The intensity of the radiation from the Sun measured on Earth is 1360 W/m2 and frequency is f = 60 MHz. The distance between the

Mama L [17]

Answer: (a) power output = 3.85×10²⁶W

(b). There is no relative change in power as it is independent from frequency

(c). 590 W/m²

Explanation:

given Radius between earth and sun to be = 1.50 × 10¹¹m

Intensity of the radiation from the sun measured on earth to be = 1360 W/m²

Frequency = 60 MHz

(a). surface area A of the sun on earth is = 4πR²

substituting value of R;

A = 4π(.50 × 10¹¹)² = 2.863 10²³×m²

A = 2.863 10²³×m²

now to get the power output of the sun we have;

P sun = I sun-earth A sun-earth

where A = 2.863 10²³×m², and I  is 1360 W/m²

P sun = 2.863 10²³ × 1360

P sun = 3.85×10²⁶W

(c). surface area A of the sun on mars is = 4πR²

now we substitute value of 2.28 ×10¹¹ for R sun-mars, we have

A sun-mars = 4π(2.28× 10¹¹)²

A sun-mars = 6.53 × 10²³m²

now to calculate the intensity of the sun;

I sun-mars = P sun / A sun-mars

where P sun = 3.85×10²⁶W and A sun-mars = 6.53 × 10²³m²

I sun-mars = 3.85×10²⁶W / 6.53 × 10²³m²

I sun-mars = 589.6 ≈ 590 W/m²

I sun-mars = 590 W/m²

The questionnaire evaluates five self-idea dimensions instructional, social, emotional, family, and physical which represent special qualities that might be differentially associated with distinct regions of human behavior, A person's self-concept allows them to define who they assume they're and the way they fit into the world. that in itself makes self-idea important due to the fact each person desires to realize themselves and experience as even though they belong.

1. Compare simple and compound radicals.

BARSIC [14]

Answer:

MARK BRAINLIEST PLEASE AND FOLLOW MY PAGE...thanks I luv u

Explanation:

Radicals are atoms that have an unpaired electron. They are very reactive and don’t exist for very long. If they react with a molecule, the products of the reaction will be a different molecule and a different radical. If two radicals react the product is a single molecule.

Ions have either gained or lost electrons to end up with a completed outer shell. They tend to strongly attract ions of opposite charge to make ionic compounds.
