Select one or more: O a. One way to add vectors is to first break them down into the X and Y components, sum up the total X and Y contributions, and then use the Pythagorean theorem and trigonometric equations to get the total vector's magnitude and direction. O b. A vector cannot be multiplied by a scalar. O c. Vectors cannot exist in dimensions higher than 3-D. O d. Velocity is just speed with a direction O e. Every scalar can be turned into a vector by giving it a direction. O f. Two vectors with different units cannot be added together (such as 1km East and 30 km/h West). g. Scalars must have a direction. A h. Temperature is an example of a scalar. O i. Although a scalar can be negative (such as -10C), a vector cannot be negative (such as -1km East).
