Answer:
Neptune
Explanation:
The solar system is made up of the sun with its associated planets, asteroids, meteors, satellites (i.e.,moons), and comets orbits around it. The Sun is a yellow dwarf star. Its gravity holds the solar system together, keeping everything in its orbit.
Although Neptune travels at a very high speed of 5.43 km/s, Neptune still has the slowest orbital velocity of any of the planets.
The wavelength of the light that are not reflected in the air is,
λ5= 600 nm, λ6= 500 nm, λ7=428 nm.
<u>Explanation:</u>
- For the above problem, we have the case as no<n1 and n2 < n1 .
- so we have(1<1.5;1.4<1.5)To find the wavelengths of the light that is not reflected in the air.
- Since the phase changes are not common on both the surfaces/
- we have the formula, λ=2d n²/m ( where m=1,2,3,4,5...)
- solving the problem we get,
- λ5= 600 nm, λ6= 500 nm, λ7=428 nm
- The wavelength of the light that are not reflected in the air is,
λ5= 600 nm, λ6= 500 nm, λ7=428 nm.
The people in the ship will see light travelling toward them at speed of light.
<u>Explanation:</u>
As the spaceship is moving away from the space station with one half speed of light. The light travelling from the space station with velocity c which is also termed as speed of light will be moving relative to the people in spaceship. So the relative velocities can be found as
In this case, u’ is the speed of light seen by the people in spaceship and u is the velocity of light while v is the velocity of moving spaceship.So u =c and v = . Then
Thus, the light travelling towards the people in the ship will view that light with the speed of light itself.
Answer:
4.35x10¹⁷s is the age of the universe
Explanation:
The age of the universe is 13.8 billion years.
As we know, 1 billion years = 1x10⁹years
13.8 billion years * (1x10⁹years/ 1 billion years) = 13.8x10⁹ years.
As 1 year = 3.154x10⁷ seconds, 13.8x10⁹ years are:
13.8x10⁹ years * (3.154x10⁷ seconds / 1 year) =
<h3>4.35x10¹⁷s is the age of the universe</h3>
