After years of rapid growth, illegal immigration into the United States has declined, perhaps owing to the recession and increased border enforcement by the United States (Los Angeles Times, September 1, 2010). While its share has declined, California still accounts for 35% of the nation’s estimated 11.3 million undocumented immigrants.

a. In a sample of 60 illegal immigrants, what is the probability that more than 21% live in California? (Round “z” value to 2 decimal places, and final answer to 4 decimal places.)

b. In a sample of 120 illegal immigrants, what is the probability that more than 21% live in California? (Round “z” value to 2 decimal places, and final answer to 4 decimal places.)

c. Comment on the reason for the difference between the computed probabilities in parts a and b.

• As the sample number increases, the probability of more than 21% also increases, due to the lower z value and decreased standard error.

• As the sample number increases, the probability of more than 21% also increases, due to the lower z value and increased standard error.

ANSWER THESE QUESTIONS USING TRUE OR FALSE:

a. Gauss’s Law describes the relationship between the net electric flux through a closed surface and the charge enclosed INSIDE the surface.

b. Gauss’s Law describes the relationship between the net electric flux through any surface (either open or closed) and the charge around (either inside or outside) the surface.

c. When a point charge is at the center of a spherical surface, its E field is EVERYWHERE normal to the surface and constant in magnitude.

d. When a point charge is inside some closed Gaussian surfaces, the total net E field flux depends on the shape and size of the surfaces.

e. When charges are only located OUTSIDE an enclosed Gaussian surface, the number of E field lines entering the surface may be more or less than that of the lines leaving the surface.

f. Chapter 24-2 derived the formula of Gauss’s law using a positive point charge located inside a cubic Gaussian surface.

g. Dr. Gauss made contributions on many fields and a picture of him was shown in chapter 24.2

h. Gauss’s law is not true when there are multiple charges.

i. Zero flux means zero electric field.

j. There is zero flux through a closed surface when there are no charge inside or when there are charges inside but the net charge is zero (Same amount of positive and negative charges).

k. Gauss’s law calculation uses the value of charges inside the Gaussian surface, but it finds the Total E field at the surface, due to both charges inside and outside of the surface.

l. If the point charge inside the Gaussian surface is tripled, the total flux through the surface must be tripled.

m. If the radius of a spherical Gaussian surface is doubled when a point charge is inside, the total flux through the surface is doubled.

n. If the point charge inside the Gaussian surface moves to a different location, the total flux through the surface is not changed.

In outer space rock 1, with mass 3 kg and velocity < 3500, -2500, 3200 > m/s, struck rock 2, which was at rest. After the collision, rock 1's velocity is < 3000, -1800, 3500 > m/s. What is the final momentum of rock 2?
_2f =  

kg · m/s
Before the collision, what was the kinetic energy of rock 1?
K_1i =  J
Before the collision, what was the kinetic energy of rock 2?
K_2i =  J
After the collision, what is the kinetic energy of rock 1?
K_1f =  J
Suppose the collision was elastic (that is, no change in kinetic energy and therefore no change in thermal or other internal energy of the rocks). In that case, after the collision, what is the kinetic energy of rock 2?
K_2f =  J
On the other hand, suppose that in the collision some of the kinetic energy is converted into thermal energy of the two rocks, where E_thermal,1 + E_thermal,2 = 4.46 ⨯ 10⁶ J. What is the final kinetic energy of rock 2?
K_2f =  J
In this case (some of the kinetic energy being converted to thermal energy), what was the transfer of energy Q (microscopic work) from the surroundings into the two-rock system during the collision? (Remember that Q represents energy transfer due to a temperature difference between a system and its surroundings.)
Q =  J

An SAT prep course claims to improve the test score of students. The table below shows the scores for seven students the first two times they took the verbal SAT. Before taking the SAT for the second time, each student took a course to try to improve his or her verbal SAT scores. Do these results support the claim that the SAT prep course improves the students' verbal SAT scores?

Let d=(verbal SAT scores prior to taking the prep course)−(verbal SAT scores after taking the prep course)d=(verbal SAT scores prior to taking the prep course)−(verbal SAT scores after taking the prep course). Use a significance level of α=0.01α=0.01 for the test. Assume that the verbal SAT scores are normally distributed for the population of students both before and after taking the SAT prep course.
