How can you prove that a mixture contains more than one substance |
|
Answer» Water is a mixture of h2 and o(i-e hydrogen 2 and one oxygen) therefore we can say that a mixture is constituted by more than one substance A mixture is a material system made up of two or more different substances which are mixed but not combined chemically. a mixture refers to the physical combination of two or more on which the identities are retained and are mixed in the form of solutions, suspensions and colloids Sublmasation |

Balanced and unbalanced force |
|
Answer» Dog Any push or pull is a force. To describe a force, you must know two things. You must know the size of the force and the direction of the force. Suppose two teams are playing tug of war. Each team is pulling with equal force, but in opposite directions. Neither team can make the other team move. Forces that are equal in size but opposite in direction are called balanced forces.tug of war balancedBalanced forces do not cause a change in motion. When balanced forces act on an object at rest, the object will not move. If you push against a wall, the wall pushes back with an equal but opposite force. Neither you nor the wall will move. Forces that cause a change in the motion of an object are unbalanced forces.tug of war unbalanced 1Unbalanced forces are not equal and opposite. Suppose that one of the teams in tug of war pulls harder than the other team. The forces would no longer be equal. One team would be able to pull the other team in the direction of the larger force. |

what is the temperature of plasma |
| Answer» 30,000°A plasma is a gas, but it is an unusual kind of gas. In a normal gas, the atoms or molecules are electrically neutral, but in a plasma at least some of these particles have either lost or gained an electron, so that a plasma consists of free electrons and positively or negatively charged atoms and molecules known as ions. A high temperature must be reached before a normal gas can be transformed into a plasma. The lowest temperature at which plasma can usually be seen is a few tens of thousands of degrees, but many plasmas are much hotter than this. Plasmas can reach temperatures of hundreds of thousands or even millions of degrees. Relatively cool plasmas usually have a distinctive luminous colour that depends on the gas in which the plasma is formed. | |

What is mitocondria |
|
Answer» Mitrochondria Mitochondria are round "tube-like" organelles that provide energy to a cell in the form of ATP (Adenosine Triphosphate) for performing different chemical activities for the sustainance of life.The mitochondria is also called powerhouse of the cell.Mitochondria have their own DNA and ribosomes and are hence capable to produce some of their required proteins all by themselves. Powerhouse of the cell. |

Why does ice at 0 degree cause more cooling than water at 0 degree? |
| Answer» Ice is more effective in cooling than water at the same temperature because ice can absorb latent heat as well as the heat energy in order to attain room temperature. Water at\xa00C can absorb heat energy only to attain the room temperature. Thus water can absorb less amount of energy from surroundings compared to ice due to which ice will give more cooling effect as compared to water at the same temperature. | |

Define Hybridisation. |
| Answer» Hybridization is the crossing of dissimilar individuals to produce best of both organisms. It might be of interbreeding between individuals of different species (interspecific hybridization) or genetically divergent individuals from the same species (intraspecific hybridization). One advantage of hybridization is that it can combine disease resistance of one organism with the production capacity of another.Crop yields increase dramatically when hybridization is used to exceed one or more of the parents in size and reproductive potential. | |

What is Protons and neutrons? |
| Answer» Proton (p+) - Proton is denoted by ‘p’ and is positively charged particle. The absolute charge over proton is 1.6x10 -19 coulomb of positive charge and it is considered as unit positive charge. Thus absolute charge over a proton is equal to +1.Electron (e– )- Electron is denoted by ‘e’ and is a negatively charged particle. The absolute charge over an electron is equal to 1.6x10-19 of negative charge and is considered equal to – 1. | |

What is the third law of motion? |
|
Answer» Every action has an equal and opposite reaction on two different objects. Third law of motion states that every action has a equal and opposite reachtion.That means that if object m1 hits the object m2 So according to Newton,s third law of motion m2 will react to m1 Third law of motion gives idea of cause and effect. The second law of motion states that : Whenever one body exerts a force in another body , the second body exerts sn equal and opposite force on the first body. To every action there is a equal and opposite reaction To every action there is an equal but in opp. reaction |
