Suppose you had a 100 gram mass and a 50 gram mass. Both masses appear to be made of the same material, but you can't be sure. You lower the 50 gram mass into a cylinder of water and the water goes from 30.3 mL up to 36.3 mL. The 100-gram mass is also placed in a cylinder of water and the water rises from 30.3 mL to 42.3 mL. Does the experiment provide evidence that the two masses could be made of the same material? Explain!

Iwould sure like to answer your question but i honestly just don’t know

Need more information like a picture

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.

You need to calculate the string in between two masses
