Is it possible for an object’s velocity to increase while its acceleration decreases?A. No, because if acceleration is decreasing, the object will be slowing down.B. No, because velocity and acceleration must always be in the same direction.C. Yes, an example would be a falling object near the surface of the moon.D. Yes, an example would be a falling object in the presence of air resistance.

5) A liquid flows in a tube with a cross-sectional area of \( 0.0002 \mathrm{~m}^{2} \) at a speed of \( 4 \mathrm{~m} / \mathrm{s} \). Calculate: (a) The volume flow rate of the liquid. (b) The speed of flow if the radius of the tube is doubled.

Gasoline flows in a tube with a diameter of 2 cm at a speed of \( 5 \mathrm{~m} / \mathrm{s} \). Calculate: (a) The amount of gasoline flowing per minute. (b) The time required for a tank with a capacity of \( 20 \mathrm{~m}^{3} \) to be filled with gasoli (knowing that \( \pi=3.14 \) )

Water flows through a tube of diameter 2 cm at an average speed of \( 3 \mathrm{~m} / \mathrm{s} \). The end of the tube is closed with a plug with ten holes, each with a radius of 1 mm , calculate the speed of the water flowing from each hole
