Answer:
The meaning of the integral (120, 60)∫ |v(t)| dt is simply the distance covered by the particle from time t = 60 seconds to time t = 120 seconds
Explanation:
We are told that the particle moves back and forth along a straight line with velocity v(t).
Now, velocity is the rate of change of distance with time. Thus, the integral of velocity of a particle with respect to time will simply be the distance covered by the particle.
Thus, the meaning of the integral (120, 60)∫ |v(t)| dt is simply the distance covered by the particle from time t = 60 seconds to time t = 120 seconds
U=0
<span>t=10 </span>
<span>a=9.8m/s/s </span>
<span>v is velocity (the tower must be very high to be able to fall for 10 seconds!!!) </span>
<span>you work out the result now</span>
C. It must be able to be supported or fefuted by data
The chartjunk allows you to find unnecessary elements in the chart,
- lines on the horizontal grid
- values in numerous at each point
Understanding the exercise is easier with a graph. See attached
The graphical representation of a set of values saves a lot of time in the data analyst, it is called chartjunk to all the unnecessary elements in a graph that do not help to understand the information represented or that are a distraction for the observer.
In the case presented we have a scatter plot with the x-axis the year of the computer and on the y-axis the number of units in millions, the graph shows two data sets the number of computers and the number of them with access to the internet depending on the year.
The lines in the horizontal grids are excessive represents chartjunk, since it does not help to understand the relationship between the data presented
Computer symbols are shown in the legend and the data to be plotted, this is important information, but in the graph at each point the values are shown in a distracting element since it is in the table and is unnecessary, therefore it's a chartjunk
A missing piece of data in the graph is a connecting line between the total number of computers.
The chartjunk allows you to find unnecessary elements in the chart,
- lines on the horizontal grid
- values in numerous at each point

Answer:
Momentum
Explanation:
Heisenberg uncertainty principle says it is <em>uncertain to find the momentum and position of a particle at the same time. there must be some uncertainty.</em>
.
It means decreasing the position value will increase the momentum value while decreasing the momentum value will increase the position value.
I hope it works for you
Thank you.
