Explanation:
We assume the T flip-flop changes state on the rising edge of the clock input.
The first stage is connected to the clock. The second stage clock is connected to the inverse of the Q output of the first stage, so that when the first stage Q makes a 1 to 0 transition, the second stage changes state.
Answer:
Explanation:
Carnot cycle
Carnot cycle have four process
1. Iso thermal expansion
2.Reversible adiabatic expansion
3. Iso thermal compression
4.Reversible adiabatic compression
This is ideal cycle for all work producing devices.All devices have efficiency less than Carnot cycle. Because in Carnot cycle all process is reversible process.
Efficiency of Carnot cycle given as
But temperature must be in Kelvin
So
Answer: (B) 100
Explanation:
Given that;
Pstatic = 20 psig , hz = 160ft, hf = 20ft
Now total head will be;
T.h = hz + hf
T.h= 160 + 20
T.h = 180ft
Minimum pressure = Psatic + egh
we know that specific weight of water is 62.4 (lb/ft3)
so
P.min = (20 bf/in² ) + (62.4 b/ft³ × 180 fr
P.min = (20 bf/in² ) + ( 62.4 × 180 × 1 ft²/144 in²)
P.min = 20 + 78
P.min = 98 lbf/in²
Therefore the minimum pressure rating (psi) of the piping system is most nearly B) 100

Hi, you haven't provided the options to the question so I will just give the answer in my own words and you can check with the options.
Answer is INHERITANCE.
Explanation:
In object oriented programming:
An object is a self-contained component that contains properties and methods needed to make a certain type of data useful.
A class is a blueprint or template used to build a specific type of object. Every object is built from a class.
Inheritance is a way to express relationship between classes. Inheritance enables new objects (subclasses) to take on the properties of existing objects (superclasses).
A class that is used as a basis for inheritance is called a superclass or base class or parent class.
A class that inherits from a superclass is called subclass or derived class or child class.
The ability of a subclass to override a method allows a class to INHERIT from a superclass whose behavior is "close enough" and then to modify behavior as needed.
Therefore, the characteristic of object oriented programming that allows the method in subclass that overrides the same method in the superclass to be correctly called from an instance of that superclass is called INHERITANCE.
