The problem states: Saturn is approximately 1.4x 10 to the 9th power kilometers from the Sun. If light travels at approx. 3.0 x 10 to the 5th power kilometers per second, how long does it take light from the Sun to reach Saturn? Express your answer in scientific notation.
The answers are: 4.7 x 10 to the 4th power, 4700 sec, 4.7 x 10 to the 3rd, or 47 x 10 to the 3rd.
I used the formula t=d/r
1.4 x 10 to the 9th power divided by 3.0 x 10 to the 5th power leaves 0.4666 x 10 to the 4th power.
I think the answer is 4.7 x 10 to the 3rd power. Is this correct?

The planet Neptune is approximately 4.5 * 10^9 kilometers from the sun. The planet Venus is approximately 1.1 * 10^8 kilometers from the sun. Which is the best estimate of how many times as far from the sun Neptune is as Venus? A.
One of Saturn's moons has an orbital distance of 1.87× 10m to the 8 power. The mean orbital period of this moon is approximately 23 hours. Use this information to estimate a mass for the planet Saturn.
Hi, this requires some basic knowledge of astrophysics. I missed last lecture that covered this, so though I'd prefer thorough solutions to these problems, I'd appreciate it even if you could tell me which formulas to use to solve
The average intensity of sunlight at earth's surface is approximately 1400 W/m^2 , if the Sun is directly overhead. The average distance between the earth and the sun is 1.50E11 m. What is the average power emitted by the Sun? Ok
