big animals live longer than small ones? Cats live longer than mice. Horses live longer than cats. And elephants live longer error propagation formula for division than horses. Perhaps surprisingly, the life span of animals is related to their

one-quarter power. (One-quarter power is the same as taking the fourth root or as taking the square root twice.) C is the proportionality constant1 Using this law, we can easily https://www.youtube.com/watch?v=V0ZRvvHfF0E compare the life expectancy for different animals. For example, let's calculate the average life span of an elephant. The average weight of a male elephant is 6,000 kg ± 1,000 kg. 6,000,000 (we converted kg to gr) raised to the one-quarter power is 49.5. Thus the average life span of an elephant is 49.5 years. African Elephant. Image: Courtesy of African Wildlife Foundation. What https://phys.columbia.edu/~tutorial/propagation/tut_e_4_4.html should we do with the error? Raising to a power is related to products. For example, the power of 2 is nothing more than taking a product of a number with itself, y × y. We already know the rule for products − add relative errors2 − so the resulting relative error for y × y is two times the relative error of y. Similarly, for other powers 3, 4, 5, ... the relative error of the result is the relative error of the original quantity times the power to which it is raised. What about fractional powers like 1/2? Well, 1/2 is the square root, which is the reverse of squaring, so the relative error calculation should also be reversed. In the case of the squaring, we multiplied the relative error by two. In the case of the square root, we should divide the relative error by two, which is the same as multiplying it by 1/2. Similarly, for other fractional powers 1/3, 1/4, ... we simply multiply the relative error by the power. So no matter what the power is, fractional or not, the rule is always the same: the rela
or more quantities, each with their individual uncertainties, and then combine the information from these quantities in order to come up with a final result of our experiment. How http://lectureonline.cl.msu.edu/~mmp/labs/error/e2.htm can you state your answer for the combined result of these measurements and their uncertainties scientifically? The answer to this fairly common question depends on how the individual measurements are combined in the result. We will treat each case separately: Addition of measured quantities If you have measured values for the quantities X, Y, and Z, with uncertainties dX, dY, and error propagation dZ, and your final result, R, is the sum or difference of these quantities, then the uncertainty dR is: Here the upper equation is an approximation that can also serve as an upper bound for the error. Please note that the rule is the same for addition and subtraction of quantities. Example: Suppose we have measured the starting position error propagation formula as x1 = 9.3+-0.2 m and the finishing position as x2 = 14.4+-0.3 m. Then the displacement is: Dx = x2-x1 = 14.4 m - 9.3 m = 5.1 m and the error in the displacement is: (0.22 + 0.32)1/2 m = 0.36 m Multiplication of measured quantities In the same way as for sums and differences, we can also state the result for the case of multiplication and division: Again the upper line is an approximation and the lower line is the exact result for independent random uncertainties in the individual variables. And again please note that for the purpose of error calculation there is no difference between multiplication and division. Example: We have measured a displacement of x = 5.1+-0.4 m during a time of t = 0.4+-0.1 s. What is the average velocity and the error in the average velocity? v = x / t = 5.1 m / 0.4 s = 12.75 m/s and the uncertainty in the velocity is: dv = |v| [ (dx/x)2 + (dt/t)2 ]1/2 = 12.75 m/s [(0.4/5.1)2 + (0.1/0.4)
