which observation illustrates the law of coservation of mass?
Which observation illustrates the law of conservation of mass? The C:O mass ratio of one compound is exactly double that of another compound. When 3 g of carbon reacts with 8 g of oxygen, 11 g of carbon dioxide is produced. The C:O mass ratio of a particular compound is the same, regardless of the size or source of the sampl O Burning 10 g of propane produces twice as much...

To understand the use of Hooke's law for a spring. Hooke's law states that the restoring force F⃗ on a spring when it has been stretched or compressed is proportional to the displacement x⃗ of the spring from its equilibrium position. The equilibrium position is the position at which the spring is neither stretched nor compressed. Recall that F⃗ ∝x⃗ means that F⃗ is equal to a constant times x⃗ . For a spring, the proportionality constant is called the spring constant and denoted...

A spring, of negligible mass and which obeys Hooke's Law,
supports a mass M on an incline which has negligible friction. The
figure below shows the system with mass M in its equilibrium
position. The spring is attached to a fixed support at P. The
spring in its relaxed state is also illustrated. Mass M has a value
of 255 g. Calculate k, the spring constant. The mass oscillates
when given a small displacement from its equilibrium position along
the...
