There would be [182 and 5/8] days in a year; each day would be 48 hours long.
earth would go out in the solar system
The length of the day
It would depend on the degree and time frame of change and how that change was brought about. The rotation of the earth is very slowly changing. It is slowing down.
The acceleration will be doubled accordingly. From 10m/s2 to 20.
As an example: 4 x 5 = 20, when doubled only once, it is 8 x 10 = 80

The primary thing which happens if there is no rotation or revolution is that the Earth loses its seasons. One side of the planet will bake in the Sun while the other freezes from a lack of sunlight.
Umpteen millions even if it could ever happen.

The earth rotation
Momentum = mass x velocity. So if the velocity is doubled, momentum will be doubled as they are directly proportional to each other.
When will the revolution which major speaks about happen
If both dimensions are doubled then the area is quadrupled. This is true of any geometric shape.
If the potential difference between the ends of any conductor is doubled, then the current through the conductor is also doubled.
Crisis on Infinite Earths happened in 1919-04.
