Am I right in saying that this is the correct proportionality for luminosity and mass in a star?
If it is, i am confused. In an example I have it states that when mass is doubled the luminosity...
Homework Statement
I have to calculate the lifetime of a star that is 300,000 times as luminous as the sun and 24 solar masses.
Homework Equations
lifetime = k * m/l
The Attempt at a Solution
lifetime = 10^10 * (24/300000)
lifetime = 800000 years
I feel as if this is...
Thanks Bruce
The thing is, I am confused as to what the energy conversion is when the toy is placed on the table. Is it chemical potential energy or gravitational potential energy? That is what is confusing me.
