No. 6 fuel oil has a carbon content of 20 kg carbon per 109 j. if it is burned in a 40 percent efficient power plant, find the carbon emissions per kilowatt-hour of electricity produced, assuming all of the carbon in the fuel is released into the atmosphere. by law, new oil-fired power plant emissions are limited to 86 mg of so2 per million joules (mj) of thermal input and 130 mg nox/mj. estimate the maximum allowable so2 and nox emissions per kilowatt-hour.

Asled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slidesa distance d1 down the slope and then covers the distance d2 alongthe horizontal terrain before stopping. find the coefficient ofkinetic friction μk between the sled and the ground, assumingthat it is constant throughout the trip. find the coefficient of kinetic frictionμk. express your answer in terms of someor all of the variables d1, d2, and θ.
