1)Energy Efficiency at Home: Suppose you have two kettles – a plug-in electric kettle and a stovetop kettle. The electric kettle uses electricity from a natural gas-fired powerplant, while you boil water in your stovetop kettle on a natural gas burner.
a)Based on the following information, which of these kettles demonstrates a higher energy efficiency (i.e., which is more efficient at using energy from fuel to heat water)? Please calculate the efficiencies of each kettle and express answers as percentages.
-The natural gas power plant converts the chemical energy of the natural gas to electrical energy with 58% efficiency.
-High-voltage power lines from the power plant to your house convey electricity with 92% efficiency.
-The electric kettle converts electrical energy to thermal energy in the water with 85% efficiency (the other 15% heats up the kettle itself).
-The stove burner…
For this question, CHOOSE THE CORRECT ANSWER, then explain your reasoning in the RATIONALE section below: Alpha,
Beta-plus, Beta-minus and Gamma decay are all different forms of radio-Active decay. A certain radio-isotope emits ONE
alpha particle, and its products then emit TWO beta-minus particles in succession. The atomic number of the final resulting
nucleus will now change (as compared to your starting nucleus) by
O A. zero
O B. minus 1
OC. minus 2
O D. minus 3

The method has proven invaluable for providing calendar dates for a range of different materials and many different time periods. Radiocarbon dating, however, is not without its limitations and uncertainties, so it is important for archaeologists to be aware of a range of issues when using the technique. For the second part of this assignment, please answer the questions below. 6. List two kinds of archaeological materials can be dated using the radiocarbon method and two that cannot be dated with radiocarbon. 7. In one or two sentences, explain why radiocarbon ages need to be calibrated into calendrical ages? 8. A radiocarbon date on wood charcoal was obtained from Layer N in the stratigraphic profile above. The date has a radiocarbon age of 5500 BP ± 50 yrs and it calibrates to 4450-4260 cal. BC. Burial W in Layer E was also dated and has a radiocarbon age of 5000 BP ± 30, which…arrow_forward
