If the earth rotated twice as fast as it currently does but its motion around the sun stayed the same would the length of the day change?
Interesting question. It depends on what time of day it was where you are when it reversed. If it was more than halfway through the light cycle of the day (sunup to sundown) then it would lengthen that perticular day assuming that the earth resumed the same speed of rotation that day but in the opposite direction. In other words if you have already gone through 8 hours of sunlight then you should get another 8 hours of sunlight for 16 total. If where you are has only gone through 3 hours of sunlight that morning then you will theoretically only get another 3 hours of sunlight as the sun was closer to the horizon and doesn't have that far to go before it sets again. Now here's the big clincher. If that happens then we all die and it won't really matter. The amount of gravity we have is dependant on the rotation of the earth. At the point of no rotation or even less rotation the gravity will change dramatically. God saw to it that everything on the earth was perfect for our survival. Speed of rotation, distance from the sun, temperature, atmosphere, etc... That is why there is no life (that we know of) on the other planets in our solar system.
The answer above by Freesinweasle is true, but I think the answer you are looking for is:
The question asks: How the lengeth of the solar day change?
Each time the Earth rotates around once on its axis, it moves a small distance along the its orbit around the Sun. Earth, therefore, has to rotate through slightly more than 360 degrees for the sun to return to the apparent location in the sky. Thus, the interval of time between noon one day and noon the next day(a solar day) is slightly grater than one true rotation period(one sidereal day). Our planet takes 365 days to orbit the Sun, so the additional angle is 360/365 = 0.986 degrees. Because Earth is rotating a the rate of 15 degrees per hour, takes about 3.9 minutes to rotate through this angel., the solar day is 3.9 minutes longer then the sidereal day(i.e, 1 sidereal day is roughly 23h 56m long). So the solar day would decrease by 7.8 minutes.

How would the solar day change if the earth rotated clockwise?
Provided the rotational speed was the same as it is now, the length of of the day would not change at all. Unfortunately though, there would not be any of us around that would survive such a shift. Too bad, it would really be nice to see the sun rise in the west and set in the east after the change.
How big is a trilobite?
Trilobites varied in size, with some species being as small as a few millimeters and others growing up to 70 centimeters in length. The average size of a trilobite was around 5-10 centimeters in length.
Why change in length is equal to original length?
When an object undergoes a deformation that does not cause it to break or permanently deform, the change in length can be equal to the original length if the deformation is elastic. This means that the object returns to its original length once the deforming force is removed, exhibiting a linear relationship between stress and strain. This behavior is described by Hooke's Law in the elastic region of a material's stress-strain curve.
What is length of an onion epidermis cell?
The length of an onion epidermal cell is typically around 0.2 to 0.5 millimeters.
What is the length of larynx?

Is it true that at the equator day length does not change?
yes. All the way around the equator the day length doesn't change.
Is length of an object a physical or chemical change?
The length of an object changing is a physical change, as it does not involve a change in the substance's chemical composition.
Does a isosceles trapezoid have rotational symmetry?
Yes, an isosceles trapezoid does have rotational symmetry. An isosceles trapezoid is a quadrilateral with two parallel sides of equal length, which means it can be rotated around its center by certain angles (180 degrees, in this case) and still look the same. This is an example of rotational symmetry, where the shape can be rotated and still appear unchanged.
Does muscle length change during isometric movements?
No, the length of the muscle fibers does not change. In isotonic movements is when the length changes.
What year did the observants change in terms of length?
The length of a year - the time it takes for a planet to complete one orbit around its star - has not changed in terms of Earth's orbit around the sun. It remains approximately 365.25 days.
How do you calculate percent change in length?
100*(New Length/Old Length - 1)
How do you change the size of a circle?

The type of contraction in which there is a change in the length of a muscle but no change in its tension?
Isotonic is the word you're looking for. Isotonic means the tension remains the same, but the length can change. Isometric means the length remains the same, but the tension can change.
How do you adjust perfect resolution for battlefield 3 on ps3?

What are the different types of logging?
There are currently three types of logging methods currently in use and they are Stem Only Harvesting (SOH) or tree-length logging, Whole Tree Logging (WTL) and finally cut-to-length logging.
How to calculate deformation in a material under stress?
To calculate deformation in a material under stress, you can use the formula for strain, which is the change in length divided by the original length of the material. This can be represented as L / L, where is the strain, L is the change in length, and L is the original length of the material. By measuring the change in length and the original length, you can determine the deformation of the material under stress.
