Answer:
There always is an acceleration in a curvilinear motion, as the velocity vector changes, so always.
At some time during her drive she backed up with a substantial negative. ( backwards) acceleration. Since the pocket book is not physically connected to the seat it is free to move. Upon rapid negative acceleration the pocket book remains in its position while the car accelerates backwards away from it. this demonstrates Newtons 1st law of motion. The first law is the law of inertia. Which states, an object at rest. ( pocketbook) will remain at rest and an object in motion will continue in motion at constant velocity, unless acted upon by some outside force to change its motion.
It can never be shorter than a component - magnitude of a vector is the square root of the sum of the components squared, and a square function never produces a negative number. However, it can be the same size as it's component, if that component is the only one.
Answer:

Explanation:
We have given torque 
Initial time 
Final time 
There is relation between angular momentum and torque
that is 


Answer:
it's a transverse wave
Explanation:
cuz its going perpendicular
