Hi, I need your help with this Physics exercise, I hope you can help me A pulse moving to the right along the x axis is represented by the function of wave: y (x, t) = 2 / (x-3t) ^ 2 + 1 Where x and are measured in centimeters and t in seconds. a) Find the velocity, pulse amplitude, and expressions for the wave function at t = 0s, t = 1.0s and t = 2.0 seconds. b) What would happen if the wave function were: y (x, t) = 2 / (x + 3t) ^ 2 + 1 How would this change the situation?

Use the frequency histogram to complete the following parts. ​(a) identify the class with the​ greatest, and the class with the​ least, relative frequency. ​(b) estimate the greatest and least relative frequencies. ​(c) describe any patterns with the data. female fibula lengths 30.5 31.5 32.5 33.5 34.5 35.5 36.5 37.5 38.5 39.5 0 0.05 0.1 0.15 0.2 0.25 length (in centimeters) relative frequency a histogram titled "female fibula lengths" has a horizontal axis labeled "length in centimeters" from 30.5 to 39.5 in increments of 1 and a vertical axis labeled "relative frequency" from 0 to 0.25 in increments of 0.05. the histogram contains vertical bars of width 1, where one vertical bar is centered over each of the horizontal axis tick marks. the approximate heights of the vertical bars are listed as follows, where the label is listed first and the approximate height is listed second: 30.5, 0.02; 31.5, 0.04; 32.5, 0.05; 33.5, 0.13; 34.5, 0.22; 35.5, 0.25; 36.5, 0.13; 37.5, 0.06; 38.5, 0.09; 39.5, 0.01. ​(a) the class with the greatest relative frequency is nothing to nothing centimeters. ​(type integers or decimals. do not round. use ascending​ order.)

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving

Why are graphs useful when interpreting data
