Question

which of the following is a proper way to label the vector above? use the scale of 1 cm = 1 meter. 45 m 45 m north east 45 m, 30 degrees ccwe 45 m at 30 degrees east of north

Explanation:

Step1: Analyze the first option

A vector must have both magnitude and direction. The first option “45 m” only has magnitude, no direction. So it is incorrect.

Step2: Analyze the second option

“45 m North East” is too vague. A proper vector label should have a more precise angular measurement. So it is incorrect.

Step3: Analyze the third option

“CCWE” is not a standard way to denote direction. Usually, we use standard compass - related angular descriptions. So it is incorrect.

Step4: Analyze the fourth option

“45 m at 30 degrees East of North” gives both the magnitude (45 m) and a clear angular direction (30 degrees East of North). This is a proper way to label a vector.

Answer:

45 m at 30 degrees East of North
