Physics And Measurement Question 239
Question: The solar constant is defined as the energy incident per unit area per second. The dimensional formula for solar constant is
Options:
A) $ [M^{0}L^{0}T^{0}] $
B) $ [ML{{T}^{-2}}] $
C) $ [ML^{2}{{T}^{-2}}] $
D) $ [ML^{0}{{T}^{-3}}] $
Show Answer
Answer:
Correct Answer: D
Solution:
[d] Energy incident per unit area per second $ =\frac{Energy}{area\times \sec ond}=\frac{ML^{2}{{T}^{-2}}}{L^{2}T}=M{{T}^{-3}} $
