Example: x = 47% × 360° Note: To change a percent number to a decimal number, move the decimal to the left two places and remove the percent sign. 2° = 169° 4. Draw the 169° angle of arc on the circle by first drawing a horizontal line from the left side of the circumference to the center of the circle. 5. Position the protractor on this line and mark 169° as accurately as possible on the circumference.
Html 21/02/2004 Document Página 1 de 2 Page 28 Example: Foucault's original pendulum was located in Paris, which is at latitude 47° N. Calculate the apparent shift of the pendulum's path in degrees per hour. 97° per hour Use the example to determine the shift of a Foucault pendulum at your latitude. b. It takes 24 hours for the pendulum to make an apparent 360° shift at either the North or South Pole, but it takes longer at the lower latitudes. The time (t) it takes for the pendulum to make an apparent shift through a complete revolution of 360° at a specific latitude can be calculated by using this equation: t = 360°/d where d is the apparent shift of the pendulum's path in degrees per hour, as calculated in the previous experiment.
For information about the Moon's phases, see Dinah Moché, Astronomy (New York: Wiley, 1996), pp. 196–197. 3. The Moon and the Sun both rise and set in the general direction of from east to west. In the new moon phase, the Moon rises with the Sun and travels close to it across the sky. The Moon rises about 50 minutes later each day in relation to the Sun. 1 shows the approximate time of moonrise for four moon phases during a synodic month. 2. 2 Get the Facts The Earth and the Moon both make shadows.
