Question

I need to find the luminosity using the equation L=F×4πd ² . The answer should look like L=7.71×10²⁵W.

a. L= 7.71/4π×10 ²⁵

b. L=7.71×10²⁵

c.L= 7.71×10/4π²⁵

d. L=4π×7.71×10 ²⁵

Answer 1

The luminosity of a star can be calculated using the equation L = F × 4πd².

Step-by-step explanation:

The luminosity (L) of a star is given by the equation L = F × 4πd², where F is the energy flux and d is the distance. In the given equation, L=7.71×10²⁵W, which represents the luminosity of the star. So, the correct answer is b. L=7.71×10²⁵.
