This is an unanswerable question based on the information you have given. The tidal forces cause the Earth to rise as well as the water. The difference in height of the water will depend on the depth of the water as well as local geography. Some of the highest tides in the world are in the Bay of Fundy between Nova Scotia and New Brunswick (50 feet). It has less to do with the strength of the moon's gravity at that point and much more to do with the frequency of the tidal oscillation and natural period of the bay itself and the shape of the Minas Basin.bjon-07 said:Hi all, I am reviewing for my final and cannot seem to find how to solve the following
If the tides on Earth one meter high how far away is the moon?
What equations should I use to calulate how the moon effects the tides on earth?
I calculate the answer to be 23 hours 56 minutes.bjon-07 said:OK here is the exact question he gave in class,
If the tides are a meterhigh, how long will you birthday be next year?
Well how accurate do you want it to be? 86164.091 seconds or 23 hours 56 minutes 4.091 seconds: that is the length of an Earth day. It increases a few microseconds per century due to the Earth losing angular momentum to the moon but that is all.bjon-07 said:Thanks for the help Andrew. Could you please show me how got the anwser 23 hours 56 minutes.
I know as the moon moves away from the Earth the Earth is slowing down. Some of the angular momnet of the Earth is "lost" on the moon.
You can't. You have to measure it. It is way too complicated to predict mathematcally.bjon-07 said:thanks for the quick reply. I understand that the change will be minimal but how can i mathmatically show how much angular momentum is lost on the moon each year.
The tides on Earth do not directly affect the distance of the Moon. However, the gravitational pull of the Moon does cause tides on Earth as the Moon orbits around the Earth.
No, the distance between the Earth and the Moon varies due to the elliptical shape of the Moon's orbit. The average distance between the Earth and the Moon is about 384,400 kilometers.
Scientists use a technique called Lunar Laser Ranging to measure the distance between the Earth and the Moon. This involves sending a laser beam from Earth to reflect off mirrors on the Moon and measuring the time it takes for the light to return.
No, the tides on Earth would not have a significant impact on the distance of the Moon. The gravitational pull of the Moon would remain the same, and the tides would simply be higher due to the increased pull on the Earth's oceans.
The distance of the Moon from the Earth does have an effect on the tides. When the Moon is closer to the Earth, the gravitational pull is stronger and the tides are higher. When the Moon is farther away, the gravitational pull is weaker and the tides are lower.
