How will our Sun die?

Our Sun is in the main sequence star stage.
From there our Sun will evolve to be a red giant.

When it evolves many many years from now it will engulf all of the inner planets. But don't worry, that won't happen in our lifetime!

From there the red giant (sun) will die. The death of a red giant is known as a planetary nebula. Though at the center of the nebula there is still a burning core.
When the debris flies away from the planetary nebula, our Sun will turn into a white dwarf, then the core will burn out which gives us a black dwarf.

I've provided an image of a good life cycle of the star, if you follow along with the brief description I've given you it should make sense!

If you have any questions let me know! I hope this helps!

The diagram shows a ray of light striking a mirror that is above a sink full of water explain what what will happen to the beam of light as it leaves the mirror and then enters the water

According to the law of reflection, the angle of incidence is the angle between the line normal (or perpendicular) to the surface and the light interacting with the surface of the water  . So the angle of the light to the mirror will be equal to that of the mirror reflecting light into the water.

Which statement is true about light when it slows down upon entering another medium? A. Light bends less, and there is greater refraction B. Light bends more, and there is greater refraction C. Light bends more, and there is less refraction D. Light bends less, and there is less refraction. HELP FAST PLEASE :( so stressed lol

Answer: B. Light bends more, and there is greater refraction.


Refraction is the bending of light when it moves from one medium into another. When light moves from a rarer medium to a denser medium from example from air to glass,  it travels slowly in glass and this leads to the bending of light towards the normal.

When light travels from a denser to a rarer medium for example from glass to air, the light travels faster and now bends away from the normal.

The normal is a line perpendicular to the boundary between the two substances.

32. Only a small percentage of the energyemitted by the Sun strikes Earth. Usea diagram to explain why.

Only a small Percentage of the energy emitted by the sun strikes earth because, since the earth is going in circles round and round, the sun only hits part of the earth and not fully. So for example if the earth is going around and the sun hits Africa then in a couple minutes it will go to the next country and that country will have sunlight.

What is the primary reason that astronomers put telescopes and other instruments above Earth's atmosphere? The instruments can better view the universe without the distraction of electromagnetic rays emitted by the earth. The instruments can get closer to the objects they are observing at the extreme ends of the universe. The atmosphere blocks or absorbs UV, gamma, and x-rays emitted by processes taking place in the universe. The atmosphere absorbs the infrared light coming in from the sun.

The main reason as to why those telescopes that are located above the Earth's atmosphere is because the atmosphere absorbs infrared light which comes from the sun and this affects the viewing done by the astronomers. That is why, this is considered as a great disadvantage for those ground-based telescopes. The answer would be the last option.

A laser beam is incident on two slits with a separation of 0.215 mm, and a screen is placed 5.45 m from the slits. an interference pattern appears on the screen. if the angle from the center fringe to the first bright fringe to the side is 0.183°, what is the wavelength of the laser light?

Use: dsin(θ) = mλ  where d is slit separation, m is fringe order (1 here), and 
θ = 0.183
Now λ = dsin(θ) /m = (0.215e-3)(sin(0.183))/1 = 6.867e-7 or λ = 687.7nm

Use: dsin(θ) = mλ  where d is slit separation, m is fringe order (7), and 
θ = tan⁻¹(0.028/1.1) = 1.458deg
Now λ = dsin(θ) /m = (1.6e-4)(sin(1.458))/7 = 5.96e-7 or λ = 596 nm

Given two positively charged particles, of equal magnitude, separated by a distance, "d". What will happen to the force field between the two particles when "d" is halved


C) increase by a factor of four


Electric fields, as well as charged particles, obey the law of attraction: opposite charges attract, like charges repel. Two positive particles would repel. If the distance between the particles is cut in half, the force field would increase by a factor of four. The electric field strength is inversely related to the square of the distance: "d" decreases by a factor of 2; multiply the original force by 4.

An expert archer tried to shoot an arrow into a target lying at the bottom of a shallow pool. Even though the water did not change the direction of the arrow, the archer missed the mark by several inches. Which interaction between light and matter caused the archer to miss the target?

Refraction is indeed the reason the archer missed.  When light passes from inside the water to the air outside, it bends causing the image of the target to appear to someone outside the pool to be in a different position.  This is due ultimately to the difference of electric permittivity between water and air.
