Add the vector 12.0 cm at 45 degrees from the x axis to the vector 8.5 cm 105 degrees from the x axis.

Magnitude 17.85 cm

Angle: 69.36 degrees

Explanation:

Analytical sum of vectors

We have the vector 1 with magnitude 12 cm and angle 45 degrees. We'll find its cartesian components by using

Now we find the components of v2

To add both vectors, we add their components separately

Magnitude of :

Angle of :

the average speed is 24.57 km/hr

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
