P = m*v
conservation of momentum suggests
initial momentum equals final momentum
mv-initial = mv-final
(0.0010 kg)(50 m/s) = (0.0010 kg + 0.35 kg)v
thus:
v = (0.0010)(50)/(0.351) = 0.142 m/s
Answer: C. Acceleration
Explanation:
Acceleration is defined as the variation of Velocity in time :
In addition, acceleration is a vector quantity (like velocity) and as a vctor it has magnitude and direction. <u>When one of this aspects changes (or both) acceleration changes as well.</u>
So, if the car keeps the same speed () but changes its direction, its acceleration changes.
Answer:
D. Synthetic polymers are inexpensive to produce.
Explanation:
Hailey should include that synthetic polymers are inexpensive to produce as a benefit of synthetic polymers.
Synthetic polymers are artificially produced. These polymers come about from petroleum oil. Their hydrocarbons are industrially worked to produce the long chain hydrocarbons to form polymers.
Most of these polymers are very cheap to produce and does not cost too much. This is why they almost found everywhere.
