About 1,360 watts per square meter
At Earth's average distance from the Sun (about 150 million kilometers), the average intensity of solar energy reaching the top of the atmosphere directly facing the Sun is about 1,360 watts per square meter, according to measurements made by the most recent NASA satellite missions.

Answer:
the answers the correct one is d
Explanation:
The speed of sound is constant so we can use the relations of uniform motion
v = x / t
x = v t
now let's calculate the distance for each person
t = 5s
x₁ = 300 5
x₁ = 1500 m
t = 6s
x₂ = 300 6
x₂ = 1800 m
therefore we have two possibilities
a) the two people are on the same side, therefore the distance between them is
Δx = x₂- x₁
Δx = 1800 - 1500
Δx = 300 m
let's reduce to km
Δx = 0.300 km
b) people are on opposite sides of the sound
Δx = x₂ + x₁
Δx = 1800 + 1500
Δx = 3300 m
Δx = 3.3 km
when checking the answers the correct one is d
The first part of the question is 3,100 V.
The second part of the question is 200 V.
