1. You're rotating the image about a plane I think I remember
2. Larger
3. 600 miles
4. They're ferromagnetic so magnetize them both by keeping them near each other. Boom we're done here
5. Stay the same
6. Fall since it doesn't have to displace a mass of water (less dense) equivalent to the nuts and bolts (more dense)
7. Assume the pigeons begin at the top of the cab with zero initial momentum and we allow them to fall while the truck begins to accelerate. The truck would feel lighter and accelerate more easily up until the point where the free-falling pigeons contact the back of the truck and begin to be accelerated by the truck.
8. It moves in the direction of the car since the air in the vehicle is a fluid mass that piles up in the car opposite the direction of acceleration.
9. 30 seconds isn't enough to fully explain, but there's a separate solution to the field equation inside versus outside. Inside it should float where it is as attractive forces balance themselves out.
10. Mass of the liquid = mass of the can let's go with that
No guarantee I read the questions correctly in the 30 seconds I gave myself for each
