What are the difference between a red giant and a red super giant

So, unlike red giants, red supergiants are simply bright, red stars. It so happens that they may be in the same evolutionary state, but it is also possible that they have moved on. For example, most massive stars will appear as red supergiants while helium is fused into carbon in the core.



hope this helps you !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Red giants are very large stars which are highly luminous and have an inflated outer surface with an approximate temperature of about 5000 degrees K or lower.

Whereas, Red supergiants are the largest stars in the whole universe in terms of volume but they are simply bright, red stars unlike the red giants.

Having said that, there are no agreed theoretical distinctions between the red giants and red supergiants so there is still a room for confusion to discriminate between the two.

Please help! Is there another way that 3.40x10^-19J can be imputed on a computer. I have the right answer but it is wrong.

The energy of the photon with the wavelength of 584 nm is 3.4×10¯¹⁹ J

<h3>How to determine the frequency of the photon</h3>
  • Wavelength (λ) = 584 nm = 584×10⁻⁹ m
  • Speed of light (v) = 3×10⁸ m/s
  • Frequency (f) = ?

f = v / λ

f = 3×10⁸ / 584×10⁻⁹

f = 5.14×10¹⁴ Hz

<h3>How to determine the energy</h3>
  • Planck's constant (h) = 6.626×10¯³⁴ Js
  • Frequency (f) = 5.14×10¹⁴ Hz
  • Energy (E) =?

E = hf

E = 6.626×10¯³⁴ × 5.14×10¹⁴ Hz

E = 3.4×10¯¹⁹ J

The specific heat of aluminum is 0.125 cal/g °C. If 12.5 grams of aluminum were heated from 20.0 °C to 100.0 °C, calories of hea
klemol [59]
Aluminum does not undergo any phase change from 20.0°C to 100<span>.0°C, therefore we only consider sensible heat change, which is calculate as
</span>q = mc(dT)q = (12.5 g)(0.125 cal/g-°C)(100 - 20)<span>°C = 125 cal
</span>
Therefore, 125 calories of heat are absorbed by the aluminum.

Which two properties of an object are directly related to its thermal energy?
Levart [38]

Answer:

The answer is C

Explanation:

If we assume the sum of energy that could be obtained by absolutely transforming a unit of length, m. It is compared to the speed of light in this connection. In this case, the whole mass of the electron becomes force. In this, depending on the relation of Einstein, each electron can generate 510 keV, which is why only the option of "c" is right.
