13. Vectors Quiz Answers

Answer to Quiz #1

The magnitude of the vector is:

a2+b2+c2\sqrt{a^2+b^2+c^2} .

The format you need to use in the workspace is: \sqrt{a^2+b^2+c^2}.

Answer to Quiz #2

After finding the addition, visualize the vector. Draw it and you will see how simple it is to find the correct answers.

  • Magnitude : 11
  • Direction: 00{^\circ} (write only 00 in the workspace)

Answer to Quiz #3

(a) The magnitude is now:

αa2+b2\alpha\sqrt{a^2 + b^2}.

The format you need to use in the workspace is: \alpha\sqrt{a^2 + b^2}.

(b) Will the direction change?

no

(c) The direction will change by 180180{^\circ}

(write only 180180 in the workspace)

(d) The magnitude will

decrease
