Probably not, except in the movies. The boomerang "returns" (not all do) because of special airfoil surfaces, which the "batarang" does not appear to have.

Could a fly 'fly' in a vacuum?

No, a fly would not be able to fly in a vacuum because it relies on air resistance and pressure to generate lift and maneuver in the air. In a vacuum, there would be no air molecules for the fly to interact with, so it would not be able to fly.


Would a fly flying inside an aeroplane add to its weight?

No. A fly hovering above you doesn't make you feel heavier does it? Although you probably would'NT feel it anyway.


How would you explain this You are riding in a car at 80kmh A fly trapped in the car rests on your shoulder Describe the speed of the fly using two different reference points?

The fly is motionless, compared to your shoulder or the rear-view mirror. The fly is traveling at 80 km/hr with reference to the street signs on the side of the road. Assuming that traffic is going 80 km/hr each way, the fly is traveling at 160 km/hr with respect to the oncoming traffic in the other lane.


What speed would a fly with a mass of 0.55g need in order to have the same kinetic energy as the automobile in item 19?

The mass of the fly is 0.55g, or 0.00055 kg. The kinetic energy of the automobile in item 19 would need to be calculated first, then set equal to the kinetic energy of the fly. Solving for the velocity of the fly using the equation ( KE = \frac{1}{2}mv^2 ) would give the speed needed for the fly to have the same kinetic energy as the automobile.


Flying from Wisconsin to Florida in a straight line what is the fewest number of states over which you would travel?

4: Indiana, Kentucky, Tennessee, Alabama. You would need to fly from Sturgeon Bay, WI (to miss Michigan) and fly to Pensacola, FL. Of course, you could fly north and hit Michigan's upper peninsula while you almost completely circumnavigate the earth and hit Florida in Key West. That would be 1 State you would fly over. The definition of "state" comes into play on this answer, though. By one definition, a "state" is a country. Another way to answer this is to say that you cannot fly in a straight line from Wisconsin to Florida because your plane cannot bore through the curvature of the earth and must follow an arc.
