P abs = P g + P atm where P atm is the pressure in the atmosphere, Pg is the pressure in a gauge, and P abs is the pressure in absolute terms. While gauge pressures (PG) are established using reservoir pressures, you must also choose the atmospheric pressure (P atm) because these pressures are absolute: P abs = P atm + PG.

Orbital speed is influenced by the mass of the central body (Earth), the orbital radius, and the equation v = SQRT(G * Mcentral / R). The height of the satellite above the earth determines the orbital radius in turn.

The position of body m2 in relation to m1 is determined by the actual anomaly using the orbit formula, r = (h2/)/(1 + e cos ). We must be able to calculate the location of m2 as a function of time for a variety of practical reasons.

We can use the following equations to determine the variables associated with the spacecraft's orbit:

(a) The semi-major axis, a:

a = (r_p + r_a) / 2

(b) The eccentricity, e:

e = (r_a - r_p) / (r_a + r_p)

(c) The semi-latus rectum, p:

p = h^2 / μ

(d) The magnitude of the specific angular momentum, h:

h = r v

(e) The speed of the spacecraft at periapsis and apoapsis, v_p and v_a:

v_p = sqrt(μ (2 / r_p - 1 / a))

v_a = sqrt(μ (2 / r_a - 1 / a))

where:

r_p = radius of periapsis

r_a = radius of apoapsis

h = specific angular momentum

v = velocity

Using the given values, we have:

r_p = R_e + 500 km = 6878.145 km

r_a = R_e + 800 km = 7178.145 km

(a) The semi-major axis:

a = (r_p + r_a) / 2 = (6878.145 + 7178.145) / 2 = 7028.145 km

(b) The eccentricity:

e = (r_a - r_p) / (r_a + r_p) = (7178.145 - 6878.145) / (7178.145 + 6878.145) = 0.1427

(c) The semi-latus rectum:

p = h² / μ = r v² / μ = a (1 - e²) = 6078.144 km

(d) The specific angular momentum's size:

h = r v = sqrt(μ p) = 3.2943e+04 km²/s

(e) The spacecraft's speed during apoapsis and periapsis:

v_p = sqrt(μ (2 / r_p - 1 / a)) = 7.619 km/s

v_a = sqrt(μ (2 / r_a - 1 / a)) = 6.288 km/s

We apply the equation Eq = MW / n to determine the Gram Equivalent Weight. Here, we'll discover how to determine a compound's equivalent weight formula. If a chemical entity has a mass of g grammes, then the mass supplied contains the gramme equivalents determined by the valency factor moles.

We can utilise the approach of connecting resistors in series and parallel to determine the equivalent resistance of the resistive network. We can connect the two resistors in parallel starting from the circuit's right side:

1/Rp = 1/80k + 1/80k

1/Rp = 1/40k

Rp = 40k Ohms

Next, we can connect the 80k resistor and 40k resistor in series:

R = 80k + 40k

R = 120k Ohms

Linear search and binary search are two algorithms used to find a target value in a sorted list.

Linear search is a simple but inefficient algorithm that can be used on unsorted or small lists, while binary search is a more complex but efficient algorithm that requires a sorted list and is best suited for large lists.

According to question:

(A). The advantage of using a binary search over a linear search increase as the size of the list increases.

That's true. A linear search algorithm goes through each item in the list one by one until it either discovers the desired value or runs out of items to verify. In the worst situation, the algorithm must examine each element because the target value is the last item on the list. This indicates that a linear search has an O time complexity (n).

A binary search algorithm, on the other hand, continually splits the search period in half until it locates the desired value. This indicates that a binary search has an O time complexity (log n). The speed gap between linear and binary search becomes more pronounced as the size of the list grows.

(B).  The program can also be expressed as binary code but will be more easily understood by humans when expressed in a higher-level programming language.

Although this assertion is true, it has little to do with whether to do a linear or binary search. Programs can be expressed as binary code, but this low-level form is difficult for humans to read or alter. Programmers find it simpler to read and create code in higher-level programming languages because they offer more abstraction and a syntax that is more like to natural language. The performance of the program could be impacted by the search algorithm selection, but the readability of the code is unaffected.

Absolute pressure = gauge pressure + atmospheric pressure

Gauge pressure = specific gravity x density of water x depth

Density of water = 1000 kg/m^3 for fresh water, 1030 kg/m^3 for seawater

Using these equations, the gauge pressure exerted on the diver 20 m below the surface of the sea is:

Gauge pressure = 1.03 x 1030 kg/m^3 x 20 m x 9.81 m/s^2 = 203 kPa

Adding this to the atmospheric pressure of 100 kPa, the absolute pressure exerted on the diver is:

Absolute pressure = 203 kPa + 100 kPa = 303 kPa

What is the formula for calculating absolute pressure?

The formula for calculating absolute pressure is Pabsolute = Pgauge + Patm, where Pabsolute is the total pressure acting on an object, Pgauge is the pressure measured by a gauge or instrument, and Patm is the atmospheric pressure at the location. In other words, absolute pressure is the sum of gauge pressure and atmospheric pressure.

This outcome is compatible with the lambda-parameterized Poisson distribution's Mw formula.

To compare different quantities of the same category, averages are utilised. For instance, because there are disparities in the salaries of multiple employees, averages must be used to calculate the per-employee salary of a firm.

(a) The Poisson distribution can be used to determine the probability function P(x) as a function of the degree of polymerization x:

P(x) = (lambda^x / x!) * exp(-lambda)

where lambda = -ln(1 - 0.985) = 4.199 is the average number of reactive functional groups per polymer chain. The probability of finding a chain with DP = x is proportional to P(x). The plot of P(x) as a function of x is shown below:

P(x) plot

(b) The weighing function w(x) for calculating Mw can be calculated as follows:

w(x) = x * P(x) / sum{k * P(k), k=0 to infinity}

where P(x) is the probability function calculated in part (a). The weighing function w(x) represents the contribution of chains with DP = x to the Mw calculation. The plot of w(x) as a function of x is shown below:

w(x) plot

(c) The number-average molecular weight Mn can be calculated by integrating over the DP distribution:

Mn = sum{k * w(k), k=0 to infinity}

We can approximate the sum as an integral:

Mn = integral{k * w(k) dk, k=0 to infinity}

Substituting w(x) from part (b), we get:

Mn = integral{x * P(x) dx / sum{k * P(k), k=0 to infinity}, x=0 to infinity}

sum{k * P(k), k=0 to infinity} = exp(lambda) = exp(-ln(1 - 0.985)) = 21.832

Substituting this value, we get:

Mn = integral{x * P(x) dx / 21.832, x=0 to infinity}

Performing the integration, we get:

Mn = lambda / (1 - exp(-lambda)) = 4.407

(d) The weight-averaged molecular weight Mw can be calculated by integrating over the DP distribution weighted by the number of polymer chains with that DP:

Mw = sum{M(x) * w(x), x=0 to infinity}

We can approximate the sum as an integral:

Mw = integral{M(x) * w(x) dx, x=0 to infinity}

Substituting M(x) = x * Mn, we get:

Mw = Mn * integral{x^2 * P(x) dx / sum{k * P(k), k=0 to infinity}, x=0 to infinity}

Substituting w(x) from part (b), we get:

Mw = Mn * integral{x^2 * P(x) dx / sum{k * x * P(k), k=0 to infinity}, x=0 to infinity}

sum{k * x * P(k), k=0 to infinity} = lambda^2

Substituting this value, we get:

Mw = Mn * integral{x^2 * P(x) dx / lambda^2, x=0 to infinity}

Mw = Mn * (1 + lambda) / (1 - exp(-lambda)) = 13.863
