One object is fired at an angle of ten degrees above the horizontal. a second object is fired at an angle of ten degrees below the horizontal, and a third is fired in an exactly horizontal direction. all three are fired at the same time, but with different (and nonzero) speeds. neglect air resistance and assume that the objects are fired over a perfectly level plain. which of the objects strikes the ground first?

The fired object at an angle of ten degrees below the horizontal

Explanation:

The second object strikes the ground first because independently of the magnitude of the speeds, this object has a speed component in the direction toward the floor allows it to reach the ground faster than the other objects.

Then the answer is:

The fired object at an angle of ten degrees below the horizontal

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.
