What are three primary techniques for minimizing exposure to radiation and radioactive materials? (1 point) A. Distance, minimize exposure, and proper Personal Protective Equipment (PPE) B. Prevention, distance, and shielding C. Proper PPE, distance, and proper decontamination D. Time, distance, and shielding 5. The route of entry is how the agent gets into your body.
Answer: Here given, Im = 2.53 mA Dividing Amplitude of voltage Im by √2, 2.53 √2 = 1.8 Comment: Both values were not matching. There have more than 10% discrepancy. Q. 3. Calculate the impedance by the measured values of voltage and current from the oscilloscope.
7. You want to build a circuit which causes a ligh tbulb to turn on when you throw a switch. So, you build the circuit if Figure 5. When the switch is connected to point A the capacitor charges, and when you connect the switch to point B the light goes on. Let the resistance of the light bulb be Rℓ = 1.50 ×103 Ω, the potential difference across the battery is VB = 10.0V , and the capacitor has a capacitance of C = 1.35 × 10−4 F
If 0.65 < r1 < 0.90, then it will take three days to repair the copier. If 0.90 < r1 < 1, then it will take four days to repair the copier. 2. Interval between breakdowns For this type of graphs, the continuous probability function is given by: fx=2xa2 , 0≤x≤a . Here a = 6, So: fx=2x62=2x36=x18 , 0≤x≤6 Therefore, cumulative probability function is
Then you put the remaining liquid (neutral component mixture) through the suction filtration funnel to isolate the crystals. After 10-15 minutes, the crystals will be dry and you can weigh them and find their melting point. How is the neutral component of your 3-compound mixture isolated from the final methylene chloride solution? 16 of 22 4/16/12 9:15 PM StudyBlue Flashcard Printing of Lab Final 2211L UGA http://www.studyblue.com/servlet/printFlashcardDeck?deckId=... Name the four active ingredients that we will be testing for in the TLC of Analgesics lab: Ibuprophen Caffeine Acetaminophen Acetylsalicylic acid What solvent system will you be using to dissolve the common analgesics (power) in preparation for TLC spotting? Methylene chloride: ethanol (1:1 solution) What solvent system will you be using to "develop" your TLC plates in the TLC of Analgesics lab?
The material is stored for ten days at 120 degrees Fahrenheit. Correct 7. Do you consider a 3 percent loss significant? 8. I didn’t have my watch, but I think it was around 1:30.
5) Information about Clearwater Company's direct materials cost follows: Standard price per materials ounce $ 100 Actual quantity used 8,700 grams Standard quantity allowed for production 9,100 grams Price variance $ 76,125 F ________________________________________ Required: What was the actual purchase price per gram? (Round your answer to 2 decimal places. Omit the "$" sign in your response.) Actual purchase price $ 91.25 Total grade: 0.0×1/1 = 0% Feedback: Actual Costs = AP × 8,700 Actual Inputs at Standard Price = $100 × 8,700 =$870,000 Price Variance = $76,125 F 8,700 × AP = $870,000 – $76,125 AP = $91.25 ________________________________________ Question 3: Score
Exothermic and endothermic reactions. First law of thermodynamics and enthalpies of reactions. Calculate standard enthalpies of formations (using the equation on page 191). Electromagnetic radiation, photoelectric effect and continuous and line spectra. Energy levels and electron configurations (including representation using orbital diagrams) of several common elements on the periodic table.
The electrified region of the upper atmosphere which impacts radio communication is called the a. thermosphere. b. mesosphere. c. stratosphere. d. ionosphere. 2.
With the progress in technology applications our exposure with electromagnetic fields, ionizing radiations goes on increasing the threshold limits. From the toxicologic and epidemiologic investigations on static and radiofrequency fields, various aspects of the radiations effects on health have been studied but cancer proved to be most attentive outcome from radiations exposure at high frequencies. These radiations produce significant environmental impacts. Inconsistency in research data and insufficient knowledge causes difficulties in the development of strategies and public health policies. Relevant to this, potential risks to individuals arise due to balancing benefits of technologies to the society.
