In an AC generator, the electrical current reverses direction periodically. In a DC generator, the electrical current flows only in one direction. In an AC generator, the coil through which the current flows is fixed while the magnet moves. The construction is simple and costs are less.

Meghna Thapar 5 years, 2 months ago

The potential difference maintained between the live wire and neutral wire in India is. The potential difference maintained between the live wire and neutral wire in India is 220 V. If the live wire directly come to the neutral wire it is the condition of short circuit. ... In case of Normal wire the wire will burn and then the circuit break and all things become normal except that conductor or wire.

Respiration in human beings

Posted by Aditya Patil 5 years, 3 months ago

CBSE > Class 10 > Science

1 answers

Yogita Ingle 5 years, 3 months ago

Respiration is the process of taking in oxygen and giving out carbon dioxide. There are two types of respiration processes in humans:

External Respiration, that involves the inhalation and exhalation of gases.
Internal Respiration, that involves the exchange of gases between blood and body cells.

Respiration in humans takes place through the lungs. It is the largest organ of the human respiratory system. The air inhaled moves down the trachea into the lungs where oxygen is exchanged for carbon dioxide from the body tissues. Carbon dioxide is then exhaled out of the lungs through the mouth.

Yogita Ingle 5 years, 3 months ago

In 1678, Huygens proposed that every point that a luminous disturbance meets turns into a source of the spherical wave itself. The sum of the secondary waves, which are the result of the disturbance, determines what form the new wave will take. This theory of light is known as the ‘Huygens’ Principle’.

ANSWER

What is the minimum resistance which can be made using five resistor, each of 1/5 ohm.

Posted by Manish Kumar 5 years, 3 months ago

CBSE > Class 10 > Science

3 answers

A . 5 years, 2 months ago

1 ohm

Yogita Ingle 5 years, 3 months ago

When resistors are connected in parallel, the supply current is equal to the sum of the currents through each resistor. In other words, the currents in the branches of a parallel circuit add up to the supply current.

Also, they have the same potential difference across them. In other words, any components in parallel have the same potential difference across them. And, the total resistance will always be lesser than the least resistance in the circuit.

The total resistance is calculated as 1/R_T= 1/R₁+1/R₂+ 1/R3.Thatis,R=R_T⁻¹.

In this case, the given resistance are of 1/5 ohms each. Therefore, the minimum resistance that can be obtained from the parallel connection of these five resistors is given as follows.

1/R_T = 5/1+ 5/1 + 5/1 + 5/1 + 5/1 =25/1.Therefore,R= 1/25.

Hence, the minimum resistance which can be made using five resistors each of 1/5 ohms is 1/25 ohms.

D.R.K Mishra 5 years, 3 months ago

Minimum resistance,R=1/5+1/5+1/5+1/5+1/5 R=(1+1+1+1+1)/5 R=5/5 R=1 •°•Thus, minimum resistance,R is 1

Did you mean budding... If yes then here is your answer ?Budding is a type of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site. The small bulb-like projection coming out from the yeast cell is called a bud. Since the reproduction is asexual, the newly created organism is a clone and excepting mutations is genetically identical to the parent organism. I hope it would be helpful to you...? ✌

Karyokinesis is the process of division of a cell's nucleus during the cell division processes like mitosis and meiosis. ?

Yogita Ingle 5 years, 3 months ago

Karyokinesis is defined as the division of the nucleus during the M phase of the cell cycle. It is the first step in M phase. In this process, the DNA condenses and the chromosomal material divides equally into two halves. This process occurs in four steps-peophase, metaphase, anaphase and telophase.

Yogita Ingle 5 years, 3 months ago

The leaves of touch-me-not plant (Mimosa pudica) folds up in response to touch. This information is traveled from cell to cell by electrical chemical means. Mimosa has pad like swellings called pulvini at the base of each leaf. The folding up of the leaves of a sensitive plant on touching is due to the sudden loss of water from the pulvini.

cerebrum is further divided into four sections or lobes:

Frontal lobe: It is associated with parts of speech, planning, reasoning, problem-solving and movements.
Parietal lobe: Help in movements, the perception of stimuli and orientation.
Occipital lobe: It is related to visual processing.
Temporal lobe: This region is related to perception and recognition of memory, auditory stimuli and speech.

Anamika Jarambusa 5 years, 3 months ago

The brain has three main parts: the cerebrum, cerebellum and brainstem. Cerebrum:is the largest part of the brain and is composed of right and left hemisphere. It performs higher functions like interperting touch, vision and hearing, as well as speech, reasoing emotions, learing, and fine control of movement.

A homologous series is a series of compounds with the same general formula, usually varying by a single parameter such as the length of a carbon chain. Compounds within a homologous series typically have a fixed set of functional groups that gives them similar chemical and physical properties. For example, methane, ethane, propane, butane, etc. are all part of the alkane homologous series.
