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

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

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

Discover Your Products’ Hidden Potential by Ian C. MacMillan and Rita Gunther McGrath A simple matrix helps you identify the attributes that will make your goods and services most competitive. Why did a minor math error that would occur only once every 27‚000 years so enrage customers that it briefly threatened to derail Intel’s Pentium chip? And how could a feature as trivial as an inexpensive cup holder swing millions of customers to purchase a $17‚000 automobile—particularly when only
