Because they are so far away that the distance has to be measured in light years. Each light year is around 10 trillion kilometers, which is a very large distance.
Answer:
You will feel more weight if it is accelerating out of the planet.
You will feel less weight if it is accelerating towards the planet.
Explanation:
The weight that you are observing or feeling is basically due to the change in acceleration of your fall or rising up in the spaceship. When the acceleration is stationary on the surface, you experience your normal weight due to the gravitational acceleration of that planet.
When the spaceship accelerates above or out of the planet you experience acceleration more than the acceleration of gravity hence more weight.
When the spaceship accelerates towards the planet you experience acceleration less than the acceleration of gravity hence less weight.
If the spaceship is free falling at the gravitational acceleration you experience a zero weight
Answer:
do you mean before we used fossil fuels? steam.before steam? fire was used for like ...125,000 years ago. we were not smart back then but we were smart enough.
Explanation:
Answer:
Therefore the correct statement is B.
Explanation:
In the interference and diffraction phenomena, the natural wave of electromagnetic radiation must be taken into account, the wave front that advances towards the slit can be considered as when it reaches it behaves like a series of wave emitters, each slightly out of phase from the previous one, following the Huygens principle that states that each point is compiled as a source of secondary waves.
The sum of all these waves results in the diffraction curve of the slit that has the shape
I = Io sin² θ /θ²
Where the angle is a function of the wavelength and the width of the slit.
From the above, the interference phenomenon can be treated as the sum of two diffraction phenomena displaced a distance equal to the separation of the slits (d)
Therefore the correct statement is B
We know but What’s ur question?!!!
