Answer:

Analog and digital signals are the types of signals carrying information. The major difference between both signals is that the analog signals have continuous electrical signals, while digital signals have non-continuous electrical signals.

Explanation:

Analog Signals were used in many systems to produce signals to carry information. These signals are continuous in both values and time. The use of analog signals has been declined with the arrival of digital signals. In short, to understand the analog signals – all signals that are natural or come naturally are analog signals. Digital Signals , unlike analog signals, digital signals are not continuous, but signals are discrete in value and time. These signals are represented by binary numbers and consist of different voltage values. Their differences are as follows:

Analog Signals Digital Signals

Continuous signals Discrete signals

Represented by sine waves Represented by square waves

The Human voice, natural sound, analog electronic devices are few examples Computers, optical drives, and other electronic devices

A Continuous range of values Discontinuous values

Records sound waves as they are Converts into a binary waveform.

Only be used in analog devices. Suited for digital electronics like computers, mobiles, and more.

I think a Digital signal is better.

irina1246 [14]

The proton and electron experience forces to the left and right of the page, the particles would separate to the left and right respectively after the magnetic field is applied.

To know what would happen to each particle when a magnetic field pointing in the direction of the page is applied, we need to know the direction of the force acting on the particles due to this magnetic field according to fleming's left hand rule

<h3>What is Fleming's left hand rule?</h3>

This states that when the thumb, the middle-finger and fore-finger of the left-hand are held at right angles to each other, the magnetic field points in the direction of the fore-finger, the current (or direction of charge) points in the direction of the middle finger and the force on the conductor or charge points in the direction of the thumb.

<h3>What is the direction of force on the proton?</h3>

Since the direction of the proton is up the page and the direction of the magnetic field is into the page, the direction of the force according to fleming's left hand rule is to the left of the page.

<h3>What is the direction of force on the electron?</h3>

Since the direction of the electron is up the page (it is in the direction of the conventional current or positive charge in the other direction) and the direction of the magnetic field is into the page, the direction of the force according to fleming's left hand rule is to the right of the page.

Since both the proton and electron experience forces to the left and right of the page, the particles would separate to the left and right respectively after the magnetic field is applied.

You go to the hardware store to buy a new 50 ft garden hose. You find you can choose between hoses of ½ inch and 5/8 inch inner

omeli [17]

To solve this problem it is necessary to consider two concepts. The first of these is the flow rate that can be defined as the volumetric quantity that a channel travels in a given time. The flow rate can also be calculated from the Area and speed, that is,

Q = V*A

Where,

A= Cross-sectional Area

V = Velocity

The second concept related to the calculation of this problem is continuity, which is defined as the proportion that exists between the input channel and the output channel. It is understood as well as the geometric section of entry and exit, defined as,

$Q_1 = Q_2$

$V_1A_1=V_2A_2$

Our values are given as,

$A_1=\frac{1}{2}^2*\pi=0.785 in^2$

$A_2=\frac{5}{8}^2*\pi=1.227 in^2$

Re-arrange the equation to find the first ratio of rates we have:

$\frac{V_1}{V_2}=\frac{A_2}{A_1}$

$\frac{V_1}{V_2}=\frac{1.227}{0.785}$

$\frac{V_1}{V_2}=1.56$

The second ratio of rates is

$\frac{V2}{V1}=\frac{A_1}{A2}$

$\frac{V2}{V1}=\frac{0.785}{1.227}$

$\frac{V2}{V1}=0.640$

Lucy and her bike together have a mass of 120kg. She slows down from 4.5m/s to 3.5m/s. How much kinetic energy does she lose?

vovangra [49]

The kinetic energy of a moving object is given by
$K= \frac{1}{2}mv^2$
where m is the object's mass and v its velocity.

In our problem, the initial kinetic energy is:
$K_i = \frac{1}{2} m v_i^2 = \frac{1}{2}(120 kg) (4.5 m/s)^2=1215 J$

while the final kinetic energy is:
$K_f = \frac{1}{2}mv_f^2 = \frac{1}{2}(120 kg)(3.5 m/s)^2= 735 J$

So, the kinetic energy lost by Lucy and her bike is
$\Delta K = K_i - K_f = 1215 J - 735 J = 480 J$
