Now that you've measured the distance to the lodge in (virtual) centimeters, let's make the following assumptions in order to calculate a gas budget for the ski trip. One virtual centimeter on the map above corresponds to 33 miles in actual distance; your vehicle gets 15 miles per gallon of gasoline; and gasoline costs $2.63 per gallon. Cepheid Variable Star Exercise 2 A Cepheid variable star is yellowish supergiant whose brightness varies in a periodic way, over and over, as time passes. As it turns out, the period (or cycle duration) is an important tool for measuring the size and age of the universe. Using the ruler as instructed below, measure the period of one Cepheid variable from its light curve (a graph of the star's brightness versus time). Each numbered tick mark on the ruler represents one centimeter. Enter the cycle length in centimeters and in days in the boxes below. Sunspots Exercise 3 Our Sun displays large numbers of sunspots for many months, only to then become relatively featureless for several years. Sunspot maximum coincides with frequent displays of the aurora borealis (and australis)—the Northern and Southern Lights. On the other hand, "solar max" also coincides with solar storms that can disrupt the power grid and satellite communications. This exercise gives us an opportunity to measure the average duration of the sunspot cycle. Each numbered tick mark on the ruler represents one centimeter. a. What is the scale of the x-axis of the sunspot graph? b. What is the average number of years between peaks in the sunspot cycle? Time in Days Enter the cycle length in centimeters and in days in the boxes below x cm X. 5 days 1 cm O days Sunspots Exercise 3 Our Sun displays large numbers of sunspots for many months, only to then become relatively fea Southern Lights.On the other hand, "solar max" also coincides with solar storms that can disrupt cycle.Each numbered tick mark on the ruler represents one centimeter. 1cm= years 0 years 1 cm cm X 0 years 7 8 (a)What is the scale of the x-axis of the sunspot graph?
