Vector b~ has x, y, and z components of 9.2, 4.8, and 6.3 units, respectively.

12.1 units

Explanation:

The problem is asking to find the magnitude of B.

The magnitude of a 3-D vector is given by:

where

x, y and z are the components of the vector along the x, y and z directions, respectively

For vector B in this problem,

x = 9.2

y = 4.8

z = 6.3

Therefore, its magnitude is:

an obstruction

a sonic boom is a loud boom that breaks the sound barrier
