Why do you think this is?arrow_forwardWrite the scientific notation (10n) 0012 = 560000 = Write out the number 3 x 104 = 8 x 10-2 = How many centimeters are in 2 kilometers?

No, that's not the correct answer. O 2. running at 4 min per mile. Enter to 2 significant figures Angle with respect to the vertical = 6.8 Use 1 mile = 1609.4 m Sense-making: Do your results for the leaning angle during walking agree with your observations about people walking on circular tracks?

- Rewrite the following expression in proper scientific notation as in the example at page 1. Note that here you also have to take care of the number of significant digits. (1.4088x102) (1.8775x101) (6.0110x104) (7.76)/ (2.4x10-4) (4.01x1010) (8.80x101) 3) Solve the above expression using your calculator. Round your answer to the appropriate number of significant digits. (need this)arrow_forwardMap scales may be presented as a ratio, or as a bar on which distances are measured. A ratio of 1:50,000 means that every inch on the map represents 50,000 inches on the ground. If a has a scale where 1 inch represents 1 mile, what would be the scale expressed as a map ratio? (Hint: you need to calculate how many inches are in a mile) 1: On the bar below, how many miles are represented by 1 inch? miles What is this scale expressed as a ratio? 1: What is the value of point 'X'? 10 X 20 Scale (miles)arrow_forwardExplain this statement and give example. Sometimes common sense is enough to enable one to decide whether the results of the mathematics are appropriate. (For example, to estimate the height 20 years from now of a girl who is 5' 5" tall and growing at the rate of an inch per year, common sense suggests rejecting the simple "rate times time" answer of 7' 1" as highly unlikely.)arrow_forward
- which is greater 10 centimeters or 103 millmeters? How much greater?arrow_forwardOxygen Atoms in People. Figure 5.7 shows that oxygen makes up about 65% of the mass of a human being. A single oxygen atom has a mass of 2.66 × 10−26 kg. (a) Use this fact to estimate the number of oxygen atoms in your body. (Hint: If you know your weight in pounds, you can convert to kilograms by dividing by 2.2.) (b) Compare your answer to the number of stars in the observable universe (which is roughly 1022).arrow_forwardThe Earth is travelling around the sun at a speed of about 67,000 miles per hour [mph]. If it takes one year [yr] for the Earth to circle the Sun and we assume the Earth?s orbit is circular, what is the radius of the orbit in units of meters [m]? Use an appropriate SI prefix to report your answer so there are one, two, or three digits to the left of the decimal point.arrow_forward
- The Earth is about 12,000 km in diameter. It is therefore how many orders of magnitude wider than you are tall? (i.e., the Earth’s diameter is how many times larger than your height (give an order-of-magnitude estimate)?) (I am 5'2")arrow_forwardA car is 16 feet, 3 inches long. How long is it in meters? Use the fact that 1 inch=2.54 centim-eters to determine your answer. Explain your reasoning briefly.arrow_forwardOn a 1:200,000 map, what does a length of 50 mm represent?
