An electric car is powered by an electric motor instead of a gasoline engine. The electric motor gets energy from a controller‚ which regulates the amount of power transmitted throughout the vehicle‚ based on the driver’s use of an accelerator pedal. The electric motors give electric cars instant torque‚ creating a strong and smooth acceleration pattern. Electric cars are about three times more efficient than cars with an internal combustion engine. A pure-battery electric car uses energy stored

Compare and contrast CAPM and APT? Capital asset pricing model (CAPM) and arbitrage pricing theory (APT) are both methods of assessing an investment’s risk in relation to its potential reward and whether the potential investment yield is worthwhile. CAPM developed by Sharpe 1964. The basic theory behind this model is that investor needs to be compensated for Time Value of Money and the risk that they are taking. The time value of money is represented by the risk-free (rf) rate in

produced? Have you ever noticed how your hair stands straight and stiff when you comb it vigorously on a dry‚ cold day? Or how difficult it is to remove dust particles from your comb? Your hair and the comb become charged by rubbing. This stationary electric charge is described as static electricity. Activity 1. Rub a plastic sheet with flannel and then hold the plastic sheet near Styrofoam bits. What do you observe? From the observations made‚ you can conclude that rubbing produces static electricity

The electron is a fundamental subatomic particle that carries a negative electric charge. It is a spin-½ lepton that participates in electromagnetic interactions‚ and its mass is less than one thousandth of that of the smallest atom. Its electric charge is defined by convention to be negative‚ with a value of −1 in atomic units. Together with atomic nuclei‚ electrons make up atoms; their interaction with adjacent nuclei is the main cause of chemical bonding. The name "electron" comes from
