An induced current has no no direction of its own. Explain
An induced current is a current that is produced in a conductor when there is a change in the magnetic field surrounding it. Unlike a direct current (DC), which flows continuously in one direction, an induced current is alternating in nature and changes direction periodically. The direction of an inRead more
An induced current is a current that is produced in a conductor when there is a change in the magnetic field surrounding it. Unlike a direct current (DC), which flows continuously in one direction, an induced current is alternating in nature and changes direction periodically.
The direction of an induced current is not determined by the current itself but is instead determined by the direction of the changing magnetic field that is causing the current. According to Faraday’s law of electromagnetic induction, the magnitude and direction of an induced current are proportional to the rate of change of the magnetic field. The induced current will flow in a direction such that it opposes the change in the magnetic field that produced it, as described by Lenz’s law.
Therefore, the direction of the induced current is not determined by any intrinsic property of the current itself, but rather by the external factors that are causing it to be induced.
If magnetic force does not work on charged particles, how can it have any effect on particle motion?
When a charged particle moves on uniform magnetic field (B), it experience a force F as F= Bqv sinΘ, where q is charge particle, v be its velocity and Θ be is angle between B and v. This force is acting toward the motion of the circle or motion is circular. The direction of force F and distance coveRead more
When a charged particle moves on uniform magnetic field (B), it experience a force F as F= Bqv sinΘ, where q is charge particle, v be its velocity and Θ be is angle between B and v. This force is acting toward the motion of the circle or motion is circular. The direction of force F and distance covered s are always perpendicular to each other such that, work done W = FS cos90 = 0. so, the magnetic force does no work done but moves the particle in circular motion.

an earthworm is hermophodite but there is no self fertilization because of proandus ( male gamete and female gamete ).

See lessAnimals are classified into hierarchical groups, in which one of the following, the target number of species is found?
Option A is the correct answer
Option A is the correct answer
See lessHierarchy of categories of Carolus Linnaeus had categories except
Option D is the correct answer !!! Linnaeus proposed that there were three broad groups, called kingdoms. These kingdoms were animals, plants, and minerals. He divided each of these kingdoms into classes. Classes were divided into orders. These were further divided into genera (genus is singular) anRead more
Option D is the correct answer !!!
See lessLinnaeus proposed that there were three broad groups, called kingdoms. These kingdoms were animals, plants, and minerals. He divided each of these kingdoms into classes. Classes were divided into orders. These were further divided into genera (genus is singular) and then species.
The descending arrangement of categories is known as
Option C is the correct answer !!! Hierarcy is the process of arranging taxonomic categories in descending order where species is lowest and kingdom is at top.
Option C is the correct answer !!!

Identify from the following the only category that has a real existence.
Option D is the correct answer !!! A species is defined as the largest group of organisms sharing similar characteristics, capable of interbreeding and produce fertile offspring.
Option D is the correct answer !!!
See lessA species is defined as the largest group of organisms sharing similar characteristics, capable of interbreeding and produce fertile offspring.
