The magnitude of the change in momentum of the block between zero and 4. 0 seconds is
dp=1.6m/s
<h3>What is the magnitude of the change in momentum of the block between zero and 4. 0 seconds?</h3>
Generally, the equation for the kinematics equation is mathematically given as
x=x+ut+0.5at^2
Therefore
1.6=0+0+0.5*a*1^2
a=0.2m/s^2
In conclusion, change in momentum
dP=mv-mu
2.0*0.8-0
dp=1.6m/s

The earth is so round that we can run around it in five million days
Answer:
The sympathetic nervous system _____decelerates_______digestion and __accelerates___________blood pressure. See the explanation below, please.
Explanation:
The sympathetic nervous system together with the parasympathetic make up the autonomic nervous system. The sympathetic system acts in situations of stress, prepares the body for "fight or flight", increases heart rate and blood pressure at the cardiovascular level, at the digestive level it slows down the system, produces bronchodilation, pupil dilation (mydriasis).
26).
The complete pattern of a pendulum is ...
-- out to one side
-- back to the center
-- out to the OTHER side
-- back to the center.
So, on the graph, the complete period is one up-loop and one down-loop.
That's <em>6 seconds</em>. (b)
27).
This question is just asking for the frequency, without using the word.
Frequency is always (1/period). That's <em>1/6 of a second</em>. (a)
(This kinda makes sense. If you want to do something in 6 seconds, you need to do 1/6 of it every second. Right ?)
