A large globe, with a radius of about 5 , was built in Italy between 1982 and 1987.
Imaginethat such a globe has a radius and a frictionless surface. A small block of mass
slides starts from rest at the very top of theglobe and
slides along the surface of the globe. The block leavesthe surface

Learning Goal: To understand Newton's law of gravitation and the distinction between inertial and gravitational masses. In this problem, you will practice using Newton's law of gravitation. According to that law, the magnitude of the gravitational force Fg between two small particles of masses m1 and m2 separated by a distance r, is given by m1m2 T2 where G is the universal gravitational constant, whose numerical value (in SI units) is 6.67 x 10-11 Nm2 kg2 This formula applies not...

6 of 9 > there is an electric field Constants Learning Goal Part C To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor Assume that at some point just outside the surface of the conductor, the electric field has magnitude E and is directed toward the surface of the conductor. What is the charge density n on the surface of the conductor at that point? A...

Learning Goal: Part A - Force with a known deflection To solve for forces in statically indeterminate bars with axial loads. When the number of reaction forces is greater than the number of equilibrium equations, the system is slatically indeterminate. Solving for the reactions requires some additional equations. These additional equations come from considering compatibility relationships (.e., continuity of displacements and relationships between displacements and loads). For an axially loaded member, the compatibility relationship for the deflections can be written...

Learning Goal: To analyze and design a passive, second-order bandpass filter using a series RLC circuit. A bandpass filter is needed for an equalizer, a device that allows one to select the level of amplification of sounds within a specific frequency band while not affecting the sounds outside that band. The filter should block frequencies lower than 1.8 kHz and have a resonant frequency of 5.4 kHz A 3.2 AF capacitor and any needed resistors and inductors are available to...

Learning Goal: To relate current, time, charge, and mass for electroplating calculations. Electroplating is a form of electrolysis in which a metal is deposited on the surface of another metal. To quantify electrolysis, use the following relationships. Electric current is measured in amperes (A), which expresses the amount of charge, in coulombs (C), that flows per second (s): 1 A 1 C/s Another unit of charge is the faraday (F),...
