518,400s - 20A physics teacher drops a ball from a height, the students below time how long it takes the ball to fall, they have the following times. Student 1: 4.48s student 2: 4.85s Student3: 5.06s Student 4: 5.12s what is the absolute error taken by student 4?Using Ea=I M-average of MI
Average of M=(4.48s+4.85s+5.06s+5.12s)/4
average of M=4.88s
|5.12s-4.88s|= .24s - 21What is the relative error student 4?Er=(Ea/average of M) x100%
Er=(.24s/4.88s)x100%
Er=4.9%
