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?

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
