Question is attached. How do we find the distance between the slits?
2. Light consisting of two different wavelengths, 500 nmand 700 nm, is incident on two slits. On a screen which is1.0 m from the slits the distance between the first ordermaxima produced by the two different wavelengths is 2.0 mm. Find the distance between the slits,
Light Bright believes it can sell 40,000 of its newly developed laser lights at a price of $24.00 each. There will be $600,000 in fixed costs associated with the laser light. If the company desires to make a profit of $100,000 on the laser light, what is the target variable cost for each laser light?
Light attenuation: Using the Beer-Lambert Law:
a) Plot (Ix/Io), versus path length in centimeters, for a 1.0 x 10-3 M solution of an absorber in a 10-cm long cell, with a molar absorptivity of (i) ε = 1.0 x 101 L cm-1 mol-1 , (ii) ε = 1.0 x 102 L cm-1 mol-1 and(iii) ε = 1.0 x 103 L cm-1 mol-1 . (5 marks)
b) In each case also calculate the path length at which the irradiation intensity would have dropped to 50% of its initial value. Use this result to illustrate why rapid stirring is desirable in photochemical reactions involving highly absorbing solutions. (5 marks) Hint: Use a spreadsheet, solving for (I/Io) at 100 evenly-spaced lengths along the path of the beam in steps of 0.1 cm.
Lifespan and Development: Making Tough Decisions Paper
Required Resources
InstructionsFor this assignment, you will compare/contrast a controversial topic in lifespan development – the immunization controversy in the medical profession. Be certain that your answers are cogent, well-formed, and supported by outside research rather than based on personal opinion.
Write about the immunization controversy in the medical profession. Be sure to address why people delay immunizations and why some refuse all immunizations for their children. As a medical professional, how might you educate these caregivers about their child’s health and development concerning this issue? What is your role in this process/situation? How can you best respect the caregiver’s wishes and provide the best healthcare in this situation?

1. Life Style Surveillance
Digitization, technology and applications permit us to monitor our physical activity and health statistics. Employers are increasingly interested in influencing or controlling the non-work activities of their employees. Describe the potential benefits to be gained from employers’ collecting/using employee lifestyle data. For example, do employees exercise regularly? Do they smoke? Document one example of an employer collecting or accessing information about employee non-duty activities. Identify and explain legal and ethical challenges to the practice of monitoring employee off- duty lifestyle activities.
LIFE STAGES NUTRITION PRESENTATION
Create a 15- to 20-slide Microsoft® PowerPoint® presentation discussing the nutritional needs during a person’s different life stages (childhood, adulthood, pregnancy, lactation, and such). Include the following in your presentation:
Define nutrient, energy, and fluid needs during each life stage.
Describe nutrients of concern or special concerns during each life stage.
Identify physical activity recommendations during each life stage.
Discuss the following topics for the specified stages of life:
Pregnancy – weight gain recommendations
Lactation – benefits of breastfeeding
Infancy – growth rate
Childhood – helping kids develop healthy eating habits and bodies
Adolescence – helping teens meet nutrient needs
Adulthood – aging and factors that affect it
Include introductory slide, conclusion slide and reference slide
Include speaker notes that detail the implications of each slide.
Include a reference slide with citations in APA format.
Include clip art.
PART 2 FOOD SAFETY
Consult the Food Safety Scenarios document and then complete the following for each scenario:

#7. Lime Finance Company requires its customers to purchase a credit life insurance policy associated with the loans it makes. Lime is the beneficiary of the policy to the extent of the remaining balance on the loan at the time of the customer’s death. In 2010, Lime wrote off as uncollectible a $5,000 account receivable from Wally, which included $1,500 of accrued interest. When Wally died in 2011, the life insurance policy was still in force, and Lime received $3,500. Is the $3,500 of life insurance proceeds received by Lime included in its gross income?
