Explain first law of motion? |
|
Answer» first law of motion is also known as laws of inertia first laws of motion states that a body at rest will continue to be at rest and a body in motion will continue to be in motion until and unless external force acts on it. \tNewton\'s First Law of Motion:\xa0Any object remains in the state of rest or in uniform motion along a straight line, until it is compelled to change the state by applying external force. This law states that..a body at rest stay at rest or a body in motion stay in motion ..until any external force is applied to them..It is also known as law of inertia ...which are of two types ..1.Inertia of rest 2. Inertia of motion |

Give diff. Between mitosis and meiosis |
| Answer» \tTypesMitosisMeiosisInterphaseInterphase – Chromosomes not yet visible but DNA has been duplicated or replicated.Each chromosome replicates. The result is two genetically identical sister chromatidsProphaseProphase –Each of the duplicated chromosomes appears as two identical or equal sister chromatids, The mitotic spindle begins to form. Chromosomes condense and thickenProphase I – Crossing-over recombination – Homologous chromosomes (each consists of two sister chromatids) appear together as pairs. Tetrad is the structure that is formed. Segments of chromosomes are exchanged between non-sister chromatids at crossover points known as chiasmata (= crossing-over)MetaphaseMetaphase -The chromosomes assemble at the equator at the metaphase plateMetaphase I Chromosomes adjust on the metaphase plate. Chromosomes are still intact and arranged as pairs of homologuesAnaphaseAnaphase – The spindle fibres begin to contract. This starts to pull the sister chromatids apart. At the end of anaphase, a complete set of daughter chromosomes is found each pole.Anaphase I Sister chromatids stay intact. But homologous chromosomes drift to opposite or reverse poles.Types of ReproductionSexualAsexualOccurs inHumans, animals, plants, fungi.All OrganismsFunctionGenetic diversity through sexual reproduction.General growth and cell reproduction, repair of the body.\t | |

Give the application of ultrasound. |
| Answer» Ultrasounds are high frequency waves, which can travel in defined paths even in the presence of many obstaclesMedical applications\tUltrasonic waves are used to capture the images of the heart and its features and problems associated with the heart, if any (for treatment purpose). This is called echocardiography.\tUltrasound scans/Ultrasonography are very commonly used to get images of internal body organs such as liver, kidney, uterus. It helps the doctor to diagnose and treat problems in the body of the patient. In this method, ultrasound waves are made to travel through the body to the organ under consideration. They get reflected and these are converted to electrical signals which can be monitored on a screen.\tUltrasonography is used to observe the growth of the fetus inside the uterus. It can also used to monitor the abnormalities.\tIt is used to break kidney stones into fine grains which later get flushed out through urine. Industrial Applications\tUltrasound is used to clean machine parts located in places which are not easily accesible - electronic components, internal parts, spiral parts etc. The objects are placed in a cleaning solution and waves are passed through it. Because of the high frequency of the waves, the dust particles just fall out.\tIt is used to detect defects, flaws, cracks in machine parts, bridges, building etc. Ultrasound waves are passed at one end and monitored using detectors. If there are laws or cracks, then the ultrasound waves are reflected back indicating the presence of a defect. | |

What is the law of conversation of momentum? Prove it |
|
Answer» exercise 2.1 Itna bhi nhi ataa \tLaw of conservation of linear momentum is a extremely important consequence of Newton\'s third law of motion in combination with the second law of motion. According to law of conservation of momentum\tWhen two or more bodies acts upon each other their total momentum remains constant provided no external forces are acting\tSo, Momentum is never created or destroyed.\tWhen this law is applied for a collision between two bodies, the total momentum of the colliding bodies before collision is equal to the total momentum after collision.\tWe can apply this law for a collision between two vehicles. This law is applicable for all types of collisions. |

What is hypertonic solution? |
|
Answer» If the medium surrounding the cell has low water concentration it is called hypertonic solution If the medium has a lower concentration of water than the cell, meaning that it is a very concentrated solution, the cell will lose water by osmosis. Such a solution is known as a hypertonic solution. Again, water crosses the cell membrane in both directions, but this time more water leaves the cell than enters it. Therefore the cell will shrink. A hypertonic solution is a particular type of solution that has a greater concentration of solutes on the outside of a cell when compared with the inside of a cell. |

Define Buoyant force |
| Answer» In physics, buoyancy or upthrust, is an upward force exerted by a fluid that opposes the weight of an immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus the pressure at the bottom of a column of fluid is greater than at the top of the column. | |

What are the application of sublimation process |
| Answer» Here are several application of sublimation :1.Dry ice sublimes while keeping its area cold. No water is produced to wet things.2.Naphthalene, mothballs, sublime into the air, not getting the area wet, while keeping moths away.3.Iodine can be displaced in a compound and collected on the bottom of a watch glass with ice on top, in deposition, opposite of sublimation.This also occurs as frost is formed on a window from humid air as the dew point falls below freezing. | |

Find acceleration of an object if it is moving with uniform speed of 20m/s for 10seconds |
|
Answer» V=20U=20T=10A=v-u/t=20-20/10=0 U is 20 v is 0 and we know that A is v- u/t 0-20/10 is -2 we the answer is -2 And it is not written in the question whether the obiect started from rest i.e. its initial velocity is zero When an object moves with uniform velocity then its aacleration will be zero.Because its (v-u) will be zero. U-20 (u= initial velocity)V-0. (v=final velocity)T-10secWe know, a=v-u/tA=0-20/10A=-20/10A=-2(A=acceleration) |

How does a desert cooler works? |
|
Answer» In a hot dry day water in desert cooler evaporates by taking energy from the surrounding,and humidity is less and rate of evaporation is high so desert cooler creates cooling The cooling in a desert room cooler is due to the process of evaporation.Desert cooler cools better on a hot dry day because the temperature of the atmosphere increases the rate of evaporation also increases and in hot day the humidity in atmosphere is less.If humidity is less evaporation is more.This gives better cooling effect. |

Explain how Newton\'s second law of motion is used in sports |
| Answer» Law of acceleration: According to this law, A change in motion is directly proportional to the force producing it and inversely proportional to its mass. If two unequal forces are applied to objects of equal mass, the object that has greater force applied will move faster. Conversely, if two equal forces are applied to objects of different masses, the lighter mass will travel at a faster speed.eg. In hammer throw, a thrower who is stronger will throw the hammer farther than a thrower who is less strong. | |
