Explanation:

The heat flux is =1038kW/m² , the heat lost per hour is =259.5 kW, the heat lost per hour using a sheet of soda- lime glass.

The thickness of steel( t) = 10mm = 10× 10^-³m

The temperature difference on both sides = 300-100

∆T = 200°C

But the formula for heat flux = q = k∆T/t

Where K = thermal conductivity for steel = 51.9W/mK.

Substitute the variables into the formula for heat flux;

q = 51.9 × 200/10 × 10-³

q = 10380 × 10³/10

q = 10380000/10

q = 1038000 W/m² = 1038kW/m²

To calculate the heat lost per hour if the cross sectional area is = 0.25 m2 use the formula q × A

= 1038kW/m² × 0.25 m2

= 259.5 kW.

You get a result immediately from Euler's formula:

e ^(i π/2) = cos(π/2) + i sin(π/2) = 0 + i * 1 = i

Fermat's theorem can be used to find a number x between 0 and 28 that satisfies the congruence x^85 ≡ 6 (mod 29). By applying the theorem, we can simplify the calculation and determine the value of x without resorting to brute-force searching.

Fermat's theorem states that if p is a prime number and a is an integer not divisible by p, then a^(p-1) ≡ 1 (mod p). In this case, the prime number is 29. We can rewrite the congruence x^85 ≡ 6 (mod 29) as x^(283+1) ≡ 6 (mod 29), which implies that x^(283) * x ≡ 6 (mod 29).

Using Fermat's theorem, we know that x^(28*3) ≡ 1 (mod 29), since 29 is a prime number. Therefore, the congruence simplifies to 1 * x ≡ 6 (mod 29), which gives us x ≡ 6 (mod 29).

To find the value of x within the range of 0 to 28, we can observe that 6 + 29 = 35 is a multiple of 29. Thus, x = 35 satisfies the congruence. However, since we are looking for a value between 0 and 28, we subtract multiples of 29 from 35 until we find a value within the desired range. In this case, 35 - 29 = 6, so x = 6 is the solution that satisfies x^85 ≡ 6 (mod 29) within the given constraints.

Answer: observational error

Explanation:

An Error occurs when the measurement is actually done by the Observational approach. Thus, the correct option is D.

The ideal methods of measurement are subdivided into two methods: They are as follows:

The Direct measurement method involves the utilization of instruments such as micrometers, vernier calipers, coordinate measuring machines, etc. In this method, the unknown quantity is directly compared with the standard quantity.

In the Indirect measurement method, the physical parameter of the quantity is measured with the help of the direct method.

Positioning of the required quantity, operator-biased measurement, and the utilization of instruments for estimating the measurement of any unknown value are generally favored in order to eliminate the chances of errors.

The best description of the bonding in a3b is option a. the AB bond is largely ionic with a - on A.This statement accurately captures the nature of the bonding, indicating that element a (A) has a partial negative charge (-) due to the transfer of electron(s) to element b.

The bonding in a3b is largely ionic is suggested by the fact that electronegativity difference between element a (0.8) and element b (3.0) is 2.2, which indicates a significant difference in their ability to attract electrons.

In an ionic bond, one atom (in this case, element b) has a higher electronegativity and tends to attract electrons more strongly than the other atom (element a). As a result, element b will acquire a partial negative charge, indicated by the presence of electron(s) in its outer shell, while element a will have a partial positive charge.

Since element b has a higher electronegativity, it can effectively pull the shared electrons towards itself, resulting in a partial negative charge. On the other hand, element a, with a lower electronegativity, will have a partial positive charge as it loses electron(s) to element b.

Therefore, the best description of the bonding in a3b is a. The AB bond is largely ionic with a - on A.

rotation around the center axis

Angular acceleration = torque + MOI

Currently, angular acceleration equals 2 rpm/(t 60).

In order to avoid getting an extremely high figure, we estimated that the diameter of the cylinder was 600 mm rather than 600 meters: angular acceleration= 1.047 rad/s² MOI for cylinder across center dia= 1/4MR²+ 1/12ML²

Erik Erikson's psychosocial theory suggests that studying relationships, including friendships and romantic partnerships, is crucial for understanding socioemotional development in early adulthood.

One theoretical perspective that emphasizes the study of

socioemotional development in early adulthood, particularly in the context of relationships, is Erik Erikson's psychosocial theory.

Erikson proposed a series of psychosocial stages that individuals progress through across their lifespan, and one of the key stages relevant to early adulthood is the stage of intimacy versus isolation.

According to Erikson, the primary task during early adulthood is to develop intimate relationships with others while maintaining a sense of identity.

During this stage, individuals seek close and meaningful connections with friends, romantic partners, and potentially even long-term commitments such as marriage or starting a family.

It is through these relationships that individuals can experience companionship, love, and emotional intimacy.

Erikson argued that successfully navigating this stage leads to the development of a capacity for intimacy, which involves the ability to form deep and meaningful connections with others.

However, if individuals struggle to form these relationships or experience significant feelings of isolation and loneliness, they may face difficulties in establishing healthy relationships and may develop a sense of social isolation.

Thus, Erikson's psychosocial theory suggests that the study of relationships, whether they are friendships or romantic partnerships, is an appropriate focus for understanding socioemotional development in early adulthood.

By examining the formation of relationships and the factors that contribute to successful or unsuccessful relationship experiences, researchers can gain insights into how individuals develop social and emotional skills during this stage of life.

A.) When we create a balance on all these components

n1 + n2 + n3

n1 = n2 + 11.5

Creating a balance on hexane

n1y1C6H14 = n2y2C6H14 + n3y3C6H14

n1(0.18) = n2(0.05) + 11.5mol/min(1.00)

When we put the first equation into the second one:

(n2+11.5mol/min)0.18 + n2(0.05) + 11.5mol/min(1.00)

= 0.18n2 + 2.07min/mol = 0.5n2 + 11.5mol/min

Collect like terms

0.18n2 - 0.05n2 = 11.5 - 2.07min/mol

= 0.13n2 = 9.43

n2 = 9.43/0.13

n2 = 72.53 mol/min

72.53 is the flow rate of the gas stream leaving the burner.

B.) n1 = n2 + 11.5mol/min

n1 = 72.53mol/min + 11.5mol/min

n1 = 84.93mol/min

Amount of hexane entering condenser

n1c6H14 = y1C6H14 = 0.18(84.03mol/min)

= 15.1mol/min

The percentage condensed

= (11.5mol/min)/(15.1mol/min) * 100

= 76.2% of hexane is recovered as liquid

Answer:

minimum current level required =  8975.95 amperes

Explanation:

Given data:

diameter = 5.5 mm

length = 5.0 mm

T = 0.3

unit melting energy = 9.5 j/mm^3

electrical resistance = 140 micro ohms

thickness of each of the two sheets = 3.5mm

Determine the minimum current level required

first we calculate the volume of the weld nugget

v = \(\frac{\pi }{4} * D^2 * l\) = \(\frac{\pi }{4} * 5.5^2 * 5\) = 118.73 mm^3

next calculate the required melting energy

= volume of weld nugget * unit melting energy

= 118.73 * 9.5 = 1127.94 joules

next find the actual required electric energy

= required melting energy / efficiency

= 1127 .94 / ( 1/3 )  = 3383.84 J

TO DETERMINE THE CURRENT LEVEL REQUIRED  use the relation below

electrical energy =  I^2 * R * T

3383.84 / R*T = I^2

3383.84 / (( 140 * 10^-6 ) * 0.3 ) = I^2

therefore  8975.95 = I ( current )

(d) The system is linear, time-invariant, BIBO stable, has memory, is causal, and invertible with an inverse system y[n] = -x[n].

(a) For the system y(t) = (t^2 - 1)x(t - 1), we can see that it satisfies all the properties. It is linear because it exhibits the superposition property, meaning that if the input is scaled or added together, the output will also be scaled or added accordingly. It is time-invariant because the shift in the input results in a corresponding shift in the output. It is BIBO stable, meaning that for bounded inputs, the output remains bounded. It has memory as it depends on past and present values of the input. It is causal because the output does not depend on future values of the input. Finally, it is invertible, and its inverse can be found by reversing the operations, resulting in y(t) = x(t + 1).

(b) The system y[n] = e^(-x[n]) is linear because of the exponential function's properties. It is time-invariant as the shift in the input does not affect the output. It is BIBO stable since exponential functions are bounded. It has memory as it relies on past and present values of the input. It is causal because the output depends only on past and present values of the input. However, it is not invertible since the exponential function does not have a unique inverse.

(c) The system y(t) = 1 - x(t) is linear and time-invariant. It is BIBO stable as it involves simple algebraic operations. It has memory as it depends on past and present values of the input. It is causal because the output depends only on past and present values of the input. However, it is not invertible as the output does not uniquely determine the input.

(d) The system y[n] = ∑(n_0 to n) x[n] where n_0 is a fixed, finite time is linear, time-invariant, BIBO stable, has memory, and is causal. It satisfies all the properties. Moreover, it is invertible, and its inverse system can be represented as y[n] = -x[n-1], where the input is shifted one sample backward to obtain the inverse output.
