Question

-Give an example of an experiment from your field of study where a pattern in data is used to construct a mathematical relationship.

-Discuss how plotting data can help you identify the relationship between the current through the resistor and the potential difference across it.

Answer #1

**From Ohm's law **

**the current throw the resistor is proportional to the
potential difference between the ends**

**tha is **

**which is like a equation of a straight line y = mx ,
where m is the slope of the line**

**same way the term R is slope which is
resistance**

**as we increase the potential difference across the ends
the current is also increases , keeping the resistance constant and
temperature conditions also .**

**ploting the graph V vs I ,taking V on y axis and I on x
axis we get the straight line passing through the
origin**

**between any two points we can measure the slope which is
equivalent to the resistance of the resistor**

explain the difference between quantitative and qualitative
data. Give an example of each from the field of criminal justice.
Can both quantitative and qualitative data be used in each of the
four purposes of doing research (list these). Why or Why not?

What are the three types of species dispersion pattern? Give an
example of each.
How do we calculate mortality rate?
Survivorship can be calculated using the following formula:
proportion of individual cohort that survive to age “x”
or (x ÷ by original cohort). The resulting
data can be used to create a survivorship curve. Differentiate
between the three major types (I, II, III).

1. In a testing experiment:
a. What is the difference between a hypothesis and a
prediction?
b. How do you decide if the outcome of the experiment is/is not
consistent with the prediction?
c. How do you make a judgment about the hypothesis? How do the
assumptions you made in your method enter into making this
judgment?
2. In an observational experiment:
a. What is an independent variable?
b. What is the dependent variable?
c. Give an example from your...

How can I use this topic in a study or experiment scenario:
there is a linkage between child abuse and adolescent dating
violence? I did some research, the articles suggest abuse occurring
during childhood can lead to adolescent dating violence in middle
school to high school. Creating either the perpetrator in the
relationship, or the victim. I think I should narrow my study to
child abuse leading to the perpetrator in the adolescent
relationship. Although, how could I set this...

Give an example, USING YOUR OWN WORDS (NOT TEXT COPIED FROM THE
INTERNET), of how either the Poisson or the Exponential
distribution could be used to model something in real life (only
one example is necessary). You can give an example in an area that
interests you (a list of ideas is below). Give a very rough
description of the sample space.
If you use an idea from another source, please provide a citation
in the sentence and a reference...

A) Prove the mathematical relationship between Elastic PE and
extension. Give example
B)Find a relationship between the Elastic PE and the extension.
What happens to the PE as the extension doubles?
You should find a single spring system with a k value
(force/spring constant) of 100N/m
Click on ‘Energy plot’ and ‘Values’. Enter data into the
Displacement box to apply forces. Record the force applied and

Data from drug stability study shows non-linear relationship
between storage time and the concentration of degradation product
in tablets. That relationship is best described by an exponential
equation C=C0*exp(k*t) , where t – storage time (in
months), C and C0 are current (at time t) and initial
concentrations of the degradant, respectively; and k – reaction
constant. We have the data for C, C0 and t for multiple
tablet samples measured every 6 months over 36-months period. Can
we use...

The following data represent the results from an
independent-measures experiment comparing three treatment
conditions with n=4 in each sample. Conduct an analysis of variance

Answer the following questions.
1. Discuss the elements necessary for an effective
offer? Detail each element.
2. What distinguishes a bilateral contract from a unilateral
contract? Give a fact pattern for each.
3. How do capacity and legality play a role in contract law?
Cite an example for each and explain how a court would approach
deciding a case where capacity and a case where legality was at
issue.
4. What are the rules used by Courts regarding the
interpretation of...

How Grounded Is Your Love Life?
In a recent experiment, psychologists at University of
Pittsburgh and the University of Waterloo in Canada decided to
examine stability, turbulence and love. The researchers focused on
stability because it is a term that has both literal and abstract
meanings. Our bodies can be physically stable or they can be
wobbly, and so can our intimate relationships. The study
participants were 40 college students who reported being involved
in a committed relationship that had...
