Earth would not be the same is the sun were replaced with a star with twice as much mass. There would be climate changes, changes in daytime and night time, which would offset almost everything.
Depends what you mean with "the same". To continue at the same distance from the Sun, Earth would have to move quite a bit faster.
If the sun was replaced by a star with twice as much mass the gravitational force would be unbalanced and the new sun would burn the earth because if the gravitational force cannot hold than the sun would plummet towards the earth and burn it.
Mars has roughly twice the Earth's period of revolution.
None, because only half an Earth can fit inside of Mars.
About twice the distance you could on earth. You could jump much further if you didnt have to wear a spacesuit. Maybe we can have a Lunar Olympics someday if we make an atmosphere for the moon like we have here on earth.

I suppose you could use -42 twice. -63 and -21
twice a year
If Earth had twice as much oxygen as it does, fires would start easier and burn hotter. Arthropods (insects, spiders and the like) could be a good deal larger than they are now.

Check your lower radiator hose. Alot of times you cant tell its leaking from there. Ive replaced mine twice. Check your lower radiator hose. Alot of times you cant tell its leaking from there.

Mars has an orbital period of very approximately twice that of the earth
No, its smaller than the Earth.
the curving of the path would curve more than it is suppose to and the straight path due to the earths rotation would no longer be straight
try your thermostat
