Running Head: Energy Conversion Energy Conversion Marlon Walker Professor Abdul Kahn SCI 110: Integrated Science October 21‚ 2011 Abstract Energy conversion has been a topic of debate and research for many years. Scientists conduct experiments in hopes of finding an alternative to relying on burning fossil fuels for electricity. While companies who believe their alternative is the best choice‚ debate over whose source is the “greenest”. Whether it be biomass‚ hydroelectricity‚ solar

physics‚ energy is an indirectly observed quantity which comes in many forms‚ such as kinetic energy‚ potential energy‚ radiant energy‚ and many others; which are listed in this summary article. This is a major topic in science and technology and this article gives an overview of its major aspects‚ and provides links to the many specific articles about energy in its different forms and contexts. The question "what is energy?" is difficult to answer in a simple‚ intuitive way‚ although energy can be

is their difference in momentum? What is their difference in kinetic energy? 2. A 12 g bullet is fired horizontally into a 96 g wooden block initially at rest on a horizontal surface. After impact‚ the block slides 7.5 m before coming to rest. If the coefficient of kinetic friction between block and surface is 0.60‚ what was the speed of the bullet immediately before impact? You have to use the conservation of the total energy of the system to do this problem: Initially‚ you have‚ in the total

which cell has the larger resting membrane potential? Explain. If the permeability to K is higher in A than in B‚ then the resting membrane potential (rmp) will be closer to the equilibrium potential in cell A‚ which means the rmp will be more negative in cell A than in cell B; or in other words‚ the potential difference will be LARGER in cell A. 2. Predict the effect of a reduced extracellular concentration of Na+ on the magnitude of the action potential in an electrically excitable cell. If there

A graded potential in physiology‚ is described as local changes in membrane potential that occur in varying grades or degrees of magnitude or strength. When compared to graded potential‚ an action potential is described as brief‚ rapid‚ large (100mV) changes in membrane potential during which the potential actually reverses so that the inside of the excitable cell transiently becomes more positive than the outside. As with a graded potential‚ an action potential involves only a small portion of
