True or False: The addition of a vector to a point produces a new point.
What is the meaning of the following two images?
These images were inserted here simply to insert some space between the questions and the answers to keep them from being visible on the screen at thesame time.
This image was also inserted for the purpose of inserting space between the questions and the answers.
True
True. In fact, when the lengths of the vectors are the same and they are opposite in direction, the length of the sum of the two vectors is zero.
False. When you add vectors, the order in which you add the vectors doesn't matter. The result will be the same no matter the order in which you add them.
False. If an object is registered as an ActionListener on a button, the actionPerformed method belonging to the object is called each time the user clicks the button.
False. In order to cause a point to remain in the same location relative to world coordinates, its values relative to the current coordinate frame must bemodified each time the coordinate frame is modified.
True
False. The head-to-tail rule applies for the sum of any number of vectors in any number of dimensions (but it is difficult to draw in more than threedimensions).
False. It doesn't matter whether or not the coinciding tails are drawn at the origin. The head-to-tail rule still holds true.
True. This is a description of the head-to-tail rule.
False. While it's legal to draw a vector anywhere in space, certain positions may have advantages over other positions in some cases.
True
False. When you draw a vector, you can draw it anywhere in space, and one position is equally as valid as any other position.
True
False. The sum of a vector and a point is another point .
False. The length of a 2D vector is equal to the length of the hypotenuse of a right triangle formed by the lengths of the horizontal and vertical componentsof the vector.
True
