Negatively Charged Positively Charged
571 wordsFusion reactions are inhibited by the electrical repulsive force that acts between two positively charged nuclei. For fusion to occur, the two nuclei must approach each other at high speed to overcome the electrical repulsion and attain a sufficiently small separation (less than one-trillionth of a centimeter) that the short-range strong nuclear force dominates. For the production of useful amounts of energy, a large number of nuclei must under go fusion: that is to say, a gas of fusing nuclei m...

Pressure Equals Force Divided Equals Force Divided Air
745 wordsSCIENCE RECERCH PAPER Technology has had a big impact on our world. Today I am going to discus the influence of hydraulics and pneumatics. The basic principal in hydraulics and pneumatics is pressure equals force divided by area (P = F/A). Hydraulics make use of water like the hydraulic lift. Pneumatics makes use of air like the hovercraft for instance. INTRODUCTION The basic principle is pressure equals force divided by area. If the area is small than the pressure used will be less. If the area...

Passive Transport Active Transport
229 wordsThe membrane has a double lipid layer through which fat- soluble substances will move, by passive transport or diffusion. The molecules will only move through if they are small enough. There are globular protein regions, which are hydrophilic. These regions allow water and water soluble substances through, but only if they are small enough, for example starch grains are too big. These substances move through by passive transport or diffusion. Diffusion is the passive movement of substances from ...

Ozone Layer Uv Rays
615 wordsWhat is ozone? Why do we need it? Until recent history the general population didn t know the answer to these questions. In our blindness we have consistently and steadily been destroying it, not on purpose but by our own ignorance and need for our high quality of life. We have been releasing harmful chemicals into our atmosphere. So what really is this ozone? Quite simply it is a invisible shield surrounding the Earth protecting us from the fierce uncontrolled sun. The sun is so powerful it pro...
