two objects move toward each other collide and separate. there was no net external force acting on the objects but some kinetic energy was lost. is momentum conserved ? what is the explanation ?
= 27600 X 100/115 = 24000
An object with mass 20 kg is moving horizontally. if the velocity of the object is doubled, does the momentum increased or decreased ? what is the explanation ?

Why all enzyme work well in their own optimum temperature and optimum pH ? i need more explanation about why different enzyme have different optimum temperature and different optimum pH to react. i hope to get a long explanation for my essay that contain 5 marks.
According to the Professor Sandel, if judgments about the good are unavoidable in debates about justice and rights, is it possible to reason about the good (these judgments about the good)? a) If reasoning about the good means that you must have a single principle or rule or m...
Do all enzymes function within the different temperature range, like they do with pH?
