Can you imagine living in the young America we are reading about? If you could visit the U.S. in this era (say, you would have to stay for one hundred days, but then you could come back to the present) would you do so? Why/why not? Time travel may not be possible, but "human wormholes" certainly are, and they can reveal just how near to us "history" remains.

A farsighted woman breaks her current eyeglasses and is using an old pair whose refractive power is 1.785 diopters. Since these eyeglasses do not completely correct her vision, she must hold a newspaper 42.00 cm from her eyes in order to read it. She wears the eyeglasses 2.00 cm from her eyes. How far is her near point from her eyes?

A chemist analyzes seawater samples for two heavy metals: lead and mercury. Past experience indicates that 38% of the samples taken from near the mouth of a river on which numerous industrial plants are located contain toxic levels of lead or mercury; 32% contain toxic levels of lead and 16% contain toxic levels of mercury

What is the probability that a randomly selected sample will not contain lead or will not contain mercury?

Assignment Task Two (300 words - 7 marks)

The coronavirus intervened Australia in early 2020.

On 12 May, the Morrison government issued an unprecedented progress report on the delayed budget, outlining the coronavirus pounding to the national economy and the huge outlay to deal with the pandemic.

What were the main issues presented? How do you think they would affect the economy, social and employment situation in the near future?

Bifocal glasses are used to correct both nearsightedness and farsightedness at the same time. (Figure 1)

Part A: If the near points in the right and left eyes are 38.0 cm and 46.0 cm , respectively, and the far point is 210 cm for both eyes, what are the powers of the lens prescribed for the right eye? (Assume that the glasses are worn 3.00 cm from the eyes.)

Part B: What are the powers of the lens prescribed for the left eye?

As a response to the economic slowdown following the financial crisis, the Fed cut the Federal funds rate to near 0 by the end of 2008, and tried to provide further monetary stimulus through “unconventional” policies. In a short paragraph, describe some of these unconventional tools that were used by the Fed during this period, and explain how these tools could increase demand even when the Fed funds rate stays constant at zero.

Please create a PESTEL analysis for Kirkland's, Inc. Home Decor. Answer How, for instance, is the current political environment of your organization affecting it? (Consider everything from local to national politics!) How may various changes in the political environment in the future (both the near future and further out) affect it? Repeat and answer these two questions for the economy, society and culture, technology, natural environment, and the legal and regulatory milieu.

Draw something interesting with JavaFX. The drawing must be something coherent - random shapes on the canvas will not receive near full marks. Your drawing must make use of at least the following:

1) a compound object generated by a for loop

2) each of a rectangle, arc, circle, ellipse, line,

3) at least 15 shapes overall

4) 5 different colours

5) the use of translation, rotation, and scaling

CASE STUDY 6.1 IMPORTANT CONSIDERATIONS FOR AN UNDERAGE DRINKING INTERVENTION

Dr. Smith works for a local university, and has been approached by a local health department about a project pertaining to high alcohol consumption among high school students. According to local statistics produced by the health department, 35% of adolescents in the community have never had alcohol and do not plan to have it in the near future, 35% of adolescents have never had alcohol but are planning to try it or are willing to try it in the near future, 25% of adolescents have consumed alcohol at least once in the last 30 days, and 5% of adolescents have consumed alcohol at least 5 times in the last 30 days. The local health department wants to create an intervention to reduce underage drinking in the community but is unsure about what to target, whom to target, and how to implement the program.

Questions for Reflection and Discussion

1. In a comprehensive intervention, which levels of prevention would be relevant?

2. How could the ecological model be used to help identify factors associated with underage drinking? Brainstorm various factors in the ecological model that could be associated with underage drinking.

Exhibit 20-1

You have two metal spheres on insulating stands. You bring them each in turn near the ball of a positively charged electroscope. In each case the deflction of the leaves is reduced slightly. You then bring them each in turn near the ball of a negatively charged electroscope and find that sphere A causes the deflection to increase, whereas sphere B causes it to decrease.

7.Refer to Exhibit 20-1. Sphere A is

a. positively charged.

b. negatively charged.

c. neutral.

d. There is not enough information to determine this.

8.Refer to Exhibit 20-1. Sphere B is

a. positively charged.

b. negatively charged.

c. neutral.

d. There is not enough information to determine this.

9.A metal sphere on an insulating stand has a charge of 16 nC. A second metal sphere, also on an insulating stand, is initially uncharged. The two spheres are briefly touched together. The second sphere is then grounded. After this procedure, the charge on the original sphere is

a. 16 nC

b. 8 nC

c. 4 nC

d. 0 nC

e. more than 16 nC

f. There is not enough information to determine this
