q14

A Foucault pendulum is a simple device used to observe the rotation of the Earth. If the pendulum needs to have a period of 6.74 seconds, how long does the Foucault pendulum need to be (in meters)? Type your answer.

[#167] Components of vectors The vector à in the (x, y) plane has magnitude A = 3.2 and makes angle 0 = 125° with the x axis, where 0 is measured in the geometric or anticlockwise sense. What are the components of à in the x and y directions? Hint: draw a sketch first. Write your answer in the form: x, y. For example: 1.5, 2.0 Use the correct number of sig figs and think about the sign.

Dimensional Analysis: Often, we can almost derive formulas (up to an overall constant) just by knowing the units of the relevant quantities. Under the assumption that the pendulum's period can only depend on the pendulum's length L, mass m, maximum angle 0, and the strength of gravity g (with units [g]=m/s²), explain why we must have a relation like T = f(0) × √2 (Note that counts as a unitless parameter here.) Asserting f(0) ~ ƒ(0) in this formula is the small angle approximation (where f(0) = 2π is found by other means).

Write down the value you read from the figure in units of mm. Pay attention to use the correct number of significant figures.

Use dimensional analysis to determine how the period T of a swinging pendulum (the elapsed time for a complete cycle of motion) depends on some, or all, of these properties: the length L of the pendulum, the mass m of the pendulum bob, and the gravitational field strength g (in m/s2). Assume that the amplitude of the swing (the maximum angle that the string makes with the vertical) has no effect on the period.
