EASY QUESTIONS! DUE IN 15 MIN WILL MARK BRAINLIEST. 1. What is the sum of a vector 8 m south and a vector 12 m north? *
2. What is the sum of a vector 12 m north and a vector 8 m north? *

PLEASE SHOW WORK AND EXPLAIN

Explanation:

As they are in same direction, you can add them directly. And result is 12 + 8 m = 20 m North. If you use vector addition: Vectors = 12m & 8 m & angle b/w them is 0°(as both are in same direction).

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27
