What would be the shorter if earth rotated faster?
second, minute, hour, day, month, year!
How the earth would be different if there was no moon?
Without the moon, Earth would spin faster. Our day would be shorter. Billions of years ago, Earth spun around on its axis much faster. Our world's cycle of day and night was less than ten hours long. The ebb and flow of the tides are what put the brakes on Earth's spin. The moon and sun together cause the tides. If we'd never had a moon, we'd still have tides, but they wouldn't be as strong. So - if you're imagining Earth with no moon - you have to imagine our day on Earth much shorter than our present-day 24 hours.
What would happen if it took Earth longer to rotate?
Our days would be longer for a start, darkness would fall more slowly and the night would last longer. The surface temperature range would also be greater, as more time during the night would allow the surface to cool more, while longer days would cause it to heat up more. this may well impact on weather conditions. The Earth did actually spin faster many years ago, but has gradually slowed down over time thanks to the drag caused by the moon.
How would the tides on earth be differrent if the moon revolved around earth in 15 days instead of 30 days?
In that case, the Moon would have to be much closer to Earth (you can calculate the distance using Kepler's Third Law); the tides would be much stronger.
If the earth was closer to the sun would days become longer or shorter?
Yes they would. Indeed in past Geological times (eg the Devonian era), there were 404 days in the year. This was because the Earth was spinning a loft faster then. What slows the Earth's spin is the pull of the Moon on Earth's Oceans. This cause the Moon to speed up (recede form the Earth) and the Earth to slow.
What happens if the Earth spun faster?
The days would be shorter.
If the earth revolved around the sun at a faster rate than 30 km how would the length of a year on earth be different?
I assume you mean 30 km/second - that's more or less the speed of Earth around the Sun. Unless you want to change the mass of the Sun, this is only possible if Earth gets closer to the Sun. That would make temperatures on Earth higher, and years shorter.

Would the Earth's period of revolution about the sun be shorter than 1 year if it was closer to the sun than 1 au?
If it still revolved the same speed Yes.
Why would another planet have a shorter day than earth?
It's to do with the length of time a planet takes to spin, a planet that spins on its axis faster than the earth will have a shorter apparent day.
How would the tides on earth be different if the moon revolved around earth in 15 days instead of 30?
If the moon moved around the earth faster, while the earth maintained the same rotational speed, the period between spring and neap tides would be less.

What would stay the same if earth rotated and revolved in the opposite direction?
Everything The sun provides for earth
