9}}$

KE=2.3 x 10⁻¹⁹ J

This is kinetic energy.

Which are responsible for holding atoms together?

Scrat [10]

Hey there!

Your answer: shared electrons

There would usually be two forces that would make an atom stick together. It would be the positive, and negative of a electric charge. All this coming together would be the electromagnetic force. This is liked we talked about, both positive and negative charges attracted. And that would be the strong force. Which then gives our answer to be electrons.
