9. Three vectors A, B and are of magnitudes 10 units, 5 unit and 10 unit respectively. If they make angles 30°, 120° and 300' with X-axis (and all lie along the X - Y plane), then determine the magnitude of the resultant 1155 2) 515 3) 10/3 4) 105

What are similarities and differences between refraction, reflection, diffraction and absorption?

You charge a parallel-plate capacitor, remove it from the battery, and prevent the wires connected to the plates from touching each other. when you increase the plate separation, what happens to the following quantities?

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?
