Time of flight, and range using the snipping tool, copy and paste the table 1 (time of flight word document, to be printed and attached to this report (do not print the document yet): vs. intitial speed) into a microsoft use equation 2a from the theory to calculate the time of flight: t s. to n n latnoshod at bwol elaz3 tholduob ue average tof from table 1: initial velocity 1 0a4. m/s; time 0.442 s; % difference initial velocity 2 307 ,m/s; time 0.442, s; % difference (% difference is determined with respect to the calculated t) predicted horizontal range ax ,m. attached the page with the marks from carbon paper. estimate the average distance from your predicted impact point marked with an "x" and the actual impact sites: , m. calculate the percent error with respect to the predicted ax: % d conclusion (part i) explain your results was the tof different for different initial speed? why or why not? how well did your predicted range compare to the actual range? discuss possible experimental errors. was is reasonable to neglect air resistance?

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.)

I'm thinking it's 2 you are asked to explain the earth's magnetic field. which is the best reply? 1. the earth's magnetic south is similar to the north pole of a magnet. 2. the earth's core has a strong magnetic charge similar to the south pole of a magnet. 3. the earth's geomagnetic south is similar to the south pole of a magnet. 4. the earth's magnetic charge is not centered at either pole; it varies based on location.
