	F.	Newton Meter/Second
	G.	Watts
	H. 3. Consider the man from question number 1. What is his power consumption in Watts? 4. Using the information from number 1 again. How much work was done by the man in climbing up the mountain? 5. Using the information in number 1, what was the power output of the man climbing up the mountain? 6. Using the information you gathered earlier, what is the percent efficiency of the man in climbing up the mountain based on his power consumption and the power output? 7. What is the temperature in degrees Celsius of a person with a fever of 104 degrees Fahrenheit? 8. The Golden gate bridge has an overall length of approximately 3000meters. If the bridge experiences temperature extrememes from -10 to 44 degrees Celsius, what will be the change in length? Assume that the bridge is primarily made of steel.	Watts/second
