Yes, yes, we know all of that. It certainly took you long enough to
get around to asking your question.
If
a = (14, 10.5, 0)
and
b = (4.62, 9.45, 0) ,
then, to begin with, neither vector has a z-component, and they
both lie in the x-y plane.
Their dot-product a · b = (14 x 4.62) + (10.5 x 9.45) =
(64.68) + (99.225) = 163.905 (scalar)
I feel I earned your generous 5 points just reading your treatise and
finding your question (in the last line). I shall cherish every one of them.
D
Because the rest of the answers are illogical
Answer:
D. Freezing?
Explanation:
Get water, put it in the freezer, turns into ice after a few hours.
Answer:
The current in the wire is 31.96 A.
Explanation:
The current in the wire can be calculated as follows:

<u>Where</u>:
q: is the electric charge transferred through the surface
t: is the time
The charge, q, is:

<u>Where</u>:
n: is the number of electrons = 7.93x10²⁰
e: is the electron's charge = 1.6x10⁻¹⁹ C

Hence, the current in the wire is:

Therefore, the current in the wire is 31.96 A.
I hope it helps you!
