<em>Here's an example letter.</em>
Dear Shenn,
How are you? I haven't heard from you in months. I trust you're well. I'm hoping we could meet this coming Christmas season.
I've recently transferred to another school this semester, and I'm really enjoying it. I'm now on my second year in high school. We have a lot of homework and it has been keeping me busy. Are you also busy in school?
On weekends, I spend time with my family and a new family member, Dobbie. No, he's not my brother. He's a Golden Retriever that I've been asking my dad for a very long time. My parents taught me how to take care of him because they say it would teach me responsibility and independence. Honestly, having a dog is not all fun and games. I sometimes feel exhausted, but I'm blessed that my mom loves dogs too; so we take turns taking care of him.
Before I forget, I'd like to invite you over this Christmas eve. My family will be hosting a party at home and we're very much excited to have you as one of our guests.
I'm looking forward to your reply. I hope you and your family are in good health. Do give them my regards.
Sincerely,
<em>Your Name </em>
Answer:
Two stars (a and b) can have the same luminosity, but different surface area and temperature if the following condition is met:
(T_a^4)(R_a^2) = (T_b^4)(R_b^2)
Explanation:
The luminosity of a star is the total energy that produces in one second. It depends on the size of the star and its surface temperature.
L = σ(T^4)(4πR^2)
L is the luminosity f the star, T is the temperature of the surface of the star and R is its radius.
Two stars can have the same luminosity if the relation between the radius and the surface temperature is maintained.
To see this lets suposed you have 2 stars, a and b, and the luminosities of each one of them:
L_a = σ(T_a^4)(4πR_a^2)
L_b = σ(T_b^4)(4πR_b^2)
you can assume that L_a and L_b are equal:
σ(T_a^4)(4πR_a^2) = σ(T_b^4)(4πR_b^2)
Now, you can cancel the constants:
(T_a^4)(R_a^2) = (T_b^4)(R_b^2)
as long as this relation between a and b is true, then the luminosity can be the same.
