Question II: Write a program with a loop that repeatedly asks the user to enter a sentence. The user should enter nothing (press Enter without typing anything) to signal the end of the loop. Once the loop ends, the program should display the average length of the number of words entered, rounded to the nearest whole number.
Answers
The program prompts the user to enter sentences in a loop until they enter nothing. It then calculates and displays the average length of the words entered, rounded to the nearest whole number.
Here is an example program in Python that meets the requirements:
word_count = 0
total_length = 0
while True:
sentence = input("Enter a sentence (or press Enter to exit): ")
if sentence == "":
break
words = sentence.split()
word_count += len(words)
total_length += sum(len(word) for word in words)
average_length = round(total_length / word_count) if word_count > 0 else 0
print("Average word length:", average_length)
Explanation of code:
The program initializes two variables, word_count to keep track of the total number of words entered, and total_length to store the sum of the lengths of all the words.
The program enters a while loop that continues indefinitely until the user enters nothing (presses Enter without typing anything).
Inside the loop, the user is prompted to enter a sentence. If the sentence is empty, the loop is exited using the break statement.
If the user enters a sentence, it is split into individual words using the split() method.
The length of each word is calculated using a generator expression, and the total length is updated by adding the lengths of all the words.
The number of words entered is incremented by the length of the word list.
After the loop ends, the program calculates the average word length by dividing the total_length by the word_count, rounding it to the nearest whole number using the round() function. If no words were entered, the average length is set to 0.
Finally, the program displays the average word length to the user.
Note: This program assumes that words are separated by whitespace and does not consider punctuation or special characters as part of the words.

In a wheatstone bridge three out of four resistors have of 1K ohm each ,and the fourth resistor equals 1010 ohm. If the battery voltage is 100V,what is the approximate value of the open circuit voltage ? If the output of the bridge is connected to a 4 K ohm resistor, how much current would flow through the resistor?
Answers
Answer:
248.756 mV
49.7265 µA
Explanation:
The Thevenin equivalent source at one terminal of the bridge is ...
voltage: (100 V)(1000/(1000 +1000) = 50 V
impedance: 1000 || 1000 = (1000)(1000)/(1000 +1000) = 500 Ω
The Thevenin equivalent source at the other terminal of the bridge is ...
voltage = (100 V)(1010/(1000 +1010) = 100(101/201) ≈ 50 50/201 V
impedance: 1000 || 1010 = (1000)(1010)/(1000 +1010) = 502 98/201 Ω
__
The open-circuit voltage is the difference between these terminal voltages:
(50 50/201) -(50) = 50/201 V ≈ 0.248756 V . . . . open-circuit voltage
__
The current that would flow is given by the open-circuit voltage divided by the sum of the source resistance and the load resistance:
(50/201 V)/(500 +502 98/201 +4000) = 1/20110 A ≈ 49.7265 µA

Answers
The given problem states that the maintenance on a machine is expected to be $8257 for the second year and an additional $1,750 cost every year until year 6.
We are supposed to calculate the present equivalent value at the beginning of the first year if the interest is 4% per year.To calculate the present value of the maintenance, we will use the formula for the present value of an annuity, which is given by:PV = PMT [(1 - (1 + r)⁻ⁿ) / r]Here, PV is the present value, PMT is the payment, r is the interest rate per period, and n is the total number of periods.
To calculate the present value, we first need to calculate the total maintenance cost for years 2 to 6:Total maintenance cost for years 2 to 6 = $1,750 × 5= $8,750Now, we can calculate the present value of the maintenance cost using the formula:PV = $8257 + $8,750 / (1 + 0.04)² + $8,750 / (1 + 0.04)³ + $8,750 / (1 + 0.04)⁴ + $8,750 / (1 + 0.04)⁵PV = $31,092.06Therefore, the present equivalent value at the beginning of the first year if the interest is 4% per year is $31,092.06 (rounded to 2 decimal places).

A cylindrical tank is required to contain a gage pressure 560 kPa . The tank is to be made of A516 grade 60 steel with a maximum allowable normal stress of 150 MPa . If the inner diameter of the tank is 3 m , what is the minimum thickness, t, of the wall
Answers
Answer:
5.6 mm
Explanation:
Given that:
A cylindrical tank is required to contain a:
Gage Pressure P = 560 kPa
Allowable normal stress \(\sigma\) = 150 MPa = 150000 Kpa.
The inner diameter of the tank = 3 m
In a closed cylinder there exist both the circumferential stress and the longitudinal stress.
Circumferential stress \(\sigma = \dfrac{pd}{2t}\)
Making thickness t the subject; we have
\(t = \dfrac{pd}{2* \sigma}\)
\(t = \dfrac{560000*3}{2*150000000}\)
t = 0.0056 m
t = 5.6 mm
For longitudinal stress.
\(\sigma = \dfrac{pd}{4t}\)
\(t= \dfrac{pd}{4*\sigma }\)
\(t = \dfrac{560000*3}{4*150000000}\)
t = 0.0028 mm
t = 2.8 mm
From the above circumferential stress and longitudinal stress; the stress with the higher value will be considered ; which is circumferential stress and it's minimum value with the maximum thickness = 5.6 mm

Two gray bodies: Body 1 at 200oC and Body 2 at 100oC with emissivities of 0.6 and 0.8 respectively.
Required: The net heat transfer rate by radiation from Body 1 to Body 2 per m2, if: Bodies 1 and 2 are parallel disks each with 4 cm radius and 5 cm apart.
Answers
The net heat transfer rate by radiation from Body 1 to Body 2 per square meter is approximately 10.35 W/m^2.
The problem concerns the radiation heat transfer between two parallel disks. The disks have radii of 4 cm and emissivities of 0.6 and 0.8. They are maintained at temperatures of 200°C and 100°C respectively, with a distance of 5 cm between them. The objective is to determine the net heat transfer rate per square meter from Body 1 to Body 2, assuming no convective heat transfer occurs between the disks.
To calculate the heat transfer rate by radiation, the Stefan-Boltzmann law is applied:
q'' = σA1A2 (T1^4 - T2^4) / πD^2
Where:
q'' is the heat transfer rate by radiation
σ is the Stefan-Boltzmann constant (5.67 x 10^-8 W/m^2-K^4)
A1 and A2 are the areas of the two disks
T1 and T2 are the temperatures of the two disks
D is the distance between the two disks
From the equation, it is evident that the heat transfer rate by radiation is directly proportional to the area of the disks and the temperature difference between them, while inversely proportional to the square of the distance between them.
Calculating the area of each disk, A, we find A = πr^2 = 3.14 x 4^2 / 10000 = 0.000502 m^2.
Substituting the given values into the Stefan-Boltzmann law, we obtain:
q'' = 5.67 x 10^-8 x 0.000502 x 0.000502 x (473.15^4 - 373.15^4) / (π x 0.05^2)
≈ 10.35 W/m^2
Therefore, the net heat transfer rate by radiation from Body 1 to Body 2 per square meter is approximately 10.35 W/m^2.

Answers
Answer:
t₁ = 378.668 K
Explanation:
From the given information:
The heat dissipated (q) from the electrical device = \(10^4 W/m^2\)
The contact resistance between device and aluminium;
(R_{const} ) = 0.5× 10⁻⁴ m² K/W
Conductivity of aluminum (k) = 238 \ W/mK
The thickness of aluminum plate (L) = 0.004 m
Convection coefficient (h) = 100 \ W/m^2 K
Surrounding temperature (t_2) = 278 \ k
According to Fourier's law of heat conduction.
\(q = \dfrac { t_1- t_2 }{R_{const} + \dfrac{L}{k} + \dfrac{1}{h} }\)
\(10^4 = \dfrac{t_1 - 278}{0.5 \times 10^{-4} + \dfrac{0.004}{238} + \dfrac{1}{100} }\)
\(10^4 *( 0.5 \times 10^{-4} + \dfrac{0.004}{238} + \dfrac{1}{100}) = t_1 - 278\)
\(100.668 = t_1 -278\)

A. Synthetic provides maximum protection in extreme hot and cold temperature conditions.
B. Synthetic has greater resistance to oll thickening to maintain engine efficiency.
C. Synthetic Improves engine protection by resisting oil breakdown.
Answers
Answer:
1. All engines exhibit wear over time ⇒ Synthetic Improves engine protection by resisting oil breakdown.
Synthetic oil does not breakdown so easily which means that it protects the engine more and protects it from wearing.
2. Engines are cold at start-up and not while running ⇒ Synthetic provides maximum protection in extreme hot and cold temperature conditions.
By providing protection for the engine during cold and hot conditions, the engine will not be too cold when the car is started up.
3. If oil is thicker, engines lose power and efficiency ⇒ Synthetic has greater resistance to oil thickening to maintain engine efficiency.
Part of the characteristics of synthetic oil is that it does not get as thick as regular oil which means that the adverse effects of thick oil are spared on the engine.
