Question:
The radiant flux intensity F of light from a lamp at a distance of 10 cm is 0.32 W m−2. Calculate F from the same lamp at a distance of 15 cm. State any assumption(s) you make.
Where necessary, take:
L⊙ = 3.83 × 1026 W
1 ly ≈ 9.5 × 1015 m

I have been a tutor for the past 5 years. I have experience working with students in a variety of subject areas, including computer science, math, science, English, and history. I have also worked with students of all ages, from elementary school to college. In addition to my tutoring experience, I have a degree in education from a top university. This has given me a strong foundation in child development and learning theories, which I use to inform my tutoring practices.
I am patient and adaptable, and I work to create a positive and supportive learning environment for my students. I believe that all students have the ability to succeed, and it is my job to help them find and develop their strengths. I am confident in my ability to tutor students and help them achieve their academic goals.
