Measure the diameter and circumference of 5 circles using cylinders of different sizes. Use a ruler measure the diameter of a cylinder in mm (use precision and sig fig)
Take a strip of paper (or string) to wrap around the cylinder and mark the length.
Measure the length of the strip in mm to the tenths place!!
Enter this data on the Table I below
Repeat steps one through 4 for the remaining circle

make a chart:
Cylinder diameter circumference
1 l l
2 l l
3 l l
4 l l
5 l l

Once you have accumulated your data;
Create a scatterplot using Google Sheets
Make sure your graph has axis labels, units and titles.
Include the trendline (line of best fit)
Show the equation of the line for the scatter plot in y=mx+b

What is the equation of the line?
What is the slope of this line?

What does the slope of the line represent?

Calculate the percent error (what was the actual value?)

What do you think are the sources of error in this experiment?

The plum pudding model of the atom state that ?

The particle in a two-dimensional well is a useful model for the motion of electrons around the indole ring (3), the conjugated cycle found in the side chain of tryptophan. we may regard indole as a rectangle with sides of length 280 pm and 450 pm, with 10 electrons in the conjugated p system. as in case study 9.1, we assume that in the ground state of the molecule each quantized level is occupied by two electrons. (a) calculate the energy of an electron in the highest occupied level. (b) calculate the frequency of radiation that can induce a transition between the highest occupied and lowest unoccupied levels. 9.27 electrons around the porphine ring (4), the conjugated macrocycle that forms the structural basis of the heme group and the chlorophylls. we may treat the group as a circular ring of radius 440 pm, with 20 electrons in the conjugated system moving along the perimeter of the ring. as in exercise 9.26, assume that in the ground state of the molecule quantized each level is occupied by two electrons. (a) calculate the energy and angular momentum of an electron in the highest occupied level. (b) calculate the frequency of radiation that can induce a transition between the highest occupied and lowest unoccupied levels.

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.
