An hydraulic press has two pistons, the smallest has an area of 20cm2. What would be the largest area so it can apply a force of 180 N in the smallest piston so the output force should it be 600

divide the right side by the left side

0.024÷1.2=0.02 for example

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

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
