Question
derstanding Vector Addition 15 of 15 two vectors, the resulting vector's components are the sums of the corresponding components of the original vectors aming Goal: learn to add vectors. For instance, consider the two vectors A and B with components (ar,a)and (by) respectively If you want to find the sum A + B, then you would simply add the x components to get the resuling x component and add the y components to get the resulting y component physics, many important quanties-from the simple undations of mechanics such as position and force to ery foreign ideas such as electric current densities and agnetic fields-are vectors Simply knowing whata ector is heips understanding, but to really use the ideas of physics and predict things, you need to be able to do calculations with those vectors. The simplest operation you might need to perform on vectors is to add them For the situation of you swimming across the river from left to right, use a standard set of coordinates where the x axis is horizontal, with positive pointing to the right and the y axis is vertical, with positive pointing upward Part C Which of the following gives the correct components for the current velocity and the pure swimming velocity (ie the velocity that you would have in still water) using this coordinate system? current (1.00 m/s 0.00 m/s), swimming (0.00 m/s 1.00 m/s) curent (0.00 m/s.1.00m/s), swinming (1.00 m/s0.00 m/s Figure curtent(-1.00 m/s0.00 ms) swimming (0,00 m/ 1.00 m) 2of2 Ocurrent (0.00 m/s1.00 /s) swimming1.00 000 m/s) O current (0.00m/ 1.00 m/s) swiming (1.00 /s 0.00 m/s) Submit A vector of aero length Part D This question wai be shown aner you complete previous q uestons) Part E This question will be shovwn ater you complete previous questiongs)Explanation / Answer
C)
option A) is correct
current is x-direction and swimming in y-direction
hence
if is single correct question , then only option A) is correct
if multi-correct
then option A) and C) are correct
