Please help!! :( will mark as brainliest The price of tickets to the Dakota vs. Chippewa football game goes from $6 to $4, which results in a 50% change in demand for tickets. What is the elasticity? What type of product is it?

An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to move. 

Ibelieve the answer is d. macula  hope my answer has you : )

B. elliptical. as in oval. 0 (==

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.
