Consider a vector 4.08 + 3.0 , wherex, are the unit vectors in x-, y-directions, respectively. (a) what is the magnitude of the vector a? (b) what are the angles vector a makes with the x and y axes, respectively?

Part a)

Magnitude = 5.06 unit

Part b)

Explanation:

Part a)

Vector is given as

now from above we can say that

x component of the vector is 4.08

y component of the vector is given as 3.0

so the magnitude of the vector is given as

Part b)

Now the angle made by the vector is given as

for i will definitly keep him in my prayers. may god bles you and your

plz mark me as brainliest

have an amazing day

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!
