Effect of mass |
| Answer» Mass effect\xa0is basically the\xa0physics\xa0of the game. ...\xa0Mass effect\xa0fields are created through the use of element zero. Element zero can increase or decrease the\xa0mass\xa0content of space-time when subjected to an electrical current via dark energy. With a positive current,\xa0mass\xa0is increased.\xa0The strength of the\xa0gravitational\xa0force between two objects depends on two factors,\xa0mass\xa0and distance. the force of\xa0gravity\xa0the\xa0masses\xa0exert on each other. If one of the\xa0masses\xa0is doubled, the force of\xa0gravity\xa0between the objects is doubled. increases, the force of\xa0gravity\xa0decreases. | |

What are the other applications of Ultrasonic sound (any two) |
| Answer» Medical 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.\xa0 | |

Why if the moon suddenly disappeare |
| Answer» And since the ocean is so big, all the water from one horizon pushes up against water from the other, resulting in a fantastic tidal bulge.\xa0If the moon disappeared, we wouldn\'t be totally out of tidal luck; the sun also stretches and squeezes the Earth, so our surfing opportunities wouldn\'t be completely eliminated.\xa0Since the\xa0moon\xa0affects the altitude and movement of Earth\'s water, our ocean tides\xa0would\xa0shrink. Scientists suggest that without the\xa0moon, tides\xa0would\xa0be 1/3 of the size they are now. High tides\xa0would\xa0be much smaller than they are now, and low tides\xa0would\xa0be even lower. | |

Butter is generally wrapped in wet cloth during summer if no refrigerator is available.explain. |
|
Answer» In summer ,the weather is a quite hot. As a result,water present in wet cloth readily evaporates. Since cooling is caused during evaporation,the temperature of butter gets lowered.this checks the rancidity of butter or it doesn\'t give any foul odour. Normally, butter melts due to heat in summers, unless stored in adequate coolness.If refrigerator is not available in a household, butter is wrapped in a wet cloth to provide the required cooling.When the water from the wet cloth evaporates, the butter wrapped inside becomes cooler and thus remains in solid state even during summers. |

Is matter continuous? |
|
Answer» However, there is another nature associated with matter, which is wave like nature. You will study about this in more detail in grade 11, where an entire chapter has been devoted to this. Sub-atomic particles like electrons very well exhibit wave nature along with particle nature. However this wave nature is not shown by macroscopic objects which are easily observable. The wavelength that is associated with these objects is too small and not appreciable. Matter is composed of very small particles called atoms, hence matter is not continuous but particulate in nature. |

Why does the skin of your fingers shrink when you wash clothes for a long time? |
| Answer» When we wash clothes, our hands are exposed to water for a long time. Our hands behave as hypertonic solution and the outside of our hands behave as hypotonic solution. Hence, water flows from high concentration to low concentration. The water is not entering your hands, it actually leaves them and hence, they shrink. | |
| 8741. |
How do substances like CO2 and water move into and out of the cell? Discuss. |
| Answer» The substances like CO2 and water move in and out of a cell by diffusion from the region of high concentration to low concentration. When the concentration of CO2 and water is higher in external environment than that inside the cell, CO2 and water moves inside the cell. | |
| 8742. |
How can we define interia |
| Answer» \tInertia is the natural tendency of an object to resist a change in its state of motion or of rest.\tThe mass of an object is a measure of its inertia.\tA force that is just enough to cause a small cart to pick up a large velocity will produce a negligible change in the motion of a train, because of train’s large inertia. | |

What is mitosis lipids meosis |
| Answer» There are two types of cell division: mitosis and meiosis. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Mitosis gives identical cells to each other and to the mother cell, while meiosis leads to genetic variation due to crossing over and independent assortment. Mitosis gives nuclei with the same number of chromosomes as the mother cell while meiosis gives cells with half the number. | |

When the particle in a mixture are the size of atom or molecule |
| Answer» The size of the particles which make up matter are very, very small. This can be shown by performing the given experiment:i. Take 2-3 crystals of potassium permanganate and dissolve them in 100 mL of water.ii. Take out approximately 10 mL of this solution and put it into 90 mL of clear water.iii. Take out 10 mL of this solution and put it into another 90 mL of clear water.iv. Keep diluting the solution like this 5 to 8 times.This experiment shows that just a few crystals of potassium permanganate can colour a large volume of water (about 1000 L). So we conclude that there must be millions of tiny particles in just one crystal of potassium permanganate, which keep on dividing themselves into smaller and smaller particles. | |
