PLEASE HELP!! Mercury is the closest planet to the Sun, with an average distance of 35,000,000 miles. It takes
light about 3 minutes to travel from the Sun to Mercury.
Neptune is the farthest, with an average distance of 2.8 x 10 miles from the Sun.
How many times farther from the Sun is Neptune than Mercury? How long does it take light to
reach Neptune? Follow the steps to find out.

1. Write the distance from the Sun to Mercury in scientific notation. Include units with your answer.

2. Write and simplify an expression showing how many times farther Neptune is from the Sun than Mercury. Write the result in scientific notation.

3. How many times longer does it take light from the Sun to reach Neptune than Mercury? Express this number in standard notation. Explain your reasoning.

4. It takes light from the Sun about 3 minutes to reach Mercury. How many hours does it take light from the Sun to reach Neptune?

Asmall (but heavy) particle placed in a glass of water will follow a zigzag motion because the particle will bounce off of the water molecules it meets. this is called brownian motion. a physicist simulates this on a computer, by varying the distance a particle can travel (called the mean free length), on average, before it collides with a water molecule and assigning the change in motion to be one of 8 directions, each with a similar probability. by running the simulated particle (with the same mean free length) many times she determines that it should take 15 seconds, on average, for the particle to fall to the bottom, with a standard deviation of 1.5 seconds. next she lets a real particle fall through a glass of water and finds that it took 18 seconds. what does she conclude, and why?
