A 51−kg person drinks 4.6 × 102 g of milk, which has a caloric value of approximately 3.0 kJ/g. If only 17 percent of the energy in milk is converted to mechanical work, how high (in meters) can the person climb based on this energy intake? Enter your answer in scientific notation.Hint: The work done in ascending is given by mgh, where m is the mass (in kg), g is the gravitational acceleration (9.8 m/s2), and h is the height (in meters).

Eastern loggerhead shrike is a critically endangered species of bird in Canada. Its population has been declining since the 1960s, and it has been speculated that habitat loss, pesticide usage combined, and climate change have affected the shrike population size. In 2004, there were approximately 70 loggerhead shrikes breeding in Canada. Over the next five years, 90 new shrikes were born, 60 died, and 24 left the area. Calculate the change in the population of eastern loggerhead shrike between 2004 and 2009. Express your answer rounded to the nearest whole number.
A beaker of hot water with a volume of 43.9 mL has an initial temperature of 94.3 °C. You place a block of metal that has a mass of 43.89 g into the water until the water and metal are at thermal equilibrium. You record that the temperature of the metal increases by 66.56 °C. What is the final temperature °C at thermal equilibrium of the water and block, assuming no heat is lost to the surroundings? The specific heat of the metal block is 0.237 J/g·°C
A chemical reaction takes place inside a flask submerged in a water bath. The water bath contains 6.90kg of water at 28.0°C. During the reaction 133.kJ of heat flows out of the bath and into the flask. Calculate the new temperature of the water bath. You can assume the specific heat capacity of water under these conditions is 4.18 J·g−1·K−1. Be sure your answer has the correct number of significant digits.
The lowest temperature recorded in a particular city during the past year was −10.73−10.73 ∘∘C. What was the temperature on the kelvin scale?
Measuring the change in temperature versus time upon addition of a hot metal specimen to 10.3 mL of water with an initial temperature of 26.55 degrees Celsius led to a plot with a line with the equation y = -0.121x + 36.55. If the heat absorbed by the water is equal to the heat lost by the metal, determine the specific heat of the metal with a mass of 10.51 g to two decimal places.
