There are two designs for roller coasters awaiting approval at Disneyland Headquarters in Florida. Both designs use 3000 cm of track and have similar shapes and heights. In Plan one the roller coaster cart completes the 3000 cm course in 20 seconds and in Plan two the cart completes 3000 cm course in 22 seconds. Use what you know about speed calculations to write a short paragraph with recommendations to Disney Executives. Your paragraph must explain which design would be best suited for Marvel Land, an area of Disneyland frequently visited by teenagers. (Answer with the answers put in this sentence pls -->)Dear Disney Executives, It is my recommendation that roller coaster plan _ be placed in Marvel Land. Plan travels at an average velocity of __ where as plan _ travels at an average velocity of __ Teenagers prefer roller coasters that __ making plan __ the perfect choice for Marvel Land.​

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap
