The hanging ball in each frame shown in the is stationary, explain why Next show that | cout| = mg tan theta Refer to Figure 4 below, and find the equation for tan theta as a function of x and L. Hint: Start by using the approximation for very small angles that tan 6 % sin 6 so then the lengths y and L can be assumed to be almost equal, provided that x ball L Combine the equations you derived in parts (c) and (d) to find the equation needed to calculate the experimentally determined magnitude of the Coulomb force as a function of L, x ball, m, and the local gravitational constant g.

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
