Four-wheel drive is a system that powers all four wheels of a vehicle simultaneously for better traction and control.

• It is commonly used in off-road vehicles and SUVs.

• It provides better traction and control on slippery or uneven surfaces.

• Four-wheel drive can be engaged or disengaged depending on the driving conditions.

• It is different from all-wheel drive, which powers all four wheels all the time.

• Examples of vehicles with four-wheel drive include Jeep Wrangler, Toyota 4Runner...read more

Differential in a vehicle allows wheels to rotate at different speeds, enabling smooth turns and preventing tire wear.

• Differential is a mechanism that splits torque between wheels on an axle

• It allows wheels to rotate at different speeds while maintaining power to both wheels

• Without differential, the wheels would be forced to rotate at the same speed, making turns difficult and causing tire wear

• Examples of vehicles with differential include cars, trucks, and motorcycles

Electric cars have batteries at a specific location for optimal weight distribution, safety, and ease of maintenance.

• Optimal weight distribution for better handling and performance

• Safety considerations to protect the battery from impact in case of accidents

• Ease of maintenance for easier access and replacement when needed

No, not all heterocyclic compounds are aromatic.

• Aromaticity depends on the presence of a conjugated ring of atoms with a certain number of pi electrons.

• Heterocyclic compounds may or may not have this conjugated ring structure.

• Examples of non-aromatic heterocyclic compounds include pyridine N-oxide and pyrrole.

• Examples of aromatic heterocyclic compounds include pyridine and furan.

Petrol engines use spark ignition, while diesel engines use compression ignition.

• Petrol engines use a spark plug to ignite the fuel-air mixture, while diesel engines rely on the heat generated by compressing air to ignite the fuel.

• Petrol engines typically have higher RPMs and power outputs compared to diesel engines.

• Diesel engines are more fuel efficient and have higher torque at lower RPMs compared to petrol engines.

• Petrol engines are more common in passenger cars, while die...read more

Piston rings are crucial components in internal combustion engines that prevent oil and fuel from leaking into the combustion chamber.

• Piston rings create a seal between the piston and cylinder wall, allowing the engine to build compression and power.

• They also help regulate oil consumption and prevent excessive oil from entering the combustion chamber.

• Piston rings can wear out over time, leading to decreased engine performance and increased oil consumption.

• Different types of p...read more

Patents are important for protecting intellectual property and promoting innovation.

• Patents provide inventors with exclusive rights to their inventions for a certain period of time.

• They encourage innovation by rewarding inventors for their creativity and hard work.

• Patents help prevent others from copying or using an invention without permission.

• Patents can also be used to generate revenue through licensing or selling the rights to the invention.

Patents are legal protections granted by the government to inventors, giving them exclusive rights to their inventions for a certain period of time.

• Patents provide inventors with the exclusive right to make, use, and sell their inventions for a limited period of time.

• They encourage innovation by rewarding inventors with a temporary monopoly on their creations.

• Patents can cover a wide range of inventions, including products, processes, and designs.

• In exchange for the exclusive...read more

A carburettor is a device in an internal combustion engine that mixes air with a fine spray of liquid fuel.

• Device in internal combustion engines

• Mixes air with liquid fuel

• Controls the air-fuel mixture for combustion

• Commonly found in older vehicles

DNA is a molecule that contains the genetic instructions for the development and functioning of all living organisms.

• DNA stands for deoxyribonucleic acid.

• It is a double-stranded helix structure made up of nucleotides.

• DNA carries the genetic information that determines an organism's traits and characteristics.

• It is found in the nucleus of cells and also in some organelles.

• DNA replication is the process by which DNA is copied during cell division.

• Mutations in DNA can lead to ge...read more

RNA stands for ribonucleic acid, a molecule that plays a crucial role in protein synthesis and gene expression.

• RNA is a single-stranded nucleic acid molecule composed of nucleotides.

• It is involved in various biological processes such as transcription, translation, and regulation of gene expression.

• There are different types of RNA, including messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).

• mRNA carries genetic information from DNA to the ribosomes for protei...read more

Proteins are large, complex molecules that play essential roles in the structure, function, and regulation of cells and tissues.

• Proteins are made up of amino acids, which are linked together in a specific sequence.

• They have diverse functions, including enzymes, antibodies, transporters, and structural components.

• Proteins can be found in all living organisms, from bacteria to humans.

• Examples of proteins include hemoglobin, insulin, collagen, and antibodies.

An AVL tree is a self-balancing binary search tree where the heights of the two child subtrees of any node differ by at most one.

• AVL tree was named after its inventors Adelson-Velsky and Landis.

• Insertions and deletions in AVL trees are performed to maintain the balance factor of each node.

• AVL trees are commonly used in database indexing and in-memory database systems.

Deadlock is a situation in which two or more competing actions are each waiting for the other to finish, preventing any of them from progressing.

• Occurs in concurrent programming when two or more processes are unable to proceed because each is waiting for the other to release a resource

• Can happen in database systems when two transactions are each waiting for a resource locked by the other

• Commonly seen in multi-threaded applications where threads are waiting for each other to r...read more

Sampling is the process of selecting a subset of individuals or items from a larger population to gather information or make inferences.

• Sampling helps in making predictions about the entire population based on the characteristics of the sample.

• There are different sampling methods such as random sampling, stratified sampling, cluster sampling, and convenience sampling.

• Sampling error can occur if the sample is not representative of the population.

• Example: A researcher wants to ...read more
