Problem 1a: Velocity Selector: Show that with the right ratio of electric to magnetic field strength a particle of velocity v will proceed through both fields in a straight line at constant speed (hint: you will need an equation containing v. Also: what does the straight line at constant speed give you?). Assume that the angle of the velocity vector relative to the magnetic field vector is 90 degrees.

b: Show mathematically that the charge magnitude and sign do not matter.

c: Draw and label the electric field vector, the electric force vector, the magnetic field vector, the velocity vector and the magnetic force vector. Hint: start with the two force vectors. They have to add to zero. Then use the vector nature of the Eq = F(E) equation and the right hand rule to get the other vectors.) Assume that the particle is negatively charged. Use into and out of the page vector notation where necessary.

d. Explain in terms of what happens with the force vectors when the charge sign changes to allow a particle of either charge sign pass through the velocity selector at constant velocity v. In other words, explain physically why the particle charge sign makes no difference.

e. Explain in terms of what happens with the force vectors when the charge magnitude changes. In other words, explain physically why the charge magnitude makes no difference in the velocity selector.

n Jacobson v. Massachusetts (1905), the United States Supreme Court upheld the right of states to enact compulsory vaccination laws—one of the most challenging constitutional dimensions of public health. It also provided the terms for what would eventually become a core question of public health ethics.

This case has become the precedent for many cases that have challenged vaccination laws. Both majority and dissenting opinions in numerous decisions have cited this case in reference to states’ authority to constrain individual behavior. These cases have involved issues ranging from fluoridation of municipal water supplies, to abortion, to the right to die. In Buck v. Bell (1927), the Supreme Court usedJacobson v. Massachusetts (1905) to uphold a forced-sterilization law using the reasoning that society must be protected from the burdens imposed by the offspring of “imbeciles.” Despite the troubling uses to which this decision has been put, public health law texts continue to cite the case as an example of the ways that public health practices must resolve the tensions between individual rights and the collective well-being.

Based on these Supreme Court decisions, respond to the following:

• Do you believe health departments should be able to enter your house without a warrant from a judge?
• Should health departments be able to isolate or quarantine you without a trial? Why or why not?

A rigid tank with volume Vtank=20 liter is maintained at T1=300 C and initially contain m1=0.08 kg of water as shown in the figure. At some time, a valve is opened allowing Vin=2 liters of waters at Tin=20 C and Pin=20.0 MPa to enter the tank. The valve is shut and eventually all of the water in the tank comes to T2=300 C.

a)Locate state 1 and state in, the states of the water initially in the tank and the water added to the tank, respectively, on a sketch of a T-v diagram. Indicate on your diagram what two properties define each state as well as lines of constant pressures (isobars), lines of constant specific volume (isochors) and/or lines of constant temperatures (isotherms)).

b)What is the initial pressure in the tank (MPa)?

c)What is the mass of the water added to the tank (kg)?

d)Locate state 2, the final state of the water in the tank, on the T-v diagram from (a).

e) What is the final pressure in the tank (MPa)?

f) Explain how it is possible for the temperature of the water in the tank to remain constant at 3000C after adding water with much lower temperature ( 20oC ) to the tank.

g)On a P-v diagram overlay initial state and final state of water in the tank. Indicate on your diagram what two properties define each states and draw isotherms.

IV              Suppose the U.S. government began 2016 with no debt. The expenditures listed below do not include interest on debt.

                  2016: Spending on goods & services and transfers         $4.5 trillion

                              tax receipts                                                                                      $4 trillion

                  What is the budget deficit? How much must the Treasury borrow?

                  2017:   Expenditures and tax receipts both increase by 1% from the year before.

                               In addition, the debt incurred in 2016 has a 2% interest rate, which must be paid this year.

                  What is the budget deficit? How much must the Treasury borrow? What is its total debt?

                  2018:   Spending and tax are same as 2017. Bonds issued in 2017 carry the same interest rate.

                  What is the budget deficit? How much must the Treasury borrow? What is its total debt?

                  2019:   Spending is the same as 2018. But taxes increase 10% due to major expansion in macroeconomy. Bonds issued in 2018 carry the same interest rate. In addition, half of the                                         (cumulative) Treasury bonds mature this year.

                  What is the budget deficit? How much must the Treasury borrow? How much in bonds must it issue?

On January 1, 2016, Ballieu Company leases specialty equipment with an economic life of 8 years to Anderson Company. The lease contains the following terms and provisions:

The lessor calculates that the present value on January 1, 2016 of 8 annual payments in advance of $40,500 discounted at 13% is $219,615.71 (the $1 purchase option is ignored as immaterial).

Skysong Company began operations on January 1, 2016, adopting the conventional retail inventory system. None of the company’s merchandise was marked down in 2016 and, because there was no beginning inventory, its ending inventory for 2016 of $37,300 would have been the same under either the conventional retail system or the LIFO retail system.

On December 31, 2017, the store management considers adopting the LIFO retail system and desires to know how the December 31, 2017, inventory would appear under both systems. All pertinent data regarding purchases, sales, markups, and markdowns are shown below. There has been no change in the price level.

Determine the cost of the 2017 ending inventory under both (a) the conventional retail method and (b) the LIFO retail method. (Round ratios for computational purposes to 2 decimal place, e.g. 78.72% and final answers to 0 decimal places, e.g. 28,987.)

I got A, just need B. The answer to B isnt 48905

Some social scientists have collected data on smartphone ownership among teenagers. In 2016, 84% of 12-17 year olds sampled owned at least one smartphone. In 2018, that number increased to 92%. For the purpose of this problem, you can assume that these values were from independent samples of 12-17 year olds taken in 2016 and 2018, each of size 120. We will test the null hypothesis that the population percentage of teenagers owning at least one smartphone was the same between 2016 and 2018, versus the alternative hypothesis that these percentages were different.

(a) Under the null hypothesis, the difference in the sample percentages is expected to be ___________%. The standard error for the difference is estimated to be ___________%.

(b) The appropriate test statistic to use is (circle one) one-sample z-test two-sample z-test one-sample t-test chi-squared test for proportions chi-squared test of independence none of these

(c) The value of the test statistic is _________________.

(d) The p-value is _________________________. (Give a percentage for a z-test or a range of percentages for a t-test or chi-squared test.)

(e) Our conclusion is (circle one) reject the null hypothesis OR don't reject the null hypothesis.
