A35 kg box rests on the back of a truck. the coefficient of static friction bet? 005 (part 1 of 2)a 35 kg box rests on the back of a truck. thecoefficient of static friction between box andtruck bed is 0.202.the acceleration of gravity is 9.8 m/s2 .when the truck accelerates forward, whatforce accelerates the box? 006 (part 2 of 2)
what maximum acceleration can the truck
have before the box slides?
answer in units of m/s2.

Acoal-fired plant generates 600 mw of electric power. the plant uses 4.8 x 10^6 kg of coal each day, and the heat of combustion of coal is 3.3x 10^7 j/kg. the steam that drives the turbines is at a temperature of 300° c, and the exhaust water is at 37° c. (a) what is the overall efficiency of the plant for generating electric power? (b) how much thermal energy is exhausted each day? (c) what is the change in entropy of the universe for this heat engine? (d) using the same heat reservoirs, what is the maximum possible (carnot) efficiency for a heat engine?

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

Selma made a diagram to compare convection and radiation. which label belongs in the area marked x? must involve temperature differences between substances or objects only occurs when molecules are in direct contact involves the movement of fluids based on density differences can occur where there is little or no matter
