Answer:

"It is made of numbers" describes the digital signal.

Explanation:

The digital signal are the electrical signal which is translated into the pattern of bits. The digital signal are always discrete value in every sampling point. The conversion of the programming into the stream or the binary sequence like 0s and 1s. The digital signals never gets weaken over distance but the analog signal gets weakened or impair at distance. The digital signals are consists of one or two value, Timing graph are square waves.

What is the frequency of an ocean wave that is traveling at a speed of 45 m/s if it has a wavelength of 3 meters.

V125BC [204]

Answer:

The frequency of an ocean wave is 15 Hz.

Explanation:

We are given with, the speed of an ocean wave is 45 m/s. Its wavelength is 3 m

It is required to find the frequency of an ocean wave.

The speed of a wave is given in terms of frequency and wavelength as :

$v=f\lambda$ ,

f = frequency of ocean wave

$f=\dfrac{v}{\lambda}\\\\f=\dfrac{45}{3}\\\\f=15\ Hz$

So, the frequency of an ocean wave is 15 Hz.

In unit-vector notation, what is the net torque about the origin on a flea located at coordinates (-2.0, 4.0 m, -1.0 m) when for

kifflom [539]

Answer:

Torque, $\tau=-21i-8j+10k$

Explanation:

Given that,

Coordinates, $r=(-2i+4j-k)\ m$

Force acting on the flea, $F=(0i-5j-4k)\ N$

Let $\tau$ is the net torque about the origin on a flea. It is given by the following formula :

$\tau=r\times F$

$\tau=(-2i+4j-k)\times (0i-5j-4k)$

$\tau=\begin{pmatrix}-21&-8&10\end{pmatrix}$

$\tau=-21i-8j+10k$

So, the net torque about the origin on a flea is $-21i-8j+10k$ . Hence, this is the required solution.

What is the voltage drop across the 10.0 ohm resistor?

DochEvi [55]

The voltage across all the resistors is the same i.e 120V

Each element of the parallel circuit has the same voltage applied to it. The total current flowing from the source is equal to the sum of the currents across each path. The electric potential difference (V) across each resistor in a parallel circuit is the same. Ohm's law states that I = V / R applies to the current in a resistor. The current will be lowest where the resistance is highest since the V is the same for each resistor. The currents passing through each resistor in a parallel combination have the same voltage across them because of their different resistance values and the laws of Ohms i., If two or more components are connected in parallel, they will be having same difference of potential (voltage) across their ends Parallel circuits are then used as current dividers.
