Answer:
We conclude that star moving toward observer.
Explanation:
According to the theory of doppler effect of light.
There are two kind of shift 1 ) Blue shift 2 ) Red shift, in which
1 ) if source of light moving toward observer so the apparent frequency of light increase( wavelength decrease ). This is which we call blue shift
2 ) if the distance between source and observer is increase, so the apparent frequency of light decrease ( wavelength increase ). This is which we call red shift.
Here, in our case wavelength of H-star is decrease so we can say that star moving toward observer ( Blue shift ).
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
El factor mas importante para el exceso de peso es un exceso de energía creada por una alimentación excesiva
El peso de un cuerpo es definido por la relación entre la energía requerida para los procesos vitales del cuerpo, sus actividades físicas diarias y la energía suministra en forma de alimentos.
Cuando estos dos parámetros están en balance el peso es estable, pero cuando la cantidad de alimentos aumenta o el valor energético de los mismo aumenta se tiene un exceso de energía que el cuerpo almacena en forma de grasa corporal, este el el factor mas importante para el exceso de peso.
En conclusión el factor mas importante para el exceso de peso es un exceso de energía por una alimentación excesiva

because of gravitional pull
Answer:
Explained
Explanation:
This happens because the water cancels the focusing effect of our eye lens. A drop of water makes a lens because of the different refractive indices of water and air.
When we are underwater with naked eyes, the front part of our eye lens does not have different refractive indices anymore… both the inside lens and outside lens are essentially water ( lens inside our eyes are water only surrounded by a membrane)… hence, that part of the lens does not focus the light anymore. And thus, your eyes don’t work well anymore. (It can only partly correct for this, by bending the lens more)
When we put swimming goggles on, we remove the water and again have air in front of our eye lenses, and they work normally now. Obviously, we have created an extra interface between water and air in front of our swimming goggles. However, this surface(the goggle) is flat. And thus it does not function as a lens but only as a window.
