Therefore at high temperatures the resistance of an insulator can FALL, and in some INSULATING MATERIALS, quite dramatically. In a material where the resistance INCREASES with an increase in temperature, the material is said to have a POSITIVE TEMPERATURE COEFFICIENT.Explanation:plz lik

Malleability and ductility are related. A malleable material is one in which a thin SHEET can be EASILY formed by hammering or rolling. In other WORDS, the material has the ability to deform under compressive stress. ... In CONTRAST, ductility is the ability of a solid material to deform under tensile stress.Explanation:follow, like, mark me as brainlist

ANSWER IS 3) HEAT conductivity.Explanation:By heat conductivity COPPER is USED to make cooking UTENSILS.

tion:(A) : Initial speed of the CAR A u=52 KMH −1 =52× 185 =14.44 ms −1 The car stops in 5 seconds i.e v=0 at t=5(A) : Initial speed of the car A u=3 kmh −1 =3× 185 =0.83 ms −1 The car stops in 10 seconds i.e v=0 at t=10With the help of these initial and FINAL points for both the cases, we can PLOT the graph of speed vs time.Area under the speed-time graph gives the distance covered.∴ Distance covered by car A x A = 21 ×14.44×5=36.1 m∴ Distance covered by car A x B = 21 ×0.83×10=4.15 mThus car A travels more distance than B.solution

nt Types of Natural Resources:There are many ways of classifying these natural resources. They can be biotic or abiotic(that is derived from organic materials or inorganic materials). Another way of classification of resources is by the AMOUNT of resource available for human consumption. Through this, resources can be classified into exhaustible and inexhaustible natural resources.1. Inexhaustible Natural Resources:Nature has blessed us with an unlimited supply of resources such as air, water and sunlight. These resources are called inexhaustible resources. They are also called renewable resources.2. Exhaustible Natural Resources:As the human POPULATION is increasing at an astounding rate, we have REACHED a number of 7.4 billion today! Naturally, this means that we are utilizing more and more natural resources. If we go at this rate, we will soon reach a day when nature will not be able to provide us with resources such as plants and trees, animals, mineral ores, fossil fuels such as COAL, petroleum and natural gas. Thus, these resources are exhaustible. These resources are called exhaustible or non-renewable resources.If the use of these resources is not monitored carefully, there will be no food for our predecessors to eat, no energy for them to power their machines and no material for them to build a shelter with. This is why it is important to understand which resources are exhaustible and which are not, and to practice sustainable development. This is nothing but the development that meets the needs of the PRESENT generations without compromising the ability of future generations to meet their own needsmake as brainlist

Decomposers are the organisms LIKE BACTERIA that break down the dead and decaying matter of plants and animals into simpler substances which GET mixed with the soil and can be used as NUTRIENTS by the plants. In this way, both scavengers and decomposers help to KEEP our surroundings clean.

tic cells have a true nucleus and membrane-bound organelles like mitochondria, Golgi COMPLEX, etc. The cell organelles and nucleus is embedded in the cytoplasm. The cell is covered with the plasma membrane. They have rod-shaped chromosomes, inside the nucleus which is covered by a nuclear membrane. They contain DNA as the genetic material and proteins in the nucleoplasm. The nuclear membrane is continuous with the endoplasmic reticulum. Mitochondria are called the powerhouse of the cell as it synthesizes energy-rich molecule ATP. The endoplasmic reticulum (ER) carries out modification of proteins and synthesis of lipids. There is TWO type of ER, namely ROUGH ER and smooth ER. Rough ER has ribosomes on its membrane. Golgi apparatus carries out sorting, tagging, packaging, and distribution of lipids and proteins. Peroxisomes carry out oxidation reactions that BREAK down fatty acids and amino acids. Vesicles and vacuoles are storage organelles. Apart from these organelles, the animal cell contains lysosomes and centrosomes. Plant cells have a cell wall and plastids like CHLOROPLAST which are absent in animal cells. mark ❤️

Molecular structureExplanation:All matter is composed of BASIC elements that cannot be broken down to substances with different chemical or physical properties. Elements are substances consisting of ONE type of atom, for EXAMPLE Carbon atoms make up diamond, and ALSO graphite. PURE (24K) gold is composed of only one type of atom, gold atoms.

Mendel conducted the EXPERIMENTS using Pisum sativum or pea PLANT.He selected homozygous tall (TT) and dwarf (tt) pea plants.He crossed the tall pea plant with the dwarf pea plant.It was OBSERVED that the  F1 GENERATION are all tall plants.Thus, it was concluded that the gene causing tallness is dominant while the gene causing dwarfness is recessive.The trait expressing itself in the hybrid is the dominant one. This experiment proves Mendel’s first law of inheritance.It states that when a pair of contrasting factors is brought in a hybrid, one factor inhibits the appearance of the other, one which inhibits is the dominant one and which is INHIBITED is recessive.Explanation:hope its helpful. please mark me as brainliest and follow me

Which ONE of the FOLLOWING ELEMENTS has no neutron?hydrogen EXPLANATION:Which one of the following elements has no neutron?hydrogen

your answer................A pith ball hangs vertically by a thread. A plastic rod is CHARGED by rubbing with cloth. The charged rod is brought close to the pith ball without touching it. It is OBSERVED that the charged rod weakly attracts the pith ball. This may be surprising – and you are right to be surprised, for the pith ball carries no charge. For the time being we are going to put this observation to the back of our minds, and we shall defer an explanation to a later chapter. Until then it will remain a small but insistent little puzzle.We now touch the pith ball with the charged plastic rod. Immediately, some of the magical property (i.e. some of the electric charge) of the rod is transferred to the pith ball, and we observe that thereafter the ball is strongly repelled from the rod. We conclude that two electric charges repel each other. LET us refer to the pith ball that we have just charged as Ball A.Now let’s do exactly the same experiment with the glass rod that has been rubbed with silk. We bring the charged glass rod close to an uncharged Ball B. It INITIALLY attracts it weakly – but we’ll have to wait until Section 3.6 for an explanation of this unexpected behavior. However, as soon as we touch Ball B with the glass rod, some charge is transferred to the ball, and the rod thereafter repels it. So far, no obvious difference between the PROPERTIES of the plastic and glass rods.But... now bring the glass rod close to Ball A, and we see that Ball A is strongly attracted. And if we bring the plastic rod close to Ball B, it, too, is strongly attracted. Furthermore, Balls A and B attract each other.We conclude that there are two kinds of electric charge, with exactly opposite properties. We arbitrarily call the kind of charge on the glass rod and on Ball B positive and the charge on the plastic rod and Ball A negative. We observe, then, that like charges (i.e. those of the same sign) repel each other, and unlike charges (i.e. those of opposite sign) attract each other. ............hope it helps youtc

तत्वों की संयोजन शक्ति (COMBINING POWER) को संयोजकता (VALENCY) का नाम दिया गया है। संयोजकता का यथार्थ ज्ञान ही समस्त रसायन शास्त्र की नींव है। पिछले वर्षो में द्रव्यों के स्वभाव तथा गुणों का अधिक ज्ञान होने के साथ साथ संयोजकता के ज्ञान में भी वृद्धि हुई है।दूसरे शब्दों में, संयोजकता एक संख्या है जो यह प्रदर्शित करती है कि जब कोई परमाणु कितने इलेक्ट्रॉन प्राप्त करता है, या खोता है या साझा करता है जब वह अपने ही तत्व के परमाणु से या किसी अन्य तत्व के परमाणु से बन्धन बनाता है।

When an acid REACTS with METAL, a salt and hydrogen are produced: acid + metal → salt + hydrogen An example: nitric acid + calcium → calcium nitrate + hydrogen The salt that is produced DEPENDS UPON which acid and which metal react.

PH IN DIGESTIVE SYSTEM - DEFINITIONThe pH in the human digestive tract varies greatly. The pH of saliva is usually between 6.5 - 7.5. The fundic or upper portion of the stomach has a pH between 4.0 - 6.5, lower portion of the stomach secrete hydrochloric acid (HCI) and pepsin until it reaches a pH between 1.5 - 4.0.PH IN GROWING CROPS - DEFINITIONpH is a scale that chemists use to measure acidity. Values below 7 are CONSIDERED acidic, values above 7 are alkaline ( the opposite of acidic) and 7 is neutral. Most plants can tolerate a wide pH range in solution culture, but they cannot tolerate a wide range of acidity in the soil.EFFECT OF PH ON TOOTH DECAY - DEFINITIONThe saliva in a healthy mouth has a pH of 7.1. Certain foods increase the acidity of the mouth and reduce the pH level. Saliva helps neutralize the acid, but the pH of saliva can become more acidic after eating acidic foods. It can take between a few MINUTES to a few hours for the pH of the mouth to neutralize. In that time, the lower pH of the mouth creates an optimal environment for bad bacteria, which eventually causes tooth decay.EFFECT OF PH ON PLANTS AND ANIMALS - DEFINITIONHigh levels of either acidity or alkalinity can be harmful to plants and animals.Effect on Plants:Most of the plants do best when soil'd pH is in the neutral range i.e. 6 to 7.Acidic soil can prevent certain nutrients from being ABSORBED by plants that are best absorbed in alkaline soil. In very alkaline soil, certain important micro-nutrients such as zinc and copper become chemically unavailable to plants.Effect on Animals:Effect of pH is most observed for the animals that stay in water. Acidic water ROBS fish and other aquatic species of sodium in the blood and oxygen in the tissues. Additionally, it affects the functioning of fish GILLS. Acidic water also poisons fish eggs, as they will not hatch if water pH is too low.In addition to the direct effects on fish, acid water also destroys ecosystems by killing organisms lower on the food chain.
