A thin rod extends from x-o to x= 13.0 cm. It has a cross-sectional area A= 6.00 cm2, and its density increases uniformly in the positive x-direction from 2.50 g/cm3 at one endpoint to 18.5 g/cm3 at the other. (a) The density as a function of distance for the rod is given by p-B+ cx, where B and C are constants. What are the values of B (in g/cm3) and C (in g/cm4)?

My Notes + Ask Your Teacher John is pushing his daughter Rachel in a wheelbarrow when it is stopped by a brick 8.00 cm high (see the figure below). The handles make an angle of a = 20.0° with the ground. Due to the weight of Rachel and the wheelbarrow, a downward force of 405 N is exerted at the center of the wheel, which has a radius of 15.0 cm....

My Notes Ask Your Teacher The circuit in the figure below consists of two identical, parallel metal plates connected to identical metal springs, a switch, and a 128-V battery. With the switch open, the plates are uncharged, are separated by a distance d = 7.55 mm, and have a capacitance C = 2.00 pF. When the switch is closed, the distance between the plates decreases by a factor of 0.500 (a) How...
