2. Many products that we use in our daily lives are derived from geologic materials from the Earth, otherwise known as natural resources and can be renewable or non-renewable. One of the more prominent of these materials is fossil fuels (oil and coal), a non-renewable resource which provides energy to do work.

(b) High voltage electric power transmitted to a city is dropped to a low voltage in a transformer before use. To keep the transformer at a steady temperature, heat (called the Joulean power dissipation) needs to be transferred to an ambient. Assuming the transfomer to be a vertical cylinder with a diameter of 0.4 m and height of 1 m, the walls are kept at 90°C in a stagnant fluid bath Determine the allowable heat dissipation if the fluid is...

plz re-phrase the folloowing data :- Energy need globally expanded by 2.3per cent this past year, its rate that is fastest this ten years, a performance that is excellent by way of a robust international economy and more powerful cooling and heating requirements in a few areas. Propane emerged because of the understood reality gas of choice, publishing the maximum gains and accounting for 45% connected with boost in power usage. Petrol need development ended up being particularly strong in...
