The best answer is D) Inertia
Inertia is the word assigned to the Newtonian law of motion that an object in motion tends to stay in motion, in a straight line and in the same direction at the same speed, as long as no other forces are acting on it.
In deep space, there is no air resistance or any other force that would change the ship's velocity, so the law of inertia would keep it moving at the same speed forever.
No one is entirely sure of where the universe came from. Scientists have come up with several different theories relating to your question, including the Big Bang Theory, but there is no definite answer.
Answer:
the reflected wavelength is lano = 4.55 10⁻⁷ m which corresponds to the blue color
Explanation:
This is a case of reflection interference, we must be careful
* There is a 180º phase change when light passes from the air to the soap film (n = 1,339), but there is no phase change when passing from the pomp to the plastic (n = 1.3)
* the wavelength within the film is modulated by the refractive index
λₙ = λ₀ / n
if we consider these relationships the condition for constructive interference is
2 t = (m + ½) λₙ
2t = (m + ½) λ₀ / n
λ₀ = 2t n / (m + ½)
we substitute the values
λ₀= 2 255 10⁻⁹ 1,339 / (m + ½)
λ₀ = 6.829 10⁻⁷ (m + ½)
let's calculate the wavelength for various interference orders
m = 0
λ₀ = 6.829 10⁻⁷/ ( 0 + ½ )
λ₀ = 13.6 10⁻⁷
it is not visible
m = 1
λ₀ = 6,829 10⁻⁷/ (1 + ½)
λ₀ = 4.55 10⁻⁷
color blue
m = 2
λ₀ = 6.829 10⁻⁷ / (2 + ½)
λ₀ = 2,7 10⁻⁷
it is not visible
therefore the reflected wavelength is lano = 4.55 10⁻⁷ m which corresponds to the blue color
Answer:
the distance between the submarine and the ocean floor is 11,250 m
Explanation:
Given;
speed of the wave, v = 1500 m/s
time of motion of the wave, t = 15 s
The time taken to receive the echo is calculated as;
Therefore, the distance between the submarine and the ocean floor is 11,250 m
Electromagnetic waves going through outer space has the greatest speed among all kind of waves.
Option B
<u>Explanation</u>:
Electromagnetic waves are the waves that can go through the vaccum of space. Electromagnetic waves are made by the vibration of an electric charge. This vibration makes a wave that has both an "electric and magnetic nature". An electromagnetic wave transfers energy through a vaccum at a speed of 
(speed esteem ordinarily depicted by the sign c). The spread of an electromagnetic wave through a material medium happens at a net speed which is under .
