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.

A particle of charge +13 µC and mass 3.57 10-5 kg is released from rest in a region where there is a constant electric field of
DerKrebs [107]

Answer:

20.3 mm

Explanation:

The force  on the charge F = qE where q = charge = +13 µC = +13 × 10⁻⁶ C and E = electric field intensity = +495 N/C.

The acceleration of the charge is thus a = F/m where m = mass of charge = 3.57 × 10⁻⁵ kg.

Its displacement is gotten from

s = ut + at²/2  where u = initial speed = 0 (since the charge starts from rest) and t = 1.5 × 10⁻² s.

s = 0 +at²/2 = at²/2

Substituting a and t into s we have

s = qEt²/2m = +13 × 10⁻⁶ C × +495 N/C × (1.5 × 10⁻² s)²/(2 × 3.57 × 10⁻⁵ kg) = 0.0203 m = 20.3 mm

A 105 kg crate initially at rest on a horizontal floor requires a 705 N horizontal force
DENIUS [597]

Answer:

μs = 0.68

μk = 0.577

Explanation:

In order to solve this problem, we must remember that the normal force on a body that rests on a horizontal surface is equal to the weight of a body but in the opposite direction.

W=N\\N=m*g\\N=105*9.81\\N=1030.05[N]

The friction force is defined as the product of the coefficient of friction by the normal force.

Now when the body is in motion we have that the coefficient of friction is the dynamic one.

595 = μk*N

μk = 595/1030.05

μk = 0.577

Now to start moving it requires a force of 705 [N].

705 = μs*N

μs = 705/1030.05

μs = 0.68
