Weegy: According to Ptolemy's model of the movement of celestial bodies,: C. planets orbit in circular paths around the earth. User: An object has a mass of 120 kg on the moon. What is the force of gravity acting on the object on the moon? A. 196 N B. 1,176 N C. 20 N D. 12.24 N Weegy: C. 196 N User: Oil flows upward in the wick of a lantern because of the liquid property called A. density. B. viscosity. C. meniscusity. D. capillarity. Weegy: Oil flows upward in the wick of a lantern because of the liquid property called A. [ viscosity. 'When fluid is forced through a tube, the fluid generally moves faster near the axis and very slowly near the walls, therefore some stress is needed to overcome the friction between layers and keep the fluid moving. For the same velocity pattern, the stress required is proportional to the fluid's viscosity.' ] User: An object with a mass of 78 kilograms is lifted through a height of 6 meters. How much work is done? A. 47.75 J B. 764.4 J C. 4,586.4 J D. 468 J Weegy: D. [ 4,586.4 J use the formula W = mgs W stands for work done in joules m stands for mass of the object g stands for gravity s stands for the distance the object is lifted W = mgs W = 78kilograms 9.8m/s2 6meters W = 4586.4 J (joules) answer would be 4,586.4 J ] User: A tank with a flat bottom is filled with water to a height of 4 meters.
