Find the mass of 1 litre of water |
|
Answer» tion:One litre of water has a MASS of almost exactly one kilogram when MEASURED at its maximal density, which occurs at about 4 °C. It follows, therefore, that 1000th of a litre, known as one MILLILITRE (1 mL), of water has a mass of about 1 g; 1000 LITRES of water has a mass of about 1000 kg (1 TONNE). |

The angle between an incident ray and the mirror is 30° (a) what is the angle of incidence (b) angle of reflection(c) total angle turned by the ray of light |
|
Answer» (a) The angle between the mirror and the incident ray is 30 degrees. The sum of the angle of incidence and this angle (30) MAKES a RIGHT angle. So, the angle of incidence is 90 - 30 = 60 degrees. As the angle of incidence and the angle of REFLECTION are equal, both angles equal 60 degrees.Explanation:Hope so you are satisfied with the answerIf so PLEASE follow....... |

A driver doubles his speed how will it affect his kinetic energy. justify your answer. |
| Answer» TION:The CHANGE in the kinetic energy of the object as the speed changes is proportional to the square of the factor by which the speed changes. If the speed of the object becomes double, its kinetic energy changes to FOUR times the INITIAL kinetic energy. | |
| 7413. |
If a car driver doubles its speed than how will it change kinetic energy |
|
Answer» An important fact to know is that kinetic ENERGY increases exponentially; this means that if you double your VEHICLE's speed, your vehicle's kinetic energy increases by four TIMES. This ALSO means your braking and stopping distance will be MULTIPLIED by four. |

Answer» enough - traveling in the cargo hold poses dangers for any live animal including your PET. If you have a choice, travel by CAR or by train. If you must travel by air, use common sense; know that, if your DOG is old, unhealthy, or is a snub-nosed breed, you need to take extra precautions. If for any reason you cannot travel on the same flight with your pet or if you are traveling to a country with complicated requirements or dealing with a foreign language issue, you may want to use the services of a LICENSED pet transporter. |

Give 2 examples where the object possesses both kinetic energy and potential energy simultaneously |
|
Answer» It is possible for an OBJECT to have both these energies simultaneously. The condition for that is the object should be in motion and should be above ground. An EXAMPLE is a stone falling from a HEIGHT. It is in motion, hence has KINETIC energy and it has potential energy, since it is above the ground |

Why do we sort materials into groups? Based on what properties materials are sorted into groups? |
|
Answer» Why do we SORT materials into groupsAns. Materials are grouped together on the basis of similarities and differences in their properties. Materials are grouped together for convenience and to study their properties. Grouping materials SAVES our time, energy and makes our WORK easier.Based on what properties material are sorted into GROUPS?Based on what properties material are sorted into groups?Ans. Other Criteria For Sorting Materials:Other Criteria For Sorting Materials:The appearance depends on colour, hardness, texture, and lustre. Hardness: hardness is another property of materials. Some materials are very hard while some are very soft. Hard: Material which are difficult to compress are called hard, e.g. diamond, stone, wood, steel, etc.hope it helps YOUMARK my answer as brainliest answerthank you |

What is periodic table |
|
Answer» Hope it helps youExplanation:Periodic table, in full periodic table of the elements, in chemistry, the organized array of all the chemical elements in order of increasing atomic number—i.e., the TOTAL number of protons in the atomic NUCLEUS. When the chemical elements are thus ARRANGED, there is a recurring pattern CALLED the “periodic law” in their properties, in which elements in the same column (GROUP) have similar properties. The initial discovery, which was made by Dmitry I. Mendeleyev in the mid-19th century, has been of inestimable value in the development of chemistry. |

(ii) Real expansion of liquids is more than the observed expansion. why? |
|
Answer» When a liquid is heated in a container, heat flows through the container to the liquid; which MEANS that the container expands first, due to which the LEVEL of the liquid falls. When the liquid gets heated, it expands more, beyond its original level. We cannot OBSERVE the intermediate STATE. |
