EXTENDED DATE: SEPTEMBER 15, 2014.
Here is the next checkpoint everyone! Everyone can work on these questions together - and points will be distributed out!
This blog post will be removed after the checkpoint is completed on September 10th. But you must SHOW YOUR WORK to get full credit.
1a) Convert 0.016 MW to nW. Please express your answer in scientific notation.
1b) How many ergs are in one microjoule?
2. Three teaspoons are a tablespoon. Two tablespoons are one fluid ounce (a fluid ounce is a unit of volume, not weight), and eight fluid ounces is a cup. There are two cups in a pint, two pints in a quart, and four quarts in a gallon. There are 3.785 liters in a gallon, so a liter is just a little bit bigger than a quart. This all happens to be pretty convenient to memorize for cooking!
2a) You are imprisoned by an angry wizard, who gives you a teaspoon and demands that you use it to empty the Pacific Ocean into a bottomless pit. The Pacific Ocean has a volume of about 6.5 X 108 km3. Express this volume in teaspoons in scientific notation.
2b) Magically, you seem to have no need for food or sleep. If you can average one teaspoon every two seconds and work unceasingly, how many years will it take you? Ignore realistic issues like rainfall or the fact that other oceans would drain into the Pacific Ocean once it was partially emptied.
3a) Describe the resultant vector in part 2a. By describing, I mean by labeling components, or magnitude with direction.
3b) Describe the resultant vector in part 2b. By describing, I mean by labeling components, or magnitude with direction.
4. A eukaryotic cell is approximately a sphere with diameter 20 microns. What is its volume in Å3, expressing your answer in scientific notation?
5. Define vector A as <45,468,132>. Define vector B as <-456,-975,-33>. Define vector C as <-43,-467,-136>. Define vector D as <-453,-977,-38>. Vector E is pointing into the computer screen 4 centimeters long. What is the angle in degrees between the vectors A+C and B – D?
6. For every user, type the first number that pops into your head when you see this question.
7. Spoonstinkle is a very fast runner whose fastest 1-mile time is 4:30 (actually, did you know that 3primetime3 knows a friend that runs a mile faster?). Today, he begins a weekend workout in preparation for the marathon coming up in about six months. Starting from Forkstickle High School, he runs 2.6 miles east to the nearest park, known as Knifestirkle. This took him 13 minutes. Instead of running at the park, Spoonstinkle decides to turn left and run another 7 miles to his favorite restaurant, named Napkinstilts. It took him 32 minutes to run to the restaurant from the park and exactly an hour to eat/digest (because running is not good with a full stomach). Because he became lazy, he decided not to go further and took a straight 7.46 mile diagonal from the restaurant back to Forkstickle High where he started is This took him 47 minutes to run. What is his displacement?
