Yes. The earth's orbit is slowing down very gradually. This is due to a number of factors. Follow the Wikipedia links for more details.
no the length of day depends on the time of year.
The time taken by Callisto to orbit the Sun is essentially the same as the length of Jupiter's year: 11.86 earth years.

Because of the amount of sunlight changing from the earth being on its axis
The only thing the Earth orbits is the sun so the length of time it defines is 1 year. Hours, minutes and seconds were originally defined by the time it takes the Earth to spin on it's axis. One year can be expressed as hours, minutes and seconds but this time is gradually changing.
Changing the length will increase its period. Changing the mass will have no effect.
In Jupiter, time does not exist:D!
Typically, this length of time is called a "year". Each planet's year is a different length than that of the other planets and increases as the planet is further from the Sun.
Because that is not the length of the year. The length of the year is 365.2422 days.Because that is not the length of the year.

It is changing all the time it is currently at 53 million tourists a year!
Generally a year.

The length of time it takes to make a complete orbit around the sun.
