The slotted arm revolves in the horizontal plane about the fixed vertical axis through point o. the 2.6-lb slider c is drawn toward o at the constant rate of 2.1 in./sec by pulling the cord s. at the instant for which r = 6.1 in., the arm has a counterclockwise angular velocity ω = 4.2 rad/sec and is slowing down at the rate of 3.6 rad/sec 2. for this instant, determine the tension t in the cord and the force n exerted on the slider by the sides of the smooth radial slot. the force n is positive if side a contacts the slider, negative if side b contacts the slider.

State the following: boyle's law and charle's law

7. see worksheet 1 for values of variables x1, x2 and x3 and answer the following questions: a. for each variable find the mean, median, coefficient of skewness, range and population standard deviation. b. compared to variable x1, how are the mean and median affected by extreme values (outliers) seen in x2 and x3. c. is the median or mean the better measure of location for x2 and x3? explain. d. explain the differences in the magnitudes of the skewness coefficients for the three variables. e. what is the relationship between the range and standard deviation looking across the three variables?
