If the Sun is a distance of 1.5 times 108km from Earth how long does it take sunlight to reach Earth if it moves at 3.0 times 108ms?

60 seconds = 1 minute
time = distance/speed
= (1.5 × 10⁸ km) / (3.0 × 10⁸ m/s)
= (1.5 × 10⁸ × 10³m) / (3.0 × 10⁸ m/s)
= 500 s
= 500 ÷ 60 minutes
= 8⅓ minutes = 8 minutes 20 seconds
≈ 8.33 minutes

How does radiation warm the earth?
By the sunlight, when the sunlight enter in the earth
How many minutes does the sunlight touch the earth surface?
Sunlight is constantly touching the earth's surface. It never stops. (we hope)
How is sunlight transformed to earth?
by a chicken
What is the distance between earth and heaven?
The same as between the Moon and the Earth. The distance from the clouds to the surface of the Earth is insignificant, compared to the Moon-Earth distance.The same as between the Moon and the Earth.

Main source of energy on the earth?
Sunlight is the main source of energy on earth
How much more sunlight on Mars than on Earth?
Mars gets LESS sunlight than Earth does, because of its greater distance from the Sun.
What is is the earth distance from the sun?
An average of 93 million miles. It takes sunlight 8 minutes to arrive at the Earth's surface.
Why from a distance earth would be the brightest of the nine planets?
This is because sunlight is reflected by the planet's water
How much sunlight does satern get?
Saturn's average distance from the Sun is about 9.582 AU; that means that it gets about 1/92 of the sunlight, per square meter, that Earth receives.
What's the ammount of sunlight that falls on a square meter of earth with a latitude of 48'?
The amount varies with the season. These affect the earth's inclination as well as its distance from the sun.
How many seconds does it take sunlight to reach earth?
With the average distance or "mean" distance from the Earth to the sun set at approximately 93,000,000 miles, and the speed of light at about 186,000 miles per second; the time in seconds it takes sunlight to reach the earth is appoximately "500 seconds". Most people refer to the time in minutes which would be about 8.333333 minutes.
Do aphelion and perihelion affect sunlight hitting the earth?
Only very slightly. The Earth's orbit is nearly circular and sunlight diminishes with the square of the distance, so if the Earth were 1% farther at some times, those times would only see sunlight reduced by a factor of 0.0001 (0.01%). Much more significant is the angle the hemispheres present to the Sun's rays as a result of the Earth's inclination (about 22 1/2 degrees). When the ground is tilted away, the sunlight is spread over a larger area and so delivers less energy per unit of area. This, and not the distance from the Sun, is what causes winter.
How do you explain the effects of the sunlight striking earth?
explain the effects of the sunlight striking earth
What happens to the sunlight that hits the surface of the Earth?
Sunlight that hits the Earth's surface is absorbed by the Earth. It is then reflected back.
How the earth is heated and what affects the way the earth is heated?
the earth is heated by the sunlight and it affects it by it being too hot when the sunlight is shining on earth.
What is the percentage of sunlight reflected by the earth's surface?
On average the earth reflects about 30% of the incident sunlight.
