True Story! The 1998-1999 Mars Climate Orbiter mission was declared a total loss in1999 as there was a unit conversion mismatch error between Lockheed Martin and NASA. Themismatch was in the thruster force units. NASA used the SI system which called forNewton-Seconds (4.45 times as large) of thrust and Lockheed Martin used Pound-Force Seconds.Calculations placed the Orbiter at 68 miles from the surface as it went into orbit, but it waswithin 57 km of the surface after the breaking maneuver. Any distance from the surface lessthan 50 miles would have caused the Orbiter to crash.a. What was the actual distance of the Orbiter from the surface in miles?b. In percentage, how far off from the calculated 68 miles was the Orbiter?

1. Energy consumption in a country from 2001 to 2011 increased from 1041.3 million to 1526.1 million BOE (barrels of oil equivalent). If the high calorific value (HHV) of the oil is 141,000 kJ/gallon what is the increase in energy consumption over 10 years in Joule units. What is the rate of energy consumption per year? 2. Based on data on the rate of energy consumption per year from question no. 1, if the growth rate energy 2.5% per year, calculate the doubling time (td) and what is the approximate rate of energy growth in 2021.

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
