What evidence do you have that waves with short wavelengths and high frequencies also have high energy?
When we made waves with the slinky, it too much more energy to make short waves with high frequencies.

How do you change distance in km to astronomical units?
Convert it to scientific notation, then divide by 150 x 10E6.
500
Which scientist suggested that planets traveled in an elliptical path around the sun?
Kepler

What are Keplers 3 laws of planetary motion?
1. Planets have elliptical orbits
2. the closer a planet is to the sun, the faster it moves.
3. There is a ratio for the length of the orbit and the distance from the sun.
