Metal brushes slide up against the co-rotating cylinders that the coil is attached to before making contact and Nab =0.8148946
Given :2πfNabB sin (2πft) = ε0 sin (2πft).
2πfNabB = ε0
Nab= ε0 /2πfB
since,ε0 = 248 V
f=76.8 rev/s
B = 0.631 T
π=3.14
now substituting the above values in Nab= ε0 /2πfB
we get, Nab= 248/2 X3.14 X76.8 X0.631
= 248 /304.3333824
therefore , Nab =0.8148946
A coil-shaped electrical conductor, such as a wire, serves as an electromagnetic coil (spiral or helix). In devices like electric motors, generators, inductors, electromagnets, transformers, and sensor coils—where electric currents and magnetic field interact—magnetic coils are utilized in electrical engineering. Either an electric current is sent through the coil's wire to produce a magnetic field, or an external, time-varying magnetic field passes through the coil's interior to produce an EMF (voltage) in the conductor.

the layer of the meninges in direct contact with the spinal cord is the choroid plexus. arachnoid mater. dura mater. pia mater. subarachnoid space.
Pia mater is the layer of meninges that is in direct contact with spinal cord.
What are the meninges?
The meninges are the membrane-like linings that protect the brain and spinal cord. The dura mater, arachnoid mater, and pia mater are the names of the three layers that make up the meninges.
The two primary purposes of these covers are:
To support the cerebral and cranial arteries, provide a framework.
Utilizing cerebrospinal fluid to shield the central nervous system (CNS) against harm.
Subarachnoid space is located underneath the pia mater. It covers the surface of the brain and spinal cord and is firmly attached despite being quite thin. The shape of the brain is exclusively followed by this covering (the gyri and fissures).Similar to the dura mater, it is heavily vascularized, with blood veins puncturing the membrane to supply the underlying neural tissue.
Astrocyte processes serve as the pia mater's anchors. At the CNS surface, a layer of astrocyte "end feet" is where the pia mater joins. It is challenging to pinpoint the precise boundary between the arachnoid matter and pia mater because the arachnoid trabeculae that cross the subarachnoid space really integrate with the pia mater in a way that is almost imperceptible. This complete leptomeningeal complex is hence sometimes referred to as the pia-arachnoid.
The pia mater is a delicate, fibrous tissue that may let water and tiny solutes pass through it. Blood arteries can flow through the pia mater and hydrate the brain. It is suggested that the perivascular region between blood vessels and the pia mater is a component of the brain's pseudolymphatic system. Meningitis results from irritation and inflammation of the pia mater.

The statement "It has occurred in accordance with the laws of thermodynamics and resulted in a substantial decrease in the entropy of the planet" is true about the evolution of life on earth.
The sophisticated eukaryotic cell signaled the start of an altogether new era for life on Earth when these cells evolved into multicellular creatures.
Evidence is presented to support the idea that eukaryotic cells are fundamentally the result of various prokaryotic cells fusing together in a symbiotic union. In reality, it appears that the mitochondrion is the "great-great-great-great-great-great-great granddaughter" of a free-living bacterium that was ingested by another cell, perhaps as a meal, and ended up lingering as a sort of permanent houseguest.

The statement correctly describing meiosis is meiosis involves four rounds of DNA replication followed by two successive cell divisions. Correct answer: letter D.
This is because meiosis involves two successive cell divisions, known as meiosis I and meiosis II, which follow four rounds of DNA replication. During meiosis I, homologous chromosomes separate, and during meiosis II, the daughter cells divide to form four haploid cells.
What is meiosis?is a type of cell division that produces two daughter cells with half the number of chromosomes of the parent cell. This type of cell division is essential for sexual reproduction, as it allows for the combination of genetic material from two different parents.

Glycolysis is the process of breaking down glucose to produce energy. It generates two pyruvate molecules, ATP, NADH, and water. The process occurs in a cell's cytoplasm and does not require oxygen. It can be found in aerobic and anaerobic organisms.
Glycolysis is a cytoplasmic pathway that converts glucose into two three-carbon compounds while producing energy. Phosphorylation traps glucose with the help of the enzyme hexokinase.
Fermentation is a metabolic process that involves the action of enzymes to produce chemical changes in organic substrates.

which statement is accurate about how c4 plants are able to survive hot, dry spells during the growing season?
RuBP carboxylase is not exposed to the rise in oxygen concentration felt in the leaf when the stomata close due to heat stress. By doing this, the plant can avoid attempting to use oxygen.
C4 plants have developed a method to provide Rubisco with CO2.
Since plants also lose water vapour through their stomata, they are susceptible to dehydration in dry climates where they maintain open stomata for photosynthesis. To avoid drying out, plants close their stomata in response.
In these plants, the initial phosphoenolpyruvate converts carbon dioxide into oxaloacetate in specific mesophyll cells. More biomass can be produced by C4 plants. In general, C 3 plants have a higher rate of photosynthesis per unit of nitrogen.
