Asquare loop of wire lies in the x, y plane with opposite corners at (0, 0) and (a, a). the loop carries a current i directed towards the origin along the y-axis and away from the origin along the x-axis. calculate the cartesian components of the magnetic field b generated by the loop at the point (x, y, z) = (0, 0, a), in terms of a, i, and fundamental constants.

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.

Identify some abiotic characteristics of the tundra biome.

7. see worksheet 1 for values of variables x1, x2 and x3 and answer the following questions: a. for each variable find the mean, median, coefficient of skewness, range and population standard deviation. b. compared to variable x1, how are the mean and median affected by extreme values (outliers) seen in x2 and x3. c. is the median or mean the better measure of location for x2 and x3? explain. d. explain the differences in the magnitudes of the skewness coefficients for the three variables. e. what is the relationship between the range and standard deviation looking across the three variables?
