(note: this answer is mostly from my star knowing bro who can't get online right now)
The temperature of the star only has to do with the color of the star, not how much light it gives off (according to the HR-diagram (google it)). The amount of light it gives off is determined by its surface area, the more surface are it has, the more light it gives off.
lets talk about the options
A. neutron stars: extremely dense (heavy) stars, that have blown up and only have their extremely dense core left. and this is wrong since it does not do thermonuclear fusion and therefor does not emmit its own light except when it swallows something and gets brighter and hotter as a result
B. Black holes: neutron stars that have a mass greater than 3 solar masses. these 'stars' have so much gravity, that do not let light to escape, so it does not have much tempurature and all light is sucked in and not released in a visible form
C. Giants:either middle sized stars that are entering their last stages of their lives, or huge main sequence stars. They behave the same way as main sequence stars in that the bigger the surface area of the star, the more light it gives off, and the tempurature determines the color not the amount of light
D. Main sequence stars: same as giants
we can eliminate main sequence stars and giants because they are the same but different sizes.
we can eliminate black holes because they don't let light to escape
therefor the asnwer is A. neutron stars
ANSWER
A. NEUTRON STARS
Answer:
93 billion light years
Explanation:
The proper distance—the distance as would be measured at a specific time, including the present—between Earth and the edge of the observable universe is 46 billion light-years (14 billion parsecs), making the diameter of the observable universe about 93 billion light-years (28 billion parsecs).
Answer:
The correct answer is C. <em>Greater throcanter of the femur.</em>
Explanation:
Hip fractures describe all those fractures that occur in the proximal extremity of the femur.
According to the location of the fracture in the extremity, it can affect the femoral head, the femoral neck, the trochanter of the femur or the area under the femur.
Most of the hip fractures occur in older people, mostly in women, and mainly, the causes of fractures are falls or missteps.
For the treatment, there are some surgery options, among other more conservatory. One of them is <u>hip pinning</u>, which is considered a good option for fractures that occur in the<u> greater and lesser part of the trochanter</u> in the femur bone.
The answer is 6.41 hope this helps
