Lab 1. Background
Instructions:
1) Type your answers in this Microsoft Word file and save your completed lab on your computer.
Do not modify the format of the file.
2) Upload your lab on CANVAS by the due date. To upload the file, go to the course homepage and click on “assignments”. Click on the assignment that you want to submit, and on “submit assignment”. In the “file upload” box, click on “choose file” and select the appropriate file. Finally, click on “submit assignment”. Only .doc, .docx, and .pdf files are accepted. 3) In questions that require calculations, you are required to show every step of your work.
4) Proper units and terminology are always necessary. Lab Overview:
While in our American daily lives we use the English system, science (and most of the rest of the
world) use the SI and cgs systems of measurement. Therefore, the main goal of this first lab is for you to familiarize with these systems and to become proficient in converting units from one system to another. The importance of these calculations is critical and goes way beyond this course: you will travel to different countries during your lifetime, and you will for sure become exposed to these systems of measurements. Additional goals for this lab are for you to learn how to write numbers in scientific notation and how to convert from UTC (aka Z (Zulu) or GMT) time to local time. Learning Objectives:
At the end of this lab, you are expected to be able to:
•
Convert from UTC to the local times of the continental US
•
Convert from English to SI and cgs units of measurements and vice versa
•
Apply the rules of the power
•
Rearrange the equation for density to find one variable (e.g., mass) given the other two (e.g., volume and density)
•
Write numbers in scientific notation
1) You took a weather observation in eastern North Dakota on February 15, 2007, at 00 UTC. What was the local standard time and date? (1 point)
Local Time: UTC 6 Date: February 15, 2007
2) With a measuring tape, measure the length and width of your bedroom in ft. Use decimal ft (i.e., don’t use ft and in) and keep two decimal figures. Report the values below. (1 point)
Bedroom length (ft)=10.00ft
Bedroom width (ft)=10.00ft
3) Convert into in and report the values below (1 ft=12 in). Keep two decimal figures. (1 point)
Bedroom length (in)=120.00in
Bedroom width (in)=120.00in
4) Convert into m and report the values below (1 m=3.28 ft). Keep two decimal figures. (1 point)
Bedroom length (m)=3.05m
Bedroom width (m)=3.05m
5) Calculate the area of your bedroom in ft
2
and report the value below. Keep two decimal figures. (1 point)
Bedroom area (ft
2
)=100.00ft^2
6) Convert into in
2
and report the value below (1 ft=12 in). Keep two decimal figures. (1 point)
Bedroom area (in
2
)=14400.00in^2
7) Convert into m
2
and report the value below (1 m=3.28 ft). Keep two decimal figures in the final result and in your intermediate calculations. (1 point)
Bedroom area (m
2
)=9.29m^2
8) Measure the height of your room in ft and report the value below. Use decimal feet and keep two decimal figures. (1 point)
Bedroom height (ft)=7.83ft
9) Measure the volume of your bedroom in ft
3
and report the value below. Keep two decimal figures. (1 point)
Bedroom volume (ft
3
)=783.00ft^3
10) Convert into m
3
and report the value below (1 m=3.28 ft). Keep two decimal figures in the final result and in all your intermediate calculations. (1 point)
Bedroom volume (m
3
=22.21^3
11) Your bedroom is filled with air. Air density depends on elevation, temperature, and humidity. Assuming the air in your bedroom has a density of 1.23 kg x m
-3
, calculate the mass of air that is filling your room in kg and report the value below. Keep two decimal figures. (1 point)
Mass of air in the bedroom (kg)=27.32
12) Convert into lb and report the value below (1 kg=2.2 lb). Keep two decimal figures. (1 point)
Mass of air in the bedroom (lb)=12.42
13) An average breath of fresh air contains 10
22
molecules. The entire atmosphere contains 10
44 molecules. Calculate the number of breaths of air that are in the entire atmosphere and report the value below. (1 point)
Number of breaths of air in the atmosphere=10^22
14) Go to the following website https://forecast.weather.gov/MapClick.php?lat=40.2337 HYPERLINK "https://forecast.weather.gov/MapClick.php?lat=40.2337&lon=-111.6685"& HYPERLINK "https://forecast.weather.gov/MapClick.php?lat=40.2337&lon=-111.6685"lon=-

. Report the value for the current wind speed at the Provo Airport in mi/hr. (1 point)
Wind speed (mi/hr)=0
15) Convert into km/hr and report the value below (1 mi=1.61 km). If the wind speed was 0 mi/hr, use a value of 17 mi/hr. Keep two decimal figures. (1 point)
Wind speed (km/hr)=0

16) Convert into m/sec and report the value below (1 km=1,000 m). Keep two decimal figures. (1 point)
Wind speed (m/sec)=0
17) A unit of distance traditionally used is the nautical mile, which is equal to one minute of latitude or to 1.15 statute (i.e., regular) miles. When distances are measured in nautical miles, speeds are measured in knots, where one knot is equal to one nautical mile per hour. Convert the current wind speed at the Provo Airport into knots. Keep two decimal figures. (1 point)
Wind speed (knots)=0
