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

Broken Windows Disorder is defined as the disruption of peaceful and law-abiding behavior. Malcolm Gladwell uses this word to explain the cause of chaos and epidemic when it comes to crime in cities. In Gladwell’s passage‚ The Power of Context‚ he describes disorder as an epidemic which results from a small‚ single event‚ referred to as the “broken window” and which can instigate and influence the behaviors of those in the community. In the Power of Context‚ Gladwell describes disorder as something

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

Market Audit and Competitive Market Analysis Executive summary The lack of access to mosquito nets and coils and to sanitation systems are central public health concerns‚ globally and in Rwanda. No single intervention has greater overall impact upon national development and public health than does the provision of mosquito nets and coils. Inadequate mosquito nets and coils contribute to 70 percent of diseases in Rwanda. In 2000‚ 40% of outpatient visits to health facilities were for malaria and
