Questions and Answers

Based on the provided information, what is the most likely type of problem being presented?

  • Finding the angle between two vectors (correct)
  • Determining the magnitude of a single vector
  • Calculating the dot product of two vectors
  • Solving for the components of a vector

    • What is the angle between vectors A and B represented by the diagram?

  • The angle between $\vec{A}$ and $\vec{B}$ can be calculated using the Law of Cosines. (correct)
  • The angle between $\vec{A}$ and $\vec{B}$ is the same as the angle between $\vec{B}$ and $\vec{R}$
  • The angle between $\vec{A}$ and $\vec{B}$ is represented by the corner of the triangle where $\vec{A}$ and $\vec{B}$ meet.
  • The angle between $\vec{A}$ and $\vec{B}$ is always 90 degrees in this scenario.

    • If the angle between vectors A and B is 90 degrees, what can we say about the length of $\vec{R}$?

  • The length of $\vec{R}$ will be greater than the length of $\vec{A}$ or $\vec{B}$. (correct)
  • The length of $\vec{R}$ will be less than the length of $\vec{A}$ or $\vec{B}$.
  • The length of $\vec{R}$ will be equal to the length of $\vec{B}$.
  • The length of $\vec{R}$ will be equal to the length of $\vec{A}$.
