Answer:
False.
Explanation:
We usually define vectors in terms of its magnitude and their orientation. Magnitude and direction does not vary with the change of a coordinate system as they are independent of coordinates and will remain the same. So it does not matter what your choice of a coordinate system is, it will not effect its direction and magnitude. However you can resolve the vector in to its components if you want.
Answer:
p_k=\sqrt{p_x^2+p_y^2}}
Explanation:
Apply the momentum in each direction knowing that the impact is at the same time for the pieces so




So the momentum in the other piece can be find knowing that

So:



To find the velocity knowing the mass



The answer is B . You begin with a purpose for the lab, then hypothesize on what you believe will happen. Next, follow the procedures. This is always the last step, Anatoly did. Reflect upon you hypothesis, did the lab support or disprove your hypothesis. Include observations you have made. Identify errors.
