When an electrical appliance whose power usage is X watts is run for Y seconds, it uses X x Y joules of energy. The energy unit used by electrical utilities in their monthly bills is the kilo watt hour ( kwh, that is 1 kilowatt used for 1 hour ) how many joules are there in in a kilowatt hour ? If electricity cost $0.09 per kilo watt hour how much does it cost per megajoule?

1.22 In order to prevent frostbite to skiers on chair lifts, the weather report at most ski areas gives both an air temperature and the wind-chill temperature. The air temperature is measured with a thermometer that is not affected by the wind. However, the rate of heat loss from the skier increases with wind velocity, and the wind-chill temperature is the temperature that would result in the same rate of heat loss in still air as occurs at the measured air temperature with the existing wind. Suppose that the inner temperature of a 3-mm-thick layer of skin with a thermal conductivity of 0.35 W/m K is and the air temperature is . Under calm ambient conditions the heat transfer coefficient at the outer skin surface is about (see Table 1.4), but in a 40-mph wind it increases to . (a) If frostbite occurs when the skin temperature drops to about , do you advise the skier to wear a face mask? (b) What is the skin temperature drop due to the wind?
When an appliance whose power usage is X watts is run for Y seconds, it uses X x Y joules of energy. The energy unit used by electrical utilities in their monthly bills is the kilowatt-hour(kWh, that is,1 kilowatt is used for 1 hour.) How many joules are there in a kilowatt-hour? If electricity costs $0.09 per kilowatt-hour, how much does it cost per megajoule?
Five objects in a region where the acceleration due to gravity is 30.2 ft/s2 are as follows: x1 = 350 g of mass; x2 weighs 950gf; x3 weighs 25 poundals; x4 weighs 2lbf; x5 is 0.40 slug of mass. What is (a) the total mass expressed in gm, and (b) the total weight expressed in kgf.
Graph below represents the force on a 12 kg air mass as it passes through a jet engine. Immediately after entering the engine, the force is 9,039 N, and the force tapers linearly to zero once the air reaches the back of the engine 2.3 m later. If the air enters the engine with velocity 252 m/s, what is its exit velocity? (Please answer to the fourth decimal place - i.e 14.3225)
The gravitational constant g is 9.807 m/s2 at sea level, but it decreases as you go up in elevation. A useful equation for this decrease in g is g = a – bz, where z is the elevation above sea level, a = 9.807 m/s2, and b = 3.32 × 10–6 1/s2. An astronaut “weighs” 80.0 kg at sea level. [Technically this means that his/her mass is 80.0 kg.] Calculate this person’s weight in N while floating around in the International Space Station (z = 354 km). If the Space Station were to suddenly stop in its orbit, what gravitational acceleration would the astronaut feel immediately after the satellite stopped moving? In light of your answer, explain why astronauts on the Space Station feel “weightless.”
1. Energy consumption in a country from 2001 to 2011 increased from 1041.3 million to 1526.1 million BOE (barrels of oil equivalent). If the high calorific value (HHV) of the oil is 141,000 kJ/gallon what is the increase in energy consumption over 10 years in Joule units. What is the rate of energy consumption per year? 2.
