This is what i found on google “kinetic energy. energy is transferred from one object to another when a reaction takes place. energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few. this energy would be in the form of motion, with the person lifting the blue ball to a higher level.” i hope this you

Gas will most likely  fill the container 

The answer would be a) -80of

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.
