because of their BRIGHT shiny surface and HIGH resistance to corrosion also they have high malleability and DUCTILITY

Explanation:Two wires X and Y are of equal length and have equal resistances. X - R₁   & Y - R₂R₁ = ρ₁ L₁ /A₁R₂ = ρ₂ L₂ /A₂R₁ = R₂ L₁ = L₂ = L=> ρ₁ L /A₁ = ρ₂ L /A₂=> ρ₁  /A₁ = ρ₂  /A₂=>ρ₁/ρ₂  = A₁ /A₂ρ₁ > ρ₂=> A₁ > A₂Wire X is thickerWhile Diluting an acid , if we ADD water in acid then it will make very much concentrated acidic solution which may boil and cause harm to the person performing actions.Thats why acid is added in water You have four solutions A, B, C and D. The pH of solution A is 6, B is 9, C is 12 and D is 7.The pH scale ranges from 0 to 14. pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic.A is most acidicC is most basic

Current is the NET flow of charged PARTICLES. It's measured in AMPERES. Current is modeled as the flow of positively charged particles, so that if electrons flow from B to A, convention STATES that current flows from A to B. This is the convention because Benjamin Franklin decided it a few centuries AGO. 1 A * 1 s = 1 C1 C * 1 electron / (1.6 * 10^-19 C) = 6.25*10^18

(i)(a) White Silver Chloride turns grey in the sunlight because of photochemical decomposition. In sunlight Silvel Chloride (AgCl₂) is decomposed into Silver (Ag) and Chlorine gas2AgCl₂ → 2Ag + 2Cl₂(b) Brown coloured Copper powder on heating in air turns into black coloured substance as Copper reacts with atmospheric Oxygen and FORMS Copper Oxide (CuO) which is black in colour. The reaction is gives as:2Cu + O₂ → 2CuO(ii)(a) Displacement Reaction: Displacement reaction is a chemical reaction in which a more reactive ELEMENT displaces a less reactive element from its compound. Example - Reaction of Iron with Copper Sulphate SOLUTION is an example of displacement reactionFe + CuSO₄ → Cu + FeSO₄(b) Reduction Reaction : A chemical reaction where either Hydrogen is ADDED to or Oxygen is removed from a compound. Example-H₂ + F₂ → 2HF(c) Combination Reaction: A reaction where two or more substances or compounds combine to form a SINGLE compound or product. Example-C + O₂ → CO₂

this ANSWER is CORRECT

Fundamentals is INDIA are known as fundamental crystal YAARR..PLZ FOLLOW

For any circuit element, the power is EQUAL to the voltage difference across the element multiplied by the current. By Ohm's Law, V = IR, and so there are additional forms of the electric power formula for resistors. Power is MEASURED in UNITS of Watts (W), where a WATT is equal to a Joule PER second (1 W = 1 J/s).

hey MATE REPOST your QUESTION with a diagram....so i can see the diagram and ABLE to help you dear mate....✔✔

1) When dilute HCl is added to solid Na2CO3,then a CHEMICAL reaction takes place to form a salt,Sodium Chloride(NACL),WATER and Carbon Dioxide.(which is produced inthe form of brisk effervescence).Explanation:It is actually one of the properties of acids.When a dilute ACID reacts with metal carbonates or metal HYDROGENCARBONATES,then a salt,water and Carbon Dioxide Gas is formed.CO2 is formed in the formed of brisk effervescence.The presence of CO2 can be tested by passing the gas formed through lime water.If it turns milky,then the gas is CO2

Explanation:PEDUNCLE: This is the stalk of the flower.Receptacle: It is that part of the flower to which the stalk is attached to. It is small and found at the centre of the base of the flower.Sepals: These are the small, leaf-like parts growing at the base of the petals. They form the outermost whorl of the flower. Collectively, sepals are known as the calyx. The main function of the calyx and its sepals is to protect the flower before it blossoms(in the bud stage).Petals: This layer lies just above the sepal layer. They are often BRIGHT in colour as their main function is to attract pollinators such as insects, butterflies etc to the flower. The petals are collectively known as the corolla.Stamens: These are the male parts of a flower. Many stamens are collectively known as the androecium. They are structurally divided into two parts:Filament: the part that is long and slender and attached the anther to the flower.Anthers: It is the HEAD of the stamen and is responsible for producing the pollen which is transferred to the pistil or female parts of the same or another flower Pistil: This FORMS the female parts of a flower. A collection of pistils is called the gynoecium.

tion:Artificial satellites are used to STUDY the Earth, other planets, to help us COMMUNICATE, and even to observe the distant Universe. Satellites can even have people in them, like the International SPACE Station and the Space Shuttle. ... Satellites are launched into different orbits depending on their mission.

stible resources are a resource that is PRESENT with unlimited AMOUNTS in the nature; they cannot be depleted or exhausted by human activity.Examples: Air, WATER, sand CLAY, SOLAR energy e.t.c

Combination reaction types:1. Reaction between two elementsEx: C + O2`->` CO2Here the carbon is completely burnt in oxygen which results in carbon dioxide 2. Reaction between two compoundsEx: CaO + H2O `->` Ca ( OH)2Here the CALCIUM oxide (lime) combined with WATER gives calcium hydroxide which also known as slaked lime.3. Reaction between an element and compoundEx: O + H2O `->` H2O2Here oxygen which is an element combined with water which is a compound gives hydrogen peroxide.Examples for combination reaction:1. Na2 + H2O `->` 2NaOHHere sodium oxide is combined with water gives sodium hydroxide.2. 4Li + O2 `->` 2Li2OHere lithium is combined with oxygen to form lithium oxide.3. 2Mg + O2 `->` 2 MgOHere magnesium is combined with oxygen to form magnesium oxide.4. H2 + Cl2 `->` 2 HCLHere hydrogen is combined with chlorine to form hydrochloride.5.

Negative acceleration is the acceleration in the OPPOSITE direction which change the velocity by decreasing the magnitude of velocity that is delat (v) is always -v .The negative acceleration known as retardation .2 .Average velocity of an object is it's total DISPLACEMENT divided by total time taken . In other WORDS it is the rate at which an object change its POSITION from one place to another . Average velocity is the vector quantity .3. The average speed of an object is the total distance covered by a body divided by the elapsed time to cover that distance . It's scalar quantity which means it is defined only by magnitude .Explanation:Hope this ANSWERS will help you#Follow me ✌️

if potassium kept open they can burn and if they kept in WATER they can REACT with water so they kept in kerosene . potassium is most reactive metal on this earth they react very explosively with both water and air that is why it is stored in kerosenephosphorous catches FIRE if exposed to air and to PREVENT the contact with atmospheric oxygen it is stored in water..Explanation:# follow me

ocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's SPEED and direction of motion (e.g. 60 km/h to the north).

Work done on an OBJECT is the PRODUCT of FORCE applied and the DISPLACEMENT covered in the direction of force applied. ... Hence, the work done in auniform circular motion is always zero. In circular motion θ is 90° hence work done by force is zero.

Total ENERGY at initial position = K.E + P.E = 0 + mghTotal energy when it REACHES the ground = K.E + P.E = 0.5mv^2 + 0VELOCITY when it reaches the ground = sqrt(2gh)Substitute velocity in total energy equationTotal energy when it reaches the ground = 0.5mv^2 = 0.5m * 2gh = mghWe found that total energy when it reaches the ground = Total energy at initial position.In other words, KINETIC energy with which it hits the ground is the transformation of its initial potential energy.Ok nancy you can SLEEP now bye

behind the usage of purified air or compressed air as lubricants, are:1) Various equipments are extremely sensitive to the liquid substances and can get damaged if the equipments get in contact with the liquid substances.In this situation the air based lubricants are the best solution.2)The air based lubricants are mainly generated by machines which is one TIME INVESTMENT but the NORMAL liquid lubricants are needed to be PURCHASED everytime when we need them after the previous usage.
