the distance travelled by an object in time hundred plus minus one years is 5.2 plus minus 0.1 M what is the speed and its error |
|
Answer» 19.23 ± 0.56 m/s.Explanation:From the QUESTION we GET that distance = 100 ± 1 seconds and the time = 5.2 ± 0.1 m.So, we know that Speed = Distance/Time. HENCE, the Speed = 100/5.2Speed = 19.23 m/s. Since, for every value there is an error in the data, hence we let that Δx be the error in speed.So, we get that Δx/x= Δa/a + Δb/b im which a is the distance and b is the time.Δx/x=0.1/5.2 + 1/100Δx/x= 0.019 + 0.01So, on calculating Δx/x=0.029Hence, Δx = 19.23 × 0.029Therefore, Δx = 0.56Consequently the Speed will be FOUND to be = 19.23 ± 0.56 m/s. |
