Momentum is a vector, although we don't hammer on that. In order to completely describe a momentum, you need a magnitude AND a direction ... just like force and velocity.
So choice #2 is the magnitude of a momentum, without its direction.
<em>Choice #3</em> is the full package, with both the magnitude and the direction.
Choice #1 has units of energy, and choice #4 has units of acceleration, so neither of those can be it.
Answer: Well there is a simple solution which is death..
The main difference between series and parallel circuits is that, in series circuits, all components are connected in series so that they all share the same current whereas. In parallel circuits, components are connected in parallel so that they all have the same potential difference between them
60mph= 26.8224 m/s
accelerationn= final velocity-initial velocity/time
