Using a comparator, BCD/7-seg decoder, and 7-seg display to design a logic circuit which appears 9 (25 Marks) when A>B, 5 when A
Answers
Design a logic circuit using a comparator, BCD/7-seg decoder, and 7-seg display to display the number 9 when A > B, 5 when A = B, and 1 when A < B.
To design a logic circuit that displays different numbers based on the comparison of A and B, we can use a comparator, a BCD/7-segment decoder, and a 7-segment display.
First, the comparator compares the values of A and B. When A is greater than B, the comparator outputs a logic high signal (1). When A equals B, the comparator outputs a logic low signal (0), and when A is less than B, the comparator outputs a negative voltage.
Next, the output of the comparator is connected to the input of the BCD/7-segment decoder. The BCD/7-segment decoder receives the comparator's output and translates it into the corresponding BCD (Binary-Coded Decimal) code. In our case, we need to display the number 9 when A > B, 5 when A = B, and 1 when A < B.
Finally, the BCD code from the decoder is connected to the 7-segment display. The 7-segment display receives the BCD code and activates the appropriate segments to display the desired number. By configuring the BCD/7-segment decoder accordingly, the logic circuit will display the number 9, 5, or 1 based on the comparison of A and B.

Diagram shows a boy pulling a crate with diffrent length of the identical rope with the same force. He felt it was easier to pull the crate by using the longer rope. Explain why? [4 marks)
Answers
Explanation:
Work is mathematically expressed as force×distance(ie:the force applied to an item to move it × the distance both the force & the item moved through)
This means an increase in force or distance while doing work will increase the intensity of the work being done,which implies that the work will be done easier & faster.
Therefore,he felt it was easier while pulling the crate with the longer rope due to its increased length or distance.

how fast do you have to slap a chicken to cook it
Answers
Slapping a chicken, regardless of the force applied, will not cook it. Cooking requires sustained heat to raise the internal temperature of the chicken to a safe level for consumption.
Cooking involves the application of heat over a period of time to raise the internal temperature of food, ensuring that it reaches a safe level to kill any bacteria or pathogens present. Slapping a chicken, even at high speeds, does not provide the necessary sustained heat required for cooking.
To properly cook a chicken, various cooking methods are used, such as roasting, grilling, frying, or boiling. These methods involve exposing the chicken to a controlled heat source for a sufficient duration. The heat allows the chicken to cook evenly and reach the recommended internal temperature of at least 165°F (74°C) to ensure it is safe to consume.
It's important to follow proper cooking techniques and guidelines to ensure food safety and achieve desirable results. Slapping a chicken, while it may result in physical impact or tenderizing the meat, does not provide the necessary cooking conditions to render the chicken safe, delicious, and suitable for consumption.

Suppose that a driver applies a force of 140 N to the master cylinder, which has a diameter equal to 14 the diameter of the brake cylinder. What is the force applied by the brake cylinder on the brake shoe?
Answers
Answer:
force on brake shoes is 10 N
Explanation:
for the master cylinder;
force applied = 140 N
diameter = 14d
for brake cylinder;
force applied on the brake shoe by the brake cylinder f = ?
diameter = d
The pressure will be transmitted undiminished from the master cylinder to the brake cylinder according to pascals pressure law.
pressure = force/area
but cross sectional area is proportional to diameter of the cylinder
therefore
\(\frac{140}{14d } = \frac{f}{d }\)
the diameters will cancel out, and we're left with
force on brake shoes = 10 N

Which of the four listed units would not be appropriate for describing a rotational acceleration. Or are they all appropriate units of rotational acceleration? Explain.
1) rad/s
2) rev/s^2,
3) rev/m^2
4) degrees/s^2?
Answers
Units 1 ("rad/s"), 2 ("rev/s^2"), and 4 ("degrees/s^2") are appropriate for describing rotational acceleration. However, unit 3 ("rev/m^2") is not suitable as it combines angular displacement with area and does not represent rotational acceleration.
Out of the four listed units, the third unit, "rev/m^2," would not be appropriate for describing rotational acceleration.
1) "rad/s" (radians per second) is an appropriate unit of rotational acceleration. Radians are a standard unit for measuring angles, and when divided by time, it represents the rate of change of angular velocity or rotational acceleration.
2) "rev/s^2" (revolutions per second squared) is also an appropriate unit of rotational acceleration. It represents the rate of change of angular velocity in terms of revolutions per second squared.
4) "degrees/s^2" (degrees per second squared) is another valid unit of rotational acceleration. Although radians are generally preferred over degrees in scientific calculations, degrees can still be used to express rotational acceleration.
However, the third unit, "rev/m^2" (revolutions per square meter), is not appropriate for describing rotational acceleration. It does not represent a rate of change of angular velocity or rotational acceleration. Instead, it combines a unit of angular displacement (revolutions) with a unit of area (square meter), which is unrelated to rotational acceleration.
In summary, the first three units ("rad/s," "rev/s^2," and "degrees/s^2") are appropriate for describing rotational acceleration, while the fourth unit ("rev/m^2") is not.

A 2.72 A current flows through a wire for
9.88 s. How much charge flows past a point
in the wire in that time?
Answers
\(\\ \rm\longmapsto I=\dfrac{Q}{t}\)
\(\\ \rm\longmapsto Q=It\)
\(\\ \rm\longmapsto Q=2.72\times 9.88\)
\(\\ \rm\longmapsto Q=26.87C\)
The amount of charge that flows past a point in the wire during that time is approximately 26.8976 Coulombs.
Electric charge is quantized, meaning it exists in discrete amounts and is measured in coulombs (C). The elementary charge, represented by the symbol "e," is the charge of a single proton or electron, approximately equal to 1.602 x 10^-19 coulombs. Protons carry a positive charge, while electrons carry an equal but opposite negative charge.
When electric charges are stationary, they create an electric field around them. When charges are in motion, they produce a magnetic field in addition to the electric field, leading to electromagnetic effects.
Charge is a fundamental property of matter that determines its interaction with electric and magnetic fields and is crucial to understanding and explaining various electrical and electromagnetic phenomena in the natural world.
To calculate the amount of charge that flows past a point in the wire use the equation:
Q = I * t
Where:
Q is the charge (in Coulombs)
I is the current (in Amperes)
t is the time (in seconds)
Given:
Current (I) = 2.72 A
Time (t) = 9.88 s
Substitute these values into the equation to find the charge:
Q = I t
Q = 2.72 A * 9.88 s
Calculating the product:
Q = 26.8976 C
Therefore, the amount of charge that flows past a point in the wire during that time is approximately 26.8976 Coulombs.

Answers
Pericles, a talented orator and famous Athenian democrat, erred in the late 450s B.C.E. when he advised Athens to fight the Peloponnesian War.
Athens fought Sparta and its allies from 431 to 404 B.C.E. Pericles is known for his political leadership and oratory, yet his war push hurt Athens.
Pericles believed Athens could defeat Sparta and her allies militarily and economically, and he regarded the war as an opportunity to enhance Athens' dominance and influence. He felt that the long walls connecting Athens to Piraeus would protect the city against Spartan attacks, allowing it to survive a long war.
Pericles overestimated Sparta's and its allies' might. Athens was financially and militarily drained by the conflict. Due to the Spartan colonisation of Attica, the Athenians were imprisoned within their city walls, which caused congestion and a terrible disease in 430 B.C.E., weakening Athens.
Pericles' campaign also strained relations with Greek city-states. Many distrusted Athens' aggressiveness and imperial ambitions and joined with Sparta against them. Athens lost diplomatic assistance and was isolated throughout the war.
In 404 B.C.E., Sparta overcame Athens, overthrowing its democracy. Athenian power, territory, and adversaries' harsh terms declined during the war.
Pericles' mistake in encouraging Athens to fight the Peloponnesian War hurt the city-state and democracy. Despite his oratory and leadership skills, this decision contributed to Athens' collapse and the end of its Golden Age.

A 4000-kg car bumps into a stationary 6000kg truck. The Velocity of the car before the collision was +4m/s and -1m/s after the collision. What is the velocity of the truck?
Answers
Answer:
-4.33m/s
Explanation:
Using the law of conservation of momentum
m1u1+m2u2 = (m1+m2)v
m1 and m2 are the masses
u1 and u2 are their respective velocities
v is the final velocity
From the question;
m1 = 4000kg
m2 = 6000kg
u1 = 4m/s
u2 = ?
v =-1m/s
Substitute into the formula and get u2
4000(4)+6000u2 = (4000+6000)(-1)
16000 + 6000u2 = -10000
6000u2 = -10000-16000
6000u2 = -26000
6u2 = -26
u2 = -26/6
u2 = -13/3
u2 = -4.33m/s
Hence the velocity of the truck is -4.33m/s

The earth wire is now connected to the metal case of the washing machine. Explain why it would now be safe for a person to touch the metal case, even if the live wire touches the metal case.
Answers
When the earth wire is connected to the metal case of the washing machine, it provides an alternative pathway for electric current to flow if there is a fault, such as if the live wire touches the metal case. The earth wire is connected to the ground, which has zero potential, so any current that flows through the earth wire will not harm a person who touches the metal case. This is because the person's body is also at zero potential (ground potential) and there will be no potential difference (voltage) across the person's body, which means no electric current will flow through the person's body. Therefore, connecting the earth wire to the metal case of the washing machine ensures that any electrical faults will be safely conducted away from the person, reducing the risk of electric shock or electrocution.
