What are the features of striated muscle fibres |
| Answer» \xa0Striated muscle are called as striped or skeletal or voluntary.\xa0The entire muscle show alternate dark and light strips and therefore called stripped muscle.\xa0They are attached to bones and are responsible for body movement,and therefore called voluntary muscles.\xa0Striated muscles fibres are long or elongated,unbranched,have many nuclei.Each muscle cell is enclosed in a thin but distinct plasma membrane called sarcolemma.These muscles are present in limbs,face,neck,tongue,pharynx,diaphragm. | |

What is zygote |
| Answer» A zygote is a eukaryotic cell formed by a fertilization event between two gametes . The zygote\'s genome is a combination of the DNA in each gamete, and contains all of the genetic information necessary to form a new individual. In multicellular organisms, the zygote is the earliest developmental stage. In single-celled organisms, the zygote can divide asexually by mitosis to produce identical offspring. | |

Differentiate between distance n displacement |
|
Answer» Distance means any object travelled from the initial to final and itis a scalar quantity. And displacement means the short est distance measured in two points is called displace ment . It is vector quantity Distance can\'t be zero and Displacememt can be zero Distance is nothing but total path covered by any body but displacement is shortest path between starting and ending point. Distance is the length travelled by object from its initial to final position but displacement is the shortest distance travelled by object from its position. |

What is the meaning of conservation of momentum? |
|
Answer» It means( momentum before collision=momentum after collision )M1V1+M2V2=M1U1+M2U2 Conservation of momentum simply means that momentum is conserved before and after any action , hence the product of mass and velocity is same before and after the action. It means that how can we conserve and balance the initial and the final momentum. The meaning of conservation of momentum means the thing which is in movment |

What happens when you pour some Acetone on your plam |
|
Answer» When we pour some acetone on our hand it receives the latent heat from our hand to evaporate and we feel cool When we pour some acetone on our palm , it evaporates quickly by the heat energy provided to it by our palm. As it\'s boiling point is very low it evaporates very quickly. As the acetone takes heat energy from our palm , our palm looses temperature and we experience cooling effect of evaporation on our palm When we pour some acetone on our palm , it makes us feel cool by evaporating the heat of our body. I don\'t knoe |

Derive second law of motion from first law of motion |
|
Answer» According to Newton\'s first law of motion a body at rest will remain at rest and if a body at motion will countinue in motion unless it is compelled to exert force changing the state of rest or uniform motion.According to the Newton\'s second law of motion change in momentum with respect the time. you helped alot. The question is wrong I think it should be derive 1st law of motion from second law ❤❤? |

To study the third law of motion using spring balance |
| Answer» Newton’s Third Law of Motion states: ‘To every action there is an equal and opposite reaction’.It must be remembered that action and reaction always act on different objects. The Third Law of Motion indicates that when one object exerts a force on another object, the second object instantaneously exerts a force back on the first object. These two forces are always equal in magnitude, but opposite in direction.These forces act on different objects and so they do not cancel each other. Thus, Newton’s Third Law of Motion describes the relationship between the forces of interaction between two objects.Whenever two bodies interact with each other, the force exerted by the first body on the second is called action. The force exerted by the second body on the first body is called reaction. The action and reaction are equal and opposite.For example, when we placed a wooden block on the ground, this block exerts a force equal to its weight, W = mg acting downwards to the ground. This is the action force. The ground exerts an equal and opposite force W’ = mg on the block in the upward direction. This is the reaction force. | |

If kinetic energy of a body increases by 300% then its momentum increased by |
| Answer» Kinetic energy, KE = (1/2) × m×v²Linear momentum, P = m vif kinetic energy of the body is increase by 300% thenNew KE becomes 4 times (1/2)×m ×v²and\xa0can be given as (1/2)× m ×(2v)²since\xa0other factors will not change being constants.∴ New Linear momentum becomes 2 (m v) i.e. increased by 100% . | |
