4. Consider a lightbulb rated for a power of 20 watts. This lightbulb consumes a certain amount of electrical energy in 1 second of use. Suppose we want to generate the same amount of energy by dropping from height to ground level. If the mass of the lightbulb Is 0.050 kg, what is h or the height?
In recent years, there has been a large push for an increase in the use of renewable resources to produce the energy we need to power our
vehicles. One of the newer fuels that has become more widely available is E85, a mixture of 85% ethanol and 15% gasoline. Despite
being more environmentally friendly, one of the potential drawbacks of E85 fuel is that it produces less energy than conventional
gasoline. Assume a car gets 27.5 mi gal using gasoline at $3.50/gal and 21.5 mi gal using E85 at $2.85/gal. How much will it cost to drive
700. miles using conventional gasoline fuel?
How much will it cost to drive 700. miles using E85 fuel?

The advantage of the island is the number of different renewable energy potentials. The cost of electricity on the island is $0.39 kWh. 1) Using solar radiation photovoltaic technologies, it was estimated that 500 rooftops, with a total surface area of 456 000 m2 , will be available to install the photovoltaic panels. Assume that the solar panels actually cover 90% of the available surface area. Given, the size of a standard photovoltaic cell is 156 mm by 156 mm and for a silicon photovoltaic cell, each PV cell produces a current of 2.5 A at a voltage of 0.5 V. The average daily irradiance for the island is 185 W/m2 . Assume the initial capacity expenditure evaluated on a year basis of the photovoltaic system, that covers, 90% of the available surface area is US $600 000 and the annual operating cost is US…arrow_forward
