Vector b has x, y, and z components of 2.2, 6.6, and 5.5 units, respectively.
calculate the magnitude of b.

8.9 units

Explanation:

The magnitude of a 3-D vector B can be calculated by using the formula:

where are the x, y and z components of the vector, respectively.

For the vector in the problem:

Substituting into the equation, we find the magnitude of B:

So, the magnitude of B is 8.9 units.

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.
