We are manipulating one-variable statistics.
To begin:
Turn on the calculator.
Access statistics mode.
Select
<4:ClrList> to clear data from lists, if desired.
,
Enter list
[L1] to be cleared.
,
[L1] ,
Display last instruction.
,
[ENTRY]
Continue clearing remaining lists in the same fashion, if desired.
,
,
[L2] ,
Access statistics mode.
Select
<1:Edit . . .>
Enter data. Data values go into
[L1] . (You may need to arrow over to
[L1] ).
Type in a data value and enter it. (For negative numbers, use the negate (-) key at the bottom of the keypad).
,
,
Continue in the same manner until all data values are entered.
In
[L2] , enter the frequencies for each data value in
[L1] .
Type in a frequency and enter it. (If a data value appears only once, the frequency is "1").
,
Continue in the same manner until all data values are entered.
Access statistics mode.
Navigate to
<CALC> .
Access
<1:1-var Stats> .
Indicate that the data is in
[L1] ...

[L1] ,
...and indicate that the frequencies are in
[L2] .

The statistics should be displayed. You may arrow down to get remaining statistics. Repeat as necessary.
Drawing histograms
Note
We will assume that the data is already entered.
We will construct two histograms with the built-in STATPLOT application. The first way will use the default ZOOM. The second way will involve customizing a new graph.
Access graphing mode.
,
[STAT PLOT]
Select
<1:plot 1> to access plotting - first graph.
Use the arrows navigate go to
<ON> to turn on Plot 1.
<ON> ,
Use the arrows to go to the histogram picture and select the histogram.
Use the arrows to navigate to
<Xlist> .
If "L1" is not selected, select it.
,
[L1] ,
Use the arrows to navigate to
<Freq> .
Assign the frequencies to
[L2] .
,
[L2] ,
Go back to access other graphs.
,
[STAT PLOT]
Use the arrows to turn off the remaining plots.
Be sure to deselect or clear all equations before graphing.
Questions & Answers
Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

What is the direction and net electric force on q_{1}= 5µC located at (0,4)r due to charges q_{2}=7mu located at (0,0)m and q_{3}=3\mu C located at (4,0)m?
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

A boat travels due east at a speed of 40meter per seconds across a river flowing due south at 30meter per seconds. what is the resultant speed of the boat
which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
pratica A on solution of hydro chloric acid,B is a solution containing 0.5000 mole ofsodium chlorid per dm³,put A in the burret and titrate 20.00 or 25.00cm³ portion of B using melting orange as the indicator. record the deside of your burret tabulate the burret reading and calculate the average volume of acid used?
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you.
Attracting depends on the mass och each body and distance between them.
Dlovan
Are you really asking if two bodies have to be charged to be influenced by Coulombs Law?
Specific heat capacity is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius (or Kelvin). It is measured in Joules per kilogram per degree Celsius (J/kg°C).
