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.​

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
