Scissors * Electrical Wires * Crocodile clips * Micrometer Method: The following procedure described below is how I intend to gain my results: 1. I will measure out the different lengths of copper wire I intend to use using a millimetre ruler to gain the most accurate results I can. 2. Once the lengths are cut‚ the diameter of the copper wire I am using must be measured. To gain the most accurate result‚ I will use a micrometer and measure the

Why is it important to get a brake inspection at the first sign of trouble? If your car starts to emit strange sounds‚ abnormal smells‚ feels different -- start investigating the issue sooner rather than later and risking the condition getting worse. Delaying small repairs often leads to bigger‚ more expensive repair bills down the road. For example‚ when brake pads and shoes stop working‚ the rotors can become warped and damaged‚ and this metal grinding will shorten the life of properly working

equation: where • E is the energy (kilowatt-hours per metric or short ton) • Wi is the work index measured in a laboratory ball mill (kilowatt-hours per metric or short ton) • P80 is the mill circuit product size in micrometers • F80 is the mill circuit feed size in micrometers. Rod mill A rotating drum causes friction and attrition between steel rods and ore particles. But note that the term ’rod mill’ is also used as a synonym for a

cells. Compare by size. Prokaryotic cells are significantly smaller than eukaryotic. In fact‚ eukaryotic cells are typically about ten times larger than prokaryotic cells. The size of cells is usually measured in micrometers‚ with the average prokaryotic cell being around one micrometer wide. 5.diffusion is the transport of solvent from higher concentration to lower concentration. osmosis is the movement of solvent from lower to higher concentration faciliated diffusion is the movement of solvent

LED emission is generally in the visible part of the spectrum (i.e.‚ with wavelengths from 0.4 to 0.7 micrometer) or in the near infrared (with wavelengths between 0.7 and 2.0 micrometers). The brightness of the light observed from an LED depends on the power emitted by the LED and on the relative sensitivity of the eye at the emitted wavelength. Maximum sensitivity occurs at 0.555 micrometer‚ which is in the yellow-orange and green region. The applied voltage in most LEDs is quite low‚ in the region

You will also represent the data using a histogram. Equipment Engineering notebook Pencil Dial caliper Procedure 1. Part of the manufacturing quality control testing for a toy is to measure the depth of a connector piece that must fit into another part. The designed depth is 4.1 cm. Every tenth part produced on the production line is measured. The

Paper Electron diffraction through a graphite film. Mark Raskin Skidmore College (11/14/14) Abstract: In this paper‚ the wave-like properties of electrons are discussed. We are trying to measure the inter-atomic spacing (d) between the graphite atoms‚ which we are accelerating electrons through. As the electrons pass through the graphite‚ an interference pattern emerges on the screen in front of the gun. The interference pattern shows up as a circle within a circle‚ each of which represents

Using the same steps as finding the size of the Paramecium specimen with the ocular reticle and the stage micrometer. Any object can be found by first adjusting the microscope for Kohler illumination and using the 10x objective lens to observe the object. Use the course focus knob and adjust until the object is clear. Afterwards switch the nosepiece into a higher objective and adjust the current magnification with the fine focus knob until the object is in an acceptable field of view. Using the ocular
