Each point along the track of one solar mass star represents the star's surface temperature and luminosity at one time.
<h3>What is the one-solar mass star?</h3>
A star having a mass equal to the mass of the Sun is called a one-solar mass star.
Its life track shows the luminous intensity as well as the surface temperature.

Problem 2
Answer: Choice D only
Explanation:
Let's go through the list of possible answers
- A) She only would feel a force pulling her toward the chair, hence making her feel heavier, only when the space ship is accelerating faster. In this case, she is moving a constant speed of 0.5c (aka half the speed of light). Despite going this fast, she is moving at a constant speed and therefore not accelerating at this current time. The speed isn't changing. Therefore, she would not feel a force pushing her into the chair. Choice A is off the list.
- B) This is also off the list as well. The lack of accelerating force means her lungs aren't compressed and breathing should be normal. This is assuming she doesn't have any medical conditions hindering her breathing. We can cross choice B off the list.
- C) This is similar to choice B. We can cross it off the list.
- D) The faster you go, the more time dilation will occur. This effectively compresses time and makes it slow down. The more detailed explanation involves relativity which is very complicated. Therefore, choice D is the answer.
- E) This is false because choice D was mentioned to be true.
Answer:
Potential difference across resistor will be 87.66 volt
Explanation:
We have given number of electrons
Charge on one electron
So total charge
Time is given t = 5 min
1 minute = 60 sec
So 5 minute = 5×60 = 300 sec
So current
Resistance is given R = 40 ohm
Sp from ohm's law potential difference across resistor v = iR = 2.1866×40 = 87.466 volt
Answer:
The answer is Low earth orbit
White dwarf is white and dim
