Which of the following processes does our Sun and other stars in our galaxy use to create energy?

Usimov [2.4K]

Answer:

fusion reaction

The simple answer is that the sun, like all stars, is able to create energy because it is essentially a massive fusion reaction. Scientists believe that this began when a huge cloud of gas and particles (i.e. a nebula) collapsed under the force of its own gravity – which is known as Nebula Theory.

What is the energy of light with a wavelength of 468 nm? (The speed of light

marshall27 [118]

The answer for the problem is explained below.

The option for the answer is "D".

Therefore the energy of the light is 4.25 × 10^-19 J

Explanation:

Given:

wavelength (λ) = 468 nm = 468×10^-9 m

speed of light (c) = 3.00 x 10^8m/s

Planck's constant is 6.626 x 10^-34J·s

To solve:

energy of light (E)

We know,

E =(h×c) ÷ λ

E = ( 6.626 x 10^-34 × 3.00 x 10^8) ÷ 468×10^-9

E = 4.25 × 10^-19 J

Therefore the energy of the light is 4.25 × 10^-19 J
