Does This Thing Work? It operates on a 100 year old proven technology called electrolysis. Whenever you place two pieces of metal in water‚ and apply electricity‚ the water separates into it’s basic molecules‚ Hydrogen and Oxygen (H2O). If you look at the picture on the left‚ you will see H2O molecules connected together in their liquid form which is WATER But when you apply electricity (from your car battery)‚ the molecules separate and form a GAS (called HHO) which is a mixture of Hydrogen

THE WORK DONE BY A CONSERVATIVE FORCE ALWAYS HAS FOUR PROPERTIES: 1. It can be expressed as the difference between the initial and final values of a potential-energy function. 3. It is independent of the path of the body and depends only on the starting and ending points. 2. It is reversible. 4. When the starting and ending points are the same‚ the total work is zero. The total mechanical energy ME = K + U is constant. Object moving in a uniform gravitational field gravitational a

Potential Energy • Definition and Mathematics of Work • Calculating the Amount of Work Done by Forces • Potential Energy • Kinetic Energy • Mechanical Energy • Power An object can store energy as the result of its position. For example‚ the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly‚ a drawn bow is able to store energy as the result of its position. When assuming

of the cell increases enormously during the action potential. Comte Whitney Electricity is vital for neural function and communication. The semi-permeable membrane and presence of charged particles in solution (ions)‚ enables the cell to have control of an electric potential. The cell The concentrations of Na+ and K+ ions upon either side of a cell’s membrane are not equal. In order for the equilibrium to be restored‚ sodium will attempt to enter the cell‚ whilst potassium will exit the cell. It is

Investigation: 20 How much cobalt is in the soil? Introduction: By completion of investigation 20‚ a standard curve of absorbance versus known cobalt (II) nitrate was prepared. The concentration of cobalt (II) ion obtained from a soil sample was determined. Whether or not cobalt nitrate should be added to the soil was determined. If cobalt nitrate needs to be added‚ then how much will it be required to meet the necessary nutritional needs of the animals was established. In colorimetry

1.0 Introduction of Investigation Investigation can be defined quite simply as a systematic fact finding and reporting process. It is derived from the Latin word vestigere‚ to “track or trace‚” and encompasses a patient‚ step-by step inquiry. Investigation is finding facts; it is akin to research conducted in the academic arena. Investigation is a multi-disciplined field of study. It encompasses law‚ the sciences‚ communications‚ and a host of other things. Investigation requires an inquisitive

dark and damp surroundings is mainly due to woodlouse’s inefficient water-storage system. A woodlouse‚ if exposed to heat or light for too long‚ can die due to the dramatic loss of water. They prefer a moderate temperature‚ because they are so small‚ and can be damaged by frost if they are exposed to the extreme of cold‚ but they don’t want such a high temperature‚ either‚ because they would start loosing too much water. I would also expect the woodlouse to prefer a surrounding of slightly

POEM ANALYSIS In the poem “Monologue for an Onion” by Suji Kwock Kim‚ the onion metaphor is the centerpiece of the poem. The onion represents the poet‚ and the person she addresses (the reader assumes) is her lover. The onion metaphor is used to convey the message to this anonymous lover that she is by nature heartless and that he should stop trying to unearth a hidden core. The author is trying to dissuade her lover from further fruitless digging which only seems to cause him distress. The speaker

effect to the potato cells in the different solute concentration water Introduction; Water can move through the different cells due to the difference of water potentials in the cells. If there is a higher solute concentration in the cell than outside the cell‚ the water will move into the cell. However‚ if the concentration of inside the cell is lower than the outside‚ water will not move into the cell. This process is called osmosis. Research question; This investigation will determine how
