If A=3i +2j+3k ,find the magnitude of A+B and A-B

Since vector B was not specified, I'll assume one at random. You can later answer your own question.

Explanation:

Given:

And (assumed):

Find the magnitude of

Given a vector

The magnitude of the vector is:

The magnitude of the sum is:

The magnitude of the difference is:

i believe it is b. what was the cause of the big bang

hope this !

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
