Workability of concrete can be determined by conducting a slump test.
Slump test is a simple and widely used method to determine the workability of concrete.
It involves filling a standard slump cone with concrete and then lifting the cone to see how much the concrete slumps.
The amount of slump is measured and compared to a standard chart to determine the workability of the concrete.

CSS stands for Cascading Style Sheets. Time complexity of merge sort is O(n log n) and binary search is O(log n).
CSS stands for Cascading Style Sheets and is used for styling web pages.
Time complexity of merge sort is O(n log n) where n is the number of elements in the array.
Time complexity of binary search is O(log n) where n is the number of elements in the array.
Merge sort has a time complexity of O(n log n) and binary search has a time complexity of O(log n).
Merge sort has a time complexity of O(n log n) because it divides the array into halves and merges them back together.
Binary search has a time complexity of O(log n) because it halves the search space in each iteration.
Example: For an array of size n, merge sort takes O(n log n) time to sort the array and binary search ta

mutable keyword allows a member variable of a class to be modified even if the object is declared as const.
Used to modify a const object's member variable
Does not affect the const-ness of the object itself
Helpful when caching values in a const member function
Inline functions in C++ are functions that are expanded in place at the point of call, rather than being called like regular functions.
Inline functions are typically used for small, frequently called functions to reduce the function call overhead.
They can improve performance by eliminating the function call and return overhead.
Inline functions should be used judiciously as they can increase code size if overused.

Transformers are devices that transfer electrical energy between two or more circuits through electromagnetic induction.
Transformers consist of primary and secondary coils wound around a core made of ferromagnetic material.
They work on the principle of electromagnetic induction, where changing current in the primary coil induces a voltage in the secondary coil.
Transformers are used to step up or step down voltage level...
Microcontrollers are small computers on a single integrated circuit used to control electronic devices.
Microcontrollers are often used in embedded systems for specific tasks.
They contain a CPU, memory, and input/output peripherals on a single chip.
Examples include Arduino, Raspberry Pi, and PIC microcontrollers.

First angle projection is a method of representing a 3D object in 2D by projecting the object onto a plane from the perspective of the viewer.
In first angle projection, the object is placed in the first quadrant of the viewing plane.
The top view is placed above the front view and the side view is placed to the right of the front view.
This method is commonly used in Europe and Asia.
It is important to understand the orie...

The refrigeration cycle is a process that removes heat from a space or substance to lower its temperature.
The cycle consists of four main components: compressor, condenser, expansion valve, and evaporator.
The compressor increases the pressure and temperature of the refrigerant gas.
The high-pressure gas then flows into the condenser where it releases heat and becomes a high-pressure liquid.
The liquid refrigerant passes ...

The resistance is measured in ohms.
Resistance is a measure of how much a material opposes the flow of electric current.
The unit of resistance is ohms (Ω).
Resistance can be calculated using Ohm's Law: R = V/I, where R is resistance, V is voltage, and I is current.
Resistance can vary depending on the material, length, and cross-sectional area of a conductor.
For example, a copper wire with a length of 1 meter and a cross-...
The sensor voltage varies depending on the specific sensor and its application.
Sensor voltage is typically measured in volts (V).
