पेज 245 के उत्तर Class 10 Science Chapter 12 Electricity Intext Question answers given on Page 245 are given below. The students preparing for board exams must study hard with dedication to secure a meritorious position. Prepare your subject as per the latest. Ncert Class 10th Science Book is meant to refine and brighten your concepts, doubts and provide students a thorough understanding of difficult topics. These oxides are known as amphoteric oxides.
Does the light ray bend towards the normal or away from the normal? A medium which has the highest refractive index will have the highest optical density and vice-versa. The other one is of black insulation, which is a neutral wire. But before that, the students have to face Class 10 Science Board Exam which is equally demanding. This implies that iron is a better conductor than mercury. The third unit is How things works which have four chapters. Chapter 6 - Life Processes There are total thirteen questions in the chapter of which first four questions are of objective type.
Clearly, the direction of electronic current is from negative terminal to positive terminal. What is the nature of the image? A ray of light travelling in air enters obliquely into water. Since the magnification is 1 it means that the size of the image is equal to the size of the object. The speed of light in vacuum is 3 x 10 8 ms -1. Find out, from Table, the medium having highest optical density. Which of the following lenses would you prefer to use while reading small letters found in a dictionary? Which one of the following materials cannot be used to make a lens? An object 5 cm is placed at a distance of 20 cm in front of a convex mirror of radius of curvature 30 cm.
Answer 2: Ammeter: An ammeter ampere + meter is a device used to measure electric current in a circuit. Name the mirror that can give an erect and enlarged image of an object. In which of these does the light travel fastest? Go back to main page or move to of page. Therefore, the image formed is virtual, erect, and smaller in size. For other answers please visit to or or or or or and or go for Solutions. Remaining questions are of short and long answer type.
The sixth chapter is about the various life processes which human need for their survival. In the last two questions, we have to differentiate between the given two topics. For other answers please visit to or or or or or or or go for Solutions. It is used as a safety measure to ensure that any leakage of current to a metallic body does not give any severe shock to a user. The image formed by a concave mirror is observed to be virtual, erect and larger than the object.
Question 3: Distinguish between conventional current and electronic current. The fourth unit has three chapters in it. Find notes, question papers for subjects like Mathematics, Physics, Biology, Chemistry and various competitive exams as well. Since water is optically denser than air, a ray of light entering from air into water will bend towards the normal. पेज 222 के उत्तर 10 Science Chapter 12 Electricity Intext Question answers given on Page 222 are given below. The solutions will provide an overview of the complete chapter bringing the key ideas into a clear perspective. Light enters from air to glass having refractive index 1.
Chapter 12 - Electricity There are eighteen questions in the chapter. The eighth chapter deals with reproduction activities in unicellular and multicellular organisms. The improvement of the website and its contents are based on your suggestion and feedback. In the fifth chapter, we will learn about the classification of elements and their evolution. Field lines are shown closer together where the magnetic field is greater.
Hence, current flowing through the 2 Ω resistor is. Unlike regular classroom tuitions, a student can learn at his own pace irrespective of time and place at Dronstudy. For other answers please visit to or or or or or or or go for Solutions. In the seventh question, we have to make diagram of to show how hypermetropia is corrected. The resistances are connected in series. Let the new resistance be R ' and the new amount of current be I '. Chapter 15 - Our Environment There are nine questions in the chapter of which first three questions are of objective type.
It is equal to the ratio of the potential difference applied across the conductor to the current flowing through it. Status, recession proof employment, higher pay scale, etc are some of the perks associated with a career in science. All Chapter 1 - Chemical Reactions and Equations Exercise Questions with Solutions to help you to revise complete Syllabus and Score More marks. Aluminium oxide and zinc oxide show the properties of both basic as well as acidic oxides. Is the prescribed lens diverging or converging? Chapter 2 - Acids, Bases and Salts The exercises contain total fifteen questions of which first four are of objective type. If the bulb is operated on 110 V, then the energy consumed by it is given by the expression for power as Therefore, the power consumed will be 25 W.
A cell generates a potential difference across its terminals. An ammeter is always connected in series in a circuit, so that entire current, which we wish to measure, flows through it. Thicker the wire, lower is the resistance of the wire and vice-versa. For other answers please visit to or or or or or or or go for Solutions. In a student life, 10th competitive exam is a significant phase. Chapter 8: How do Organisms Reproduce? Go back to main page or move to of page. In the tenth chapter, we will learn about light and its phenomena reflection and refraction in a detailed manner.
