If the statement is false, correct the statement to make it true. 12. An object in uniform circular motion has a constant velocity while experiencing centripetal acceleration. 13. An object travelling in uniform circular motion experiences an outward centrifugal force that tends to pull the object out of the circular path. 14. An object with less inertia can resist changes in motion more than an object with more inertia. 15. For an object sliding on a horizontal surface with a horizontal applied force, the frictional force will always increase as the applied force increases.arrow_forward

The infinitely long cylinder is pushed upward at a constant velocity. The diameters of the cylinder and piston are 10 cm and 9 cm, respectively, and there is oil between them with v = 10⁻⁴ m^2/s and γ = 8,000 N/m³. At what speed must the cylinder ascend for the piston to remain at rest?arrow_forward
