Document Summary

Activity sheet #1: research methods are specific procedures for collecting and analyzing data. Developing your research methods is an integral part of your research design. When planning your methods, there are two key decisions you will make. No matter how many experiences you have or how diverse your social circle, there are things you do not know. Research unlocks the unknowns, lets you explore the world from different perspectives, and fuels a deeper understanding. In some areas, research is an essential part of success. In others, it may not be necessary, but it has many benefits. Here are ten reasons why research is important: The most obvious reason to do research is that you will learn more. There is always more to learn about a topic, even if you are already well versed in it. If you are not, research allows you to build on any personal experience you have with the subject.

You are to design a procedure to determine experimentally thespecific heat of an unknown liquid. You may not damage or destroyany equipment you use, and your method must be feasible andpractical.
a. List the equipment you would need. Include a labeleddiagram.
b. Describe the measurements you would make. Assign eachmeasurement a symbol.
c. Show explicitly using equations how the measured quantitieswould be used to determine the specific heat of the unknownliquid.
d. Indicate one possible source of experimental error and discusshow it would affect your value for the specific heat. Justify youranswer.

I am so lost onwere to even begin. I just need help trying to find the Ѳ (angle)for part part 1 of the experiment if anyone can just explain how todo that and maybe give me a step-by-step example so I can finishthe rest. Thank you! Experiment 6 ~ Friction

Purpose:

In this lab, you will make some basic measurements of friction.You will measure the coefficients of staticfriction between several combinations of surfaces using aninclined plane, and you will measure the coefficient ofkinetic friction between two of the combinationsof surfaces you used in the static friction part of thisexperiment.

Part 1: StaticFriction

Theory:

The coefficient of static frictionms can be measured experimentally foran object placed on an inclined plane (a.k.a. ramp, a.k.a. hill).The coefficient of static friction is related to the criticalangle qc for the ramp, at whichthe object just begins to slide. Using what we havecovered in class, you can derive this relationshipyourself! At this critical angle, static friction preventing theobject from sliding down the hill is just exactly equal to thecomponent of the object’s weight along the hill. If the componentof the weight along the hill were just a little greater, it wouldovercome friction, and the object would start to slide down. Thefree body diagram for this situation will look like the figuresketched below. Use this diagram to find an equation that relatesms toqc.

Questions:

1. How do the values of ms compareto the values of mk? (Of course, youcan only compare them for the same pairs of materials.)

2. Is the relationship betweenmsand mkwhat you expected?

3. Of the two parts of the experiment, measurement ofmsand measurement ofmk, which had more sources of error?What were some of the sources of error?

4. Could mk orms ever be greater than 1? Explain whyor why not.

5. Is the coefficient of friction the same as when the block wasstanding on its larger (or smaller) end?

6. Think about your results. Do they make sense when youconsider your everyday experiences?

Describe qualitatively but specifically how the circuit quantities change after the switch is closed in the circuit a) current b) voltage across the capacitor. Explain why these quantities change as they do, in terms of motion and presence of the capacitor.
 
Imagine repeating the timin experiments you can in this lab, only this time starting with a partially-charged capacitor. Describe how the timings differ from above, explaining how this difference originated from specific electrical quantities in the circuit (e.g. charge, voltage, etc. )
