In a circuit ammeter is connected in series but voltmeter is connected in parallel give reason ?? |
|
Answer» A voltmeter has high resistance so it is connected in parallel. If we connect it in series then current would not able to flow properly which cause voltmeter to burn Voltmeter has the resistance which is high or it is taken as infinity if it would be connected in parallel then all the current will be resisted and current will not be able to flow. In Ammeter it\'s resistance is very low and taken as negligible or zero so it is connected in series.... A\xa0voltmeter\xa0has high resistance and if it is\xa0connected in series\xa0then it would consume all the current\xa0but\xa0an\xa0ammeter\xa0has low reistance and if it is\xa0connected in parallel\xa0then all the current would flow through\xa0ammeter\xa0and nothing would flow in the circuit |

Why does calcium ( Ca) and magnesium (mg) swim in water ? |
| Answer» \u200b\u200b\u200b\u200b\u200b\u200bCalcium reacts with cold water to form calcium hydroxide and hydrogen gas.Heat produced is so less in which is not enough to burn hydrogen gas.The calcium metal floats on water because the bubbles of Hydrogen gas formed during reaction and increase\xa0the volume of the element and stick to its surface.Magnesium metal reacts with hot water to form magnesium hydroxide and hydrogen gas.The magnesium metal floats on water because the bubbles of Hydrogen gas formed during reaction and increase\xa0the volume of the element and stick to its surface.so,because of the evolution of hydrogen gas that occurs by the formation of bubbles Ca and Mg floats on water. | |

Will the current flows more easily through thick wire or thin wire. Give reason? |
|
Answer» Current flows more easily through the thick wire because in a thick wire the electrons get more space to flow and they will not hit more atoms nd the resistance will be less as compared to thin wire.Also resistance is inversely proportional to area of cross section,if area will increase then the resistance will decrease. In thick wire , because resistance is inversely proportional to area of cross section, or agar resistance kam hoga to current jada flow karega , because resistance is inversely proportional to current ? The current will flow more easily through the thick wire than the thin wire. It is because the resistance of a conductor is inversely proportional to its area of cross-section. If the thicker the wire, the less is resistance and hence more easily the current flows. |

What is the difference between displacement and double displacement reaction |
|
Answer» The chemical reaction in which more reactive element displace a less reactive element from a compound are known as displacement.. The chemical reaction in which compounds react to form two different compounds by mutual exchanges of ions are called double displacement reaction.. Displacement reaction\xa0is a chemical\xa0reaction\xa0in which\xa0displacement\xa0of a metal from its solution takes place by the other metal that is more reactive than the metal being\xa0displaced.\xa0Double displacement reaction\xa0is a chemical\xa0reaction\xa0in which exchange of ions between both the reactants takes place. |

How our heart pumps blood . Explain |
|
Answer» Thanks The primary responsibility of the heart is to pump blood throughout the circulatory system. As the center of the circulatory system, the heart is an essential organ for maintaining the overall functioning of the body.The cardiovascular system consists of many veins and blood vessels which ensure that all parts of the body are provided with an adequate amount of oxygen and nutrients to function efficiently. Without a sufficient supply of oxygen, any bodily function would fail, causing organ damage or organ death.Components of the heartFully understanding the heart’s vital function in the body entails the need to first understand its anatomy. As a busy and hardworking organ, the heart needs to closely monitor all of its components to ensure proper functioning. Even a minor cardiac dysfunction may result in significant functional challenges in the total body function of an affected individual.Located at the center of the chest and in the thoracic cavity, the heart can be divided into four parts that are otherwise known as chambers, each of which contains several valves. Two of these chambers, which are called\xa0atria,\xa0are located in the upper portion of the heart and receive oxygen-free blood. The valves that separate these chambers are called\xa0atrioventricular valves, which are composed of the tricuspid\xa0valve on the left and the mitral valve on the right.Image Credit: Olga Bolbot /\xa0Shutterstock.comMeanwhile,\xa0ventricles,\xa0which are the chambers found in the lower portion of the heart, pump oxygen-enriched blood into the body. Similar to the atria, the ventricular chambers are also separated by valves called\xa0semilunar valves. These valves may be further divided into the pulmonary and aortic valves.The heart is also composed of a protective layer that has three parts, which include the outer layer known as the\xa0epicardium, the middle layer known as the\xa0myocardium, and the innermost layer known as the\xa0endocardium. Both the outer and inner layers of the heart are thin; whereas the middle layer, makes up most of the heart and is comrpised of cardiac muscle fibers. |
