Determine whether a moving tennis ball and a racket held by the player have the same momentum or different momentum. If different, determine which object has more momentum.

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.

Ibelieve the answer is arteries

Ithink the answer for this is: an electromagnet is a magnet  with a soft metal core.
