which of these are devices that let employees enter buildings and restricted areas and access secured computer systems at any time, day or night?

Thermoplastics become softer when heated and firmer when they cool. however when they are heated, thermosetting polymers become harder.

a. The thermoset polymer can only be heated once; once heated, it cannot be reheated to allow for further molding. This polymer becomes stronger when heated. The chemical composition of thermoplastic polymers, on the other hand, is unaffected by repeated heating and remolding.

b. In contrast to thermoplastic polymers, which have a linear and flexible structure that allows for molding and reheating, thermoset polymers have strong covalent cross connections in their molecular structure.

The main distinction between the two is that thermoset, a material that becomes stronger when heated, cannot be remolded or heated once it has been formed, whereas thermoplastics may be warmed, remolded, and cooled as needed without resulting in any chemical changes.

The amount of open-loop phase change required to cause an unstable closed-loop system is known as the phase margin.

Phase crossover occurs at 0.010 Hz, hence the gain margin is 1.00/0.45=2.22 at that frequency. The amount of degrees that the phase angle at the gain crossover is less than 180° is known as the phase margin.

When an input change, like as a step function, is applied, phase margin reflects relative stability, or the propensity to oscillate during that response. Gain margin shows utmost stability and how much the system will swing unrestrainedly in the presence of any disruption.

When G(jw)|=1, the phase of G(jw) is greater than -180deg, which is referred to as a positive phase margin. The system's level of stability can be determined in this way. In terms of stability, a wider phase margin is preferable. System instability is indicated by a negative phase margin.

The number of teeth on the output gear is 27, the radius of the output gear is 1.687 in, the radius of the pinion gear is 2.25 in.

TR = torque ratio = 0.75

Np = number of teeth on pinion gear = 36

P = diametral pitch = 8

Since only number of teeth on pinion gear is known, we calculate the radius of pinion gear first using this equation,

diameter of pinion gear (dp) = Np / P

= 36 / 8

= 4.5 in

Radius is half of diameter so the radius of pinion gear is 4.5 / 2 = 2.25 in

Then, we calculate the radius for output gear using this equation,

radius of output gear = TR * radius of pinion gear

= 0.75 * 2.25

= 1.6875 in

Next, we calculate number of teeth on output gear using this equation,

number of teeth on output gear = TR * Np

= 0.75 * 36

= 27

Thus, the output gear have 27 teeth with radius 1.6875 in and the pinion gear have radius 2.25 in.

Xor, and, or, not is called as binary operation. Binary operation is operation to combine two binary number to produce another number.

To know the incorrect options we will evaluate each option,

For xor al, 0

The program is to xor-ing each value of al by 0. Xor result will be 1 if only single 1 in set. i.e.

0 xor 0 = 0

0 xor 1 = 1

1 xor 0 = 1

1 xor 1 = 0

So, this operation will keep the highest bit, and set the SF accordingly.

For or al, 0

The program is to or-ing each value of al by 0. Or result will be 1 except if both input is 0. i.e.

0 or 0 = 0

0 or 1 = 1

1 or 0 = 1

1 or 1 = 1

So, this operation will keep the highest bit, and set the SF accordingly.

For and al, al

The program is to and-ing each value of al by itself. And result will be 1 if only both input is 1. i.e.

0 or 0 = 0

0 or 1 = 0

1 or 0 = 0

1 or 1 = 1

So, this operation will keep the highest bit, and set the SF accordingly.

For not al

The program is to not-ing each value of al. Not result will be flipping the value. i.e.

not 0 = 1

not 1 = 0

So, this operation will flip the highest bit, and set the SF wrongly.

Since SSB modulation calls for a precise frequency response from the filter, only one sideband must be transmitted entirely.
