Answer:
Yes it is possible to charge balloon to several thousand of volts and the balloon will also store several Joules of energy.
Explanation:
By rubbing a balloon on one's hair or on different types of clothing, the balloon either gain or loss electron.
If the balloon gains electron it becomes negatively charged, it contains more electron and subsequently charged to several thousand volts.
Also, if the balloon losses electron, it becomes positively charged. In this case it contains more proton, which makes the balloon positively charged to several thousand volts.
However, amount of joules depends on volts produced in the balloon.
Volt = Joules/coulomb,
Joules = volts*coulomb
Because the charge of the particles (electron and proton) are small, amount of joules will always be small than volts.
So, it is possible to charge balloon to several thousand of volts and the balloon will store several Joules of energy
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

So, you know how to add, right? Subtraction is just taking the negative one, making it the other direction, and then adding the two in the proper order. So, for example, a 1.00 cm long vector 45 degrees above the x-axis, and the same below it (let the first be a and the second be b, and have both be directed away from the origin). A-B in that case would be the square root of 2, at 90 degrees off the x-axis. The first file I attached was the regular adding, and the second was the subtraction.
Answer:
.
Explanation:
The box is sliding with a constant speed in a fixed direction (to the right.) In other words the velocity of this box is constant. Hence, this box would be in a translational equilibrium. The acceleration of this box would be zero.
By Newton's Second Law of motion, the net force on this box would be . In other words, forces on this box are balanced.
The question is asking for the size of the friction on the box. Assuming that the floor is horizontal. The friction on this box would also be horizontal,
The only other force that could balance that friction would be the push to the right. The direction of this push is horizontal (to the right.) Hence, the entirety of that would be in the horizontal direction.
Thus, forces on this box in the horizontal direction would be:
- The push to the right.
- Friction that opposes the rightward motion of the box (that is, to the left.)
Since these two forces must balance each other, the size of the friction would also be .
