Design an experiment‚ based on the principles of diffusion and osmosis‚ that the assistant could use to determine which of the flasks contains each of the four unknown solutions. Include in your answer: a. a description of how you would set up and perform the experiment; b. the results you would expect from your experiment; and c. an explanation of those results based on the principles involved.

KINETIC ENERGY Objects have energy because of their motion; this energy is called kinetic energy. Kinetic energy of the objects having mass m and velocity v can be calculated with the formula given below; K=1/2mv² Kinetic energy is a scalar quantity; it does not have a direction. Unlike velocity‚ acceleration‚ force‚ and momentum‚ the kinetic energy of an object is completely described by magnitude alone. Like work and potential energy‚ the standard metric unit of measurement for kinetic energy

Kinetic theory (or the kinetic or kinetic-molecular theory of gases) is the theory that HYPERLINK http//en.wikipedia.org/wiki/Gasgases are made up of a large number of small particles (HYPERLINK http//en.wikipedia.org/wiki/Atomatoms or HYPERLINK http//en.wikipedia.org/wiki/Moleculemolecules)‚ all of which are in constant‚ HYPERLINK http//en.wikipedia.org/wiki/Randomnessrandom HYPERLINK http//en.wikipedia.org/wiki/Motion_(physics)motion.

Kinetic Energy: Consider a baseball flying through the air. The ball is said to have "kinetic energy" by virtue of the fact that its in motion relative to the ground. You can see that it is has energy because it can do "work" on an object on the ground if it collides with it (either by pushing on it and/or damaging it during the collision). The formula for Kinetic energy‚ and for some of the other forms of energy described in this section will‚ is given in a later section of this primer. Potential

Kinetic Art Kinetic art: the art of motion. Kinetic art contains a/or several moving parts and depends on motion for its effect. The motion of the art work can be provided in virtually any way. It can be powered by natures elements; wind‚ wave power from water‚ or heat from a fire; It can also be powered mechanically through electricity‚ steam‚ clockwork using earths natural phenomena’s ‚ gravity‚ motors‚ or even through the observer such as cranking a handle‚ or giving a push.

Biology “Enzyme Activities” Introduction: Enzymes have extremely interesting properties that make them little chemical-reaction machines. The purpose of an enzyme in a cell is to allow the cell to carry out chemical reactions very quickly. These reactions allow the cell to build things or take things apart as needed. This is how a cell grows and reproduces. At the most basic level‚ a cell is really a little bag full of chemical reactions that are made possible by enzymes (Brain). Laboratory

CHAPTER 4: ENZYMES Enzymes are biological catalysts. There are about 40‚000 different enzymes in human cells‚ each controlling a different chemical reaction. They increase the rate of reactions by a factor of between 106 to 1012 times‚ allowing the chemical reactions that make life possible to take place at normal temperatures. They were discovered in fermenting yeast in 1900 by Buchner‚ and the name enzyme means "in yeast". As well as catalysing all the metabolic reactions of cells (such as respiration

The idea of kinetic art is getting a bit of a workout at the moment. MIT Museum recently hosted “year of kinetic art‚ including “5000 Moving Parts‚” a kinetic art exhibiton featuring large-scale works by Arthur Ganson‚ Anne Lilly‚ Rafael Lozano-Hemmer and John Douglas Powers. Plus the Kinetic Art Organization has published a digital “International Collection of Essays About Kinetic Art—2013—volume 1.” The two don’t overlap: The MIT show highlights a somewhat different segment of artists working

But I think it happened because the blow dryer only focuses on one point so it doesn’t effect the other vanes. When I used the power of wind‚ I realized that the result was so much

What is Enzyme? Enzymes are protein that acts as speed up reactions and break down molecules in our body. However‚ different enzymes only work on certain types of molecules. Enzymes can accelerate the reactions by more than one million times.(3) In our human body‚ there are a total about forty thousand types of enzymes and each catalyzes different kind of molecule.(3) The molecules that enzymes help to accelerate is called substrates‚ and when enzyme is combined together with the substrate‚ it
