There are six wires which need to be attached to a circuit
board. A robotic device will attach the wires. The wires can be
attached in any order, and the production manager wishes to
determine which order would be fastest for the robot to use. Use
the multiplication rule of counting to determine the number of
possible sequences of assembly that must be tested. (Hint:
There are six choices for the first wire, five for the second wire,
four for the third wire, etc. Enter an exact number.)
Compute C5,3. (Enter an exact
number.)
Solutions
Expert Solution
Number of possible sequences = 6 * 5 * 4 * 3 * 2 * 1 = 720
5C3 = 5! / (3! * (5 - 3)!) = 10

A long pair of isolated wires provides a device with 12.5A
direct current as input / output. If the diameters of the wires are
negligible, but if there is a 2.8mm gap with each other, calculate
the magnitude of the magnetic field at a distance of 10cm from the
middle point of this gap and compare it with the magnetic field of
the world and discuss your result.

A basic electrical circuit consists of a battery, a light bulb,
a switch and wires connecting them. As soon as the switch is
closed, even the light bulb is one mile away, the light bulb will
be on IMMEDIATELY. This means that the electrical
current (made of moving electrons) starts to run everywhere in the
wire as soon as the switch is closed.
Explain:
a) the origin of these free moving electrons (where do they come
from),
b) the force(s) that...

(Please just show the design of the circuit)
A printed circuit board manufacturing laboratory needs to have controlled environmental conditions, such as temperature, pressure, and humidity. These variables are measured by means of sensors that deliver an electrical signal which must be conditioned before being sent to a microcontroller for processing.
The challenge is to perform signal conditioning with pressure sensor op amps with part number MPX4250. The conditions that this signal conditioning must meet are the following:
