Find the liquid pressure at the bottom of a 50m deep container that carries ethyl alcohol. For the following problem, assume a constant temperature. With an initial pressure of 500pa, what is the final pressure inside a container after it undergoes a volume change from 10 m^3 to 2m^3? A 25kg sphere is balanced on top of a table. The sphere covers an area of 10m^2. What is the pressure applied to this table? Draw the electric field lines between...
A block of mass .5kg is ona table and attached to a block of mass .25kg by a taut massless string. The .25kg block hangs by means of the string, which goes over a pulley. The .25kg block is released, and it descends from rest at a constant acceleration, travelling 1.00m in 1.25s. What is the coefficient of kinetic friction between the table and the .5kg block?

What is the total volume of the Ice sheet? It covers an area of 1,710,000 km2 with an average depth of 1.5 km.
A sphere with a mass of 8kg and diameter of 25cm is initially on top of a ramp at rest with an angle of 30 degrees with a base length of 5 meters. The sphere rolls down the ramp with an initial velocity of 3 m/s. a) What is the final velocity of the sphere at the bottom of the ramp if the coefficient of friction is 0.3 [I=2/5 mr^2] b) Calculate the revolutions per second of the sphere from...
(a) A sphere and a cylinder are released from the top of an inclined plane and roll without slipping to the bottom. Which one gets there first? (explain your answer and show calculations) [2 Marks] (b) What does it mean to say that an object is dynamically balanced? How is this different to an object being statically balanced? [1 Mark] (c) Under what conditions can we apply techniques from 2-dimensional (planar) rigid body mechanics to 3-dimensional objects? [1 Mark] (d)...
The top and bottom surfaces of a metal block each have an area of A = 0.025 m2, and the height of the block is d = 0.12 m. At the top surface of the block, a force F1 is applied to the right, while at the bottom surface of the block, a force F2 is applied to the left, causing a shear in the metal block. If F1 = F2 = 41 ✕ 106 N and the displacement between...
