If Marquise is pushing a book towards Nair with 10 Newton of force, and Nair is pushing the book back towards Marquise with 2 Newton of force,
what is the net force acting on the book? *

like poles repel so keep pushing north to north and repels funny to see this

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat

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
