Astraight line is drawn on the surface of a 14-cm-radius turntable from the center to the perimeter. a bug crawls along this line from the center outward as the turntable spins counterclockwise at a constant 45 rpm. its walking speed relative to the turntable is a steady 3.8 cm/s. let its initial heading be in the positive x-direction, where the x- and y-directions are fixed relative to the laboratory. as the bug reaches the edge of the turntable (still traveling at 3.8 cm/s radially, relative to the turntable) what are the x and y components of the velocity of the bug?

The flame produced by the burner of a gas (propane) grill is a pale blue color when enough air mixes with the propane (c3h8) to burn it completely. for every gram of propane that flows through the burner, what volume of air is needed to burn it completely? assume that the temperature of the burner is 195.0°c, the pressure is 1.05 atm, and the mole fraction of o2 in air is 0.210.
