Ahorizontal pipeline is 660 mm in diameter and carries oil at a rate of 150 kg/s. this oil has a mass density of 850 kg/m3 and a viscosity of 0.224 pa⋅s at the temperature of the pipelineif the pressure in the oil is 3.75 atm at the front end, how long can the pipeline be so that the pressure at the far end is no less than 2.50 atm

Herbivores, carnivores, and omnivores are all types a. decomposers b. producers c. consumers d. biomes

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
