Tanks of compressed gas must be kept away from heat sources. if the temperature of the tank increases too much, it may explode and cause a great deal of damage. which of the following best explains why a tank of compressed gas can explode if it is heated? . a. as the gas is heated, the molecules break apart into individual atoms and move apart. b. as the gas is heated, the molecules move faster and spread out from each other. c. as the temperature of the gas increases, the molecules release energy and move faster. d. as the temperature of the gas increases, the molecules gain energy and move sl

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
