What are the differences between a test charge and a point charge?
Aru4real
A point charge is an electric charge that is concentrated at one mathematical point with no spacial extent, A test charge is a charge that is small enough to have no effect on a system, but is used to study a property.

When probing the electric field direction it is necessary to specify that the magnitude of the test charge be very small?
A large "test charge" would influence the field you want to measure.
Hopkin's cole test reaction?
Produces a Purple ring at the point of contact of the two liquids. :)
Three test tubes labeled A B and C contain substances with appromimately the same melting points. How could you prove the test tubes contain three different chemical compounds?
You can label the test tubes with the names or letters like A,B and C. The difference can be seen from looking at the test tubes. However; there are also tests that can help you differentiate between different substance.
Does the dealer pay for smog test?
The dealer has the option to pay for the smog test or to have you pay for it. They are allowed to charge you what it costs them to get it smogged plus $50. If the dealer is paying for the smog test themselves you can expect to have the smogging cost included in the selling price. See reference: http://www.webcarsandtrucks.com/faq.html#who%20pays
What is the difference between iodine solution and Benedict's solution?
Benedict's solution is used to test for simple sugars and iodine is used to test for starches.
What can you determine from an electric field vector at one point?
From an electric field vector at one point, you can determine the direction of the electrostatic force on a test charge of known sign at that point. You can also determine the magnitude of the electrostatic force exerted per unit charge on a test charge at that point.
What is Breslow-Gehan-Wilcoxon Test to compare kaplan curves?
This test evaluates differences between study groups, it allows weighting of time points by the number of cases at risk at each time point
What is electric entensity?
the force experienced by a test charge q placed at that point
Why should an test charge be of negligibly smaller magnitude?
The magnitude of the test charge must be small enough so that it does not disturb the distribution of the charges whose electric field we wish to measure otherwise the measured field will be different from the actual field.
What's the similarties and differences between multiple choice test and essay test?
a multiple choice gives you the chance to guess
What are the differences in test scores between normal schools and year round schools?
nothing.
When determining an electric field must a positive test charge be used or would a negative one do as well?
We could just as well use a negative test charge to determine an electric field, but then the Electric field vector would point opposite the direction of the force on the test charge.
Differences between index and direct test?
The indirect test is one that you might find out about while researching. The direct testis what you are looking for.

What is the difference between control samples and test experimental samples?
It calculates the difference between each set of pairs, and analyzes that list of differences. The P value answersthis question: If the median difference in the ... If your samples are small and there are no tied ranks, Prism calculates an ... The whole point of using a paired test is to control for experimental.
What are the differences between a two sample t-test and ANOVA hypothesis testing?
In ANOVA, what does F=1 mean? What are the differences between a two sample t-test and ANOVA hypothesis testing? When would you use ANOVA at your place of employment, in your education, or in politics?
What happens to the size of the electric filed if the charge on the test charge is halved?
Test charge is always a test charge. The electric field does not depend on the test charge. Usually we assume the test charge to be one coulomb positive charge. Though you make it half, it would never affect the field around the primary charge
