Select the correct statement(s) regarding frequency modulation (FM). a. baseband amplitude changes (information) are captured as

mario62 [17]

<h3>All of the above statement are correct statement.</h3>

<u>Explanation</u>

Base-Band amplitude changes are captured as carrier wave wave frequency changes. In order to convert signal amplitude changes to changes in frequency, we need a device like VCO.

The bandwidth in the frequency domain increases with the change in carrier frequency.

A unidirectional E-Glass fiber-epoxy composite material contains 61% by volume E-Glass fibers stressed under isostrain condition

zalisa [80]

Answer:

The total load carried by the fiber will be "98%".

Explanation:

The given values are:

$V_{f}=0.61$

$V_{m}=1-V_{f}$

$=1-0.61$

$=0.39$

$E_{f}=10 \ Mpa$

$\sigma_{f}=0.35 \ Mpa$

$E_{m}=0.45 \ Mpa$ , $\sigma_{m}=9\times 10^{-3} \ Mpa$

As we know,

⇒ $E_{e}=fE_{f}+mE_{m}$

On putting the estimated values, we get

⇒ $=0.61\times 10+0.39\times 0.95$

⇒ $=6.27 \ Mpa$

Now,

⇒ $\sigma_{c}=f\sigma_{f}+m\sigma_{m}$

On putting the estimated values, we get

⇒ $=0.61\times 0.35+0.39\times 0.009$

⇒ $=0.217 \ Mpa$

Therefore,

The load carried by fiber,

$=\frac{f\sigma_{f}}{\sigma_{c}}$

$=\frac{0.35\times 0.61}{0.217}$

$=0.98$ i.e., 98%

Discuss how, as a safety professional, you would respond to the overlap in Occupational Safety and Health Administration (OSHA)

katrin2010 [14]

Answer:

Explanation:

As a security professional, I will respond positively to the OSHA requirements overlap. OSHA guidelines are meant to provide general guidance to all members of various entities throughout the country, while local or state codes also ensure compliance with laws unique to their areas, taking into account workplace safety and security.

OSHA accepts the security codes of the state building To the degree that such codes comply with OSHA regulations, such as BOCA. All the codes and regulations for local, state-owned construction, electrical and life protection are under the same umbrella. Generally, all security protocols and specifications are in accordance with OSHA guidelines. Nonetheless, certain points will overlap, while localized codes will also be addressed to a particular community or state that may

4. Which of the following are used for vehicle and/or major component identification?

AleksAgata [21]

Option C

VIN (vehicle identification number) are used for vehicle and/or major component identification

<h3><u>Explanation:</u></h3>

American automobile producers have practiced a vehicle identification number (V.I.N.) to name and recognize motor vehicles. They serve to retain an indication of obstacles, ownership exchanges, and prevent crime. This practice also posted the superimposed major component parts and replacement parts to be noted for each of the classes of vehicles.

Depending on the transport major parts may be marked with the vehicle’s VIN. The component part labels are composed of the alike material as the Federal Safety Certification Labels and are also planned to self destruct if excluded.
