Question

If L = 6.1 × 1030 W and
F = 4.4 × 10–10 W m−2,
find d in the equation d = square root of (L over (4 Pi F))
You should give your answer in scientific notation, with the correct number of significant figures and the correct SI base units.

Answer 1

I hope this answer is helpful for you

Answer 2

Answer:

The required answer is 1.1037 x 10³⁹ m⁻¹

Step-by-step explanation:

It is given to us that :

L = 6.1 x 10³⁰ W

F = 4.4 x 10⁻¹⁰ W m⁻²

also it is provided that the relevant formula is :

d = $\sqrt{\frac{L}{4 * 3.14 * F} }$

where π = 3.14

Therefore d = $\sqrt{\frac{6.1*10^{30}}{4*3.14*4.4*10^{-10}} }$

or, d = 1.1037 x 10³⁹ m⁻¹

Here , it has been asked that the answer should be in scientific notation and with correct significant figures and the correct SI unit

Hence the SI unit is meter inverse, significant figures is 1.1037 (correct up to 5 significant figures)

Therefore, the required answer is 1.1037 x 10³⁹ m⁻¹
