Answer:

The cable run exceeds the specifications for Ethernet over twisted pair

Explanation:

The ethernet network's router also serves as a bridge to the Internet. The router connects to the modem, which carries the Internet signal, sending and receiving data packet requests and routing them to the proper computers on the network.

Ethernet is a way of connecting computers together in a local area network or LAN. It has been the most widely used method of linking computers together in LAN s since the 1990 s.

The basic idea of its design is that multiple computers have access to it and can send data at any time.

The mass of the car should be A) 1212 kg

Explanation:

We can solve the problem by using Newton's second law of motion, which states that

$F=ma$

where:

F is the force produced by the engine

m is the mass of the car

a is its acceleration

In the first situation we have

m = 1515 kg

$a=12 m/s^2$ is the acceleration

Solving for F, we find the force produced by the engine:

$F=(1515)(12)=18,180 N$

Now we want the car to reach an acceleration of

$a'=15 m/s^2$

Using the same engine, therefore the force produced is still

F = 18,180 N

Re-arranging the equation for m', we find what should be the new mass of the car:

$F=m'a'\\m' = \frac{F}{a'}=\frac{18180}{15}=1212 kg$

An incident electromagnetic wave is polarized and its E vector has a maximum value of 6 Volts/m. It is incident on a polarizer w

adell [148]

To solve this problem it is necessary to apply the equations related to the law of Maus.

By the law of Maus we know that

$I = I_0 cos^2 \theta$

Where,

$I_0$ = Intesity of incident light

I = Intensity of polarized light

With our values we have that

$I_0 =$ 6V/m

$\theta = 45\°$

Then

$I = 6*cos^2(45)$

$I = 3V/m$

Therefore the maximum value of the transmitted E vector is 3V/m
