In the 1920s what did Edmund hubble notice about the galaxies
zlopas [31]
Hubble noticed that the galaxies were moving away from us, which meant the universe was expanding.

This is why constellations change over time. In some years, the Big Dipper won't actually look like a dipper anymore.

e-lub [12.9K]

Answer:

Explanation:

The case relates to interference in thin films , in which we study interference of light waves reflected by upper and lower surface of a medium or glass.

For constructive interference , the condition is

2μt = ( 2n+1)λ/2

μ is refractive index of glass , t is thickness , λ is wavelength of light.

putting the given values

2 x 1.53 x 350 x 10⁻⁹ = ( 2n+1) λ/2

λ = 2142nm /  ( 2n+1)

For n = 2

λ = 428 nm

This wave length will have constructive interference making this light brightest of all .

For n = 1

λ = 714  nm

So second largest  brightness will belong to 700 nm wavelength.

An electron with a speed of 0.965 c is emitted by a supernova, where c is the speed of light. What is the magnitude of the momen
Jlenok [28]

Answer:

1.0047\times 10^{-21}kg.m/s

Explanation:

Relativistic momentum is given by:

p=\gamma m u

where, \gamma=\frac{1}{\sqrt{1-\frac{u^2}{c^2}}}

Speed of the electron, u = 0.965 c (given)

Mass of the electron, m = 9.1 ×10⁻³¹ kg

\gamma=\frac{1}{\sqrt{1-\frac{(0.965c)^2}{c^2}}}=\frac{1}{\sqrt{0.2622}}=3.81

p=3.81\times 9.1\times 10^{-31}\times 0.965\times 3\times 10^8=1.0047\times 10^{-21}kg.m/s
