Why are the incident and emergent rays parallel to each other in case of rectangular glass slab? |
| Answer» In a\xa0rectangular glass slab, the\xa0emergent Ray\xa0is\xa0parallel\xa0to the direction of the\xa0incident ray. The extent of bending of the\xa0ray\xa0of light at the opposite\xa0parallel\xa0faces of the\xa0rectangular slab\xa0is equal and opposite. This is why the rat emerges\xa0parallel\xa0to the\xa0incident ray.\xa0This is because in the case of the\xa0glass slab\xa0the surfaces (on which light is\xa0incident\xa0and emerging) are opposite and\xa0parallel\xa0to each other. Whereas, in the case of a\xa0glass prism\xa0the surfaces are inclined to each other at some angle. | |

How is regeneration of simple organisms different from complex organisms?? Write 4 points. |
| Answer» Regeneration happens through mitosis and a particular type of tissue can give rise to its own kind only. In complex organisms, different tissues and organs have altogether different structures. Regenerating a different kind of tissue from another kind is not possible. Hence, complex organisms are unable to give rise to new individuals through regeneration. | |

Explain construction and working of an electric motor with labelled diagram |
| Answer» An electric motor is a device which converts electrical energy into mechanical energy. The principle behind the electric motor is based on Fleming’s left hand rule.Working: When a current is allowed to flow through the coil PQRS the coil starts rotating anti-clockwise. This happens because a downward force acts on length PQ and at the same time, an upward force acts on length RS. As a result, the coil rotates anti-clockwise.Current in the length PQ flows from P to Q and the magnetic field acts from left to right, normal to length PQ. Therefore, according to Fleming’s left hand rule, a downward force acts on the length PQ. Similarly at an upward force acts on the length RS. These two forces cause the coil to rotate anti-clockwise.When coil complete half rotation, the position of PQ and RS interchange. The half-ring D comes in contact with brush A and half-ring C comes in contact with brush B. therefore the direction of current in the coil PQRS gets reversed. Now the current flows through the coil in the direction SRQP.The direction of current through the coil PQRS reverse after every half rotation. As a result, the coil rotates in same direction. The split rings help to reverse the direction of current in the circuit. These are called the commutator. | |

Draw a labeled diagram showing internal sturcture of human heart |
|
Answer» How can you draw it Can you give the steps for making this diagram??? The heart is roughly cone shaped hollow organ. It is approximately the size of owner’s closed fist and weighs about 250-300 gm in female and 300-350gm in the male. The heart lies in the thoracic cavity in the space between the lungs (mediastinum) anterior to the vertebral column and posterior to the sternum. The heart consists of 4 chambers. At first, the heart is divided into the right and left side by the septum. Each side is further divided into 2 chambers each by the atrioventricular valve. The upper two chambers are called atrium and lower two are called ventricles. Atrium are thin-walled chamber separated by an interauricular septum The right atrium receives impure blood from the body through the opening via superior and inferior vena cava. Ventricles are a thick-walled chamber. separated by the thick inter-ventricular septum. |

Explained in short about four organs of human excretory system |
|
Answer» \xa0Kidneys: They are a pair of bean-shaped, reddish brown organs that help in maintaining the water and salt concentration of blood by the process of osmoregulation.Ureters: They carry urine from each kidney to the urinary bladder.Urinary bladder: They store urine until it is expelled from the body.Urethra: It is a short tube through which urine is passed out. \xa0(a) In humans, the excretory system consists of a pair of kidneys, a pair of ureters, urinary bladder and urethra.(b) Kidneys are two bean shaped organs lying at the back of the abdomen, one on either side of the vertebral column. Waste products from the blood and urine are removed by the kidney.(c) A Nephron is the basic filtration unit of the kidney. It is a cluster of thin walled blood capillaries.(d) The urine produced by filtering the blood is transported to the urinary bladder. This is done by a pair of ureters. Ureters are long muscular tubes.(e) Urinary bladder is a muscular bag like structure which can hold urine. The urinary bladder is under the control of nerves. When the bladder is full one get urge to urinate.(f) This urine is thrown out of the body through urethra.(g) Apart from the kidney, the skin and lungs are also helpful in the excretion. |

How regeneration take place in complex organisms?? |
| Answer» Simple organisms are capable of producing new organisms through the process of regeneration. This is possible in simple organisms because the entire body is made up of similar kind of cells in which any part of their body can be formed by growth and development.In case of the complex organisms have organ system level organization. all the organ systems of their body work together as an interconnected unit.\xa0The tissues in complex organisms cannot regenerate a new individual as they are highly differentiated to perform specialized functions. For example, human skin cannot regenerate into a new individual as it is a highly differentiated tissue performing a designed function. | |

What is the of v-i graph for metallic wire ?why? |
| Answer» The I-V graph of metallic conductor is a straight line pass through the origin. They obey Ohm’s Law, having resistance that is independent of current. (Ohmic conductors)Reason:\xa0Resistance in metal is the reduction of the drift velocity of electrons due to collision with the lattice ions. If the temperature of the conductor is kept constant, the magnitude of the vibration of the lattice ions remain the same, and hence it’s resistance would remain the same. | |

Why are ionic compounds able to conduct electricity |
|
Answer» Ionic compounds are formed by transfer of ions.That\'s why it conducts electricity Answer:\xa0Ionic compounds are formed by transfer of electrons between metals and non metals resulting into cations and anions respectively. They are held by strong electrostatic forces and thus cannot be separated.But when ionic compounds are dissolved in water, they result into ions due to high dielectric constant of water, thus the production of ions help to carry electrons and thus conduct electricity. |

Why in series connection current remains same and potential changes? Explain it practically |
| Answer» \xa0\xa0Current and Resistance in series connection of resistors\tSeries connection is a combnation of resistors connected end to end.\tIt forms a linear connection arrangement of all the resistors connected in series.\tSo\xa0the amount of current flowing through each resistor is equal to the amount of current flowing through the entire circuit.\tThus,\xa0in series connection the current remains same across the resistors.\tThe equivalent resistance of such resistors is given by the sum of resistances of all the resistors connected in series.\tMathematically,\xa0\tThis explains that the resistance of the entire circuit of resistors connected in series will be more than the resistance of the individual resistors.\tResistance is the actual resistance to the flow of current through the circuit.\tTherefore as the equivalent resistance of the resistors connected in series gets added up, the flow of current in a series circuit decreases due to this added resistance. | |
