Answer:

A turbo blade has the best features from both other types of blade. The continuous, serrated edge makes for fast cutting while remaining smooth and clean. They are mostly used to cut a variety of materials, such as tile, stone, marble, granite, masonry, and many other building materials.

What are some advantages of the nano ceramic coating for cars with explication

ad-work [718]

Answer:

Ceramic coating offers good protection to the car's surface. The nano-coating can protect the car from most scratches, dirt and chemical contaminants. Ceramic coating also doesn't have any side-effects to the original paint. Ceramic coating also lasts longer than regular paint.

The output S/N at thereceiver must be greater than 40 dB. The audio signal has zero mean, maximum amplitude of 1, power of ½ Wan

abruzzese [7]

Given that,

The output signal at the receiver must be greater than 40 dB.

Maximum amplitude = 1

Bandwidth = 15 kHz

The power spectral density of white noise is

$\dfrac{N}{2}=10^{-10}\ W/Hz$

Power loss in channel= 50 dB

Suppose, Using DSB modulation

We need to calculate the power required

Using formula of power

$P_{L}_{dB}=10\log(P_{L})$

Put the value into the formula

$50=10\log(P_{L})$

$P_{L}=10^{5}\ W$

For DSB modulation,

Figure of merit = 1

We need to calculate the input signal

Using formula of FOM

$FOM=\dfrac{\dfrac{S_{o}}{N_{o}}}{\dfrac{S_{i}}{N_{i}}}$

$1=\dfrac{\dfrac{S_{o}}{N_{o}}}{\dfrac{S_{i}}{N_{i}}}$

$\dfrac{S_{i}}{N_{i}W}=\dfrac{S_{o}}{N_{o}}$

Put the value into the formula

$\dfrac{S_{i}}{2\times10^{-10}\times15\times10^{3}}$

$\dfrac{S_{i}}{30\times10^{-7}}$

$S_{i}$

$S_{i}=30\times10^{-3}$

We need to calculate the transmit power

Using formula of power transmit

$S_{i}=\dfrac{P_{t}}{P_{L}}$

$P_{t}=S_{i}\times P_{L}$

Put the value into the formula

$P_{t}=30\times10^{-3}\times10^{5}$

$P_{t}=3\ kW$

We need to calculate the needed bandwidth

Using formula of bandwidth for DSB modulation

$bandwidth=2W$

Put the value into the formula

$bandwidth =2\times15$

$bandwidth = 30\ kHz$

Hence, The transmit power is 3 kW.

The needed bandwidth is 30 kHz.

Please help me

Minchanka [31]

Answer:

The first step of the problem solving process is to identify and define the problem. The second step, which is to analyze the problem, involves gathering information, sorting through relevant and irrelevant information, and evaluating the source of the problem by asking the Five W's: who, what, where, when, and why.

A box of mass m = 4 kg is suspended vertically from a spring with stiffness k = 64 N/m. Determine the position of the box as a f

Hatshy [7]

Answer:

x=0.5 sin 4 t

Explanation:

Given that:

mass m = 4 kg

Stiffness K =64 N/m

Given spring mass system will be in simple harmonic motion.We know that in simple harmonic motion the natural frequency given as follows

$\omega _n=\sqrt{\dfrac{K}{m}}$

Now by putting the values

$\omega _n=\sqrt{\dfrac{64}{4}}$

$\omega _n=4 rad/s$

The equation of SHM given as

$\ddot{x}+\omega _n^2x=0$

The solution of above equation will be

$x=Asin\omega _nt$

x=A sin 4 t

Given at t=0 ,V= 2 m/s

V= 4 A cos 4 t

2 = 4 A

A= 0.5

The equation of motion will be

x=0.5 sin 4 t

Which statement about direct-mail messages is most accurate? Group of answer choices Direct mail is an effective channel for per

torisob [31]

Answer:

Option A

Direct mail is an effective channel for personalized, tangible, three-dimensional messages that are less invasive than telephone solicitations

Explanation:

In modern days, we've seen email marketing hence option B that "Today's companies no longer send direct-mail messages to market their products or services; they rely exclusively on electronic media instead." These companies rely also on direct mails to their clients. Online marketing often uses direct mail for persuasion of their customers hence the last option is also wrong. Considering that already two statements are identified as inaccurate, the option that "All answer choices are accurate statements about direct-mail messages. " is misleading. Therefore, the only most accurate choice about direct-mail is option A
