The colour of star depend on its temperature, why?​

Physics
1 answer:
taurus [48]2 years ago
4 0

<em>Another key factor that determines a star's colour is its temperature. As stars become hotter, the overall radiated energy increases, and the peak of the curve changes to shorter wavelengths. To put it another way, when a star heats up, the light it produces moves toward the blue end of the spectrum.</em>

Does the rankine degree represent a larger or smaller temperature unit than the kelvin degree
zvonat [6]
The best and most correct answer among the choices provided by the question is the first choice, larger.

Rankine is Fahrenheit + 460 , while Kelvin is Celsius + 273. We all know that Fahrenheit has larger number compared to kelvin , thus rankine is much larger.

asambeis [7]
Alfred Wegener believed that all of the continents were originally attached! By looking at the map, you can see that Africa and South America look like they were once joined. This 'super continent' was known as Pangaea. He also found fossils that proved his point.
Hope this helps :)

Imagine you are holding an apple. Does this apple have energy?how do you know?
patriot [66]

The apple in my hand has three different forms of energy
that I can think of.

1). Thermal energy.  I know that the apple's temperature is
not absolute zero, because it is not freezing my hand off. 
Therefore it holds some heat energy.

2).  Chemical energy.  From previous experience, I know that
if I eat the apple, it gives me a boost and keeps the doctor away,
since my  body is able to metabolize it, and extract nutrition from
its chemical energy.

3).  Potential energy.  Also from previous experience, I realize
that when I picked up the apple, I exerted force on it opposite to
the force of gravity.  By doing work on it, I endowed it with increased
gravitational potential energy, which would immediately be obvious
if I dropped it to the ground, where it would either smash or dig a
little crater in the grass.

A 20 N force causes an impulse of 500 N*s. How long was the force applied for?
yKpoI14uk [10]

Answer:

25sec

Explanation:

Impulse = Force * time (period)

therefore,

500N*s= 20N * x(secs)

divide both sides by 20

results in  500/20=x

x= 25 secs
