Determine if you would rather use hydraulics or pneumatics.  A) You want something cost efficient

B) You want to move a heavier load with equal input

C) You want to use it for a pipeline underwater to travel long distances

List two other advantages/ disadvantages of both

i'm just gonna leave this comment here, so i can get a challange done-

explanation:

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas
