annot be created or destroyed.ATOMS cannot be broken down into smaller pieces. All atoms of an element are identical. Chemical reactions CAUSE atoms to be REARRANGED

n is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.[2] There are several types of friction:Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into static friction ("stiction") between non-moving surfaces, and kinetic frictionbetween moving surfaces. With the exception of atomic or MOLECULAR friction, dry friction generally arises from the interaction of surface features, known as asperitiesFluid friction describes the friction between layers of a viscous fluid that are moving relative to each other.[3][4]Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces.[5][6][7]Skin friction is a component of drag, the force resisting the motion of a fluid across the surface of a body.Internal friction is the force resisting motion between the elements MAKING up a solid material while it undergoes deformation.[4]When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into thermal energy (that is, it converts WORK to heat). This property can have dramatic consequences, as illustrated by the use of friction created by rubbing pieces of wood together to start a fire. Kinetic energy is converted to thermal energy whenever motion with friction occurs, for EXAMPLE when a viscous fluid is stirred. Another important consequence of many types of friction can be wear, which may lead to performance degradation or damage to components. Friction is a component of the science of tribology.

n't hear an echo in small room because in it the sound can't be REFLECTED back. For an echo of a sound to be heard,the minimum DISTANCE between the SOURCE of sound and the walls of the roomshould be 17.2 m.Obviously,in ASMALL room echoes cannot beheard.

entimeterscc stands for cubic CENTIMETERS, a unit of VOLUME. So 1500 cc is essentially 1.5 litres. This number basically is APPROXIMATELY (usually less than 1.5L but it is rounded off) the displacement volume of the engine i.e. the volume covered by the stroke of the piston MULTIPLIED by the number of cylinders the engine has.mark as BRAIN list

y takes PLACE when both of the FOLLOWING two CONDITIONS are met:the light is in the more dense MEDIUM and approaching the less dense medium.the angle of incidence is GREATER than the so-called critical angle.

station, ALSO referred to as apower plant or POWERHOUSE and sometimes generating station or generating plant, is an industrialfacility for the generation of electricpower. ... Others USE nuclear power, but there is an increasing use of cleaner RENEWABLE SOURCES such as solar, wind, wave and hydroelectric.

ng to newton's second law of MOTION mass is inversely PROPORTIONAL to acceleration. So if mass is more acceleration is less and viceversa. Similarly the mass of stone is LESSER than that of earth and hence we see the stone FALL not earth move

.❤❤❤here is UR answer...Radius of GYRATION or gyradius of a body about an AXIS of rotation isdefined as the radial distance of a point from the axis of rotation at which, if whole mass of the body is assumed to be concentrated, its moment of inertia about the given axis would be the same as with its actual distribution of mass.Mathematically the radius of gyration is the root mean SQUARE distance of the object's parts from either its center of mass or a given axis, depending on the relevant application. It is actually the perpendicular distance from point mass to the axis of rotation.hope it HELPS...plzz mark me as brainliest my dear !!!❤❤❤

ens because sun rays bends slightly TOWARDS the earth surface when it is below the horizon due to the presence of various layers of atmosphere which refracts the the sunlight in various amounts towards the earth surface...This is because of the refraction of the light from the Sun by the Earth's atmosphere--the Earth's atmosphere bends the PATH of the light so that we see the Sun in a position slightly different from where it really is. The magnitude of this effect varies with latitude, but it's strongest at the equator, where the Sun rises 2 minutes earlier than it would if the Earth had no atmosphere, and SETS 2 minutes after it would if the Earth had no atmosphere.

nal motion is just like the motion that we are studying till now .SUPPOSE we DEFINE force as F in rotational motion is defined by T(torque) as the name suggest it deals wirh the body in rotation .you will study about OMEGA, then alpha Then mass as moment of inertia .And lots of things. theres no end of this .In simple it means studying body which is in rotation . I have not explained so effectively you can READ in hcv or any other book.Hope you like it.

ctrons of a mettal can be considered to form a FARMI gas.the number density of conduction electrons in METALS ranges between approximately 10^28 and 10^29 electrons/m^3, which is also TYPICAL density of atoms in ORDINARY solid matter.

ssume the voltage is 240 volts and the current FLOWING is100 amperes then 240 volts TIMES 100 amperes EQUALS 24,000 watts.

your answer mate ↙️↙️↙️✅✅✅✅ DISTANCE = 1) it is defined as the rate of change of speed.2) it is a scalar quantity.3) it can NEVER be NEGATIVE or ZERO.4) Distance MAY or mat not be equal to velocity.VELOCITY = 1) it is defined as the rate of change of displacement.2) It is a vector quantity.3) It can be negative,zero or positive.4) A body may possesses different velocities but the same distance.Hope this helps you dude all the best ☺️☺️✌️✌️✌️

e the ATMOSPHERIC pressure , ρ be the density of liquid and v be the velocity of fluid coming out of orifice of a container. Depth of orifice from free SURFACE is h and TOTAL depth till bottom is H. Pressure of liquid at free surface and orifice is atmospheric and has nothing to do with horizontal velocity coming out of orifice. Liquid coming out has both KINETIC energy and potential energy while liquid at free surface has only potential energy.According to Bernoulli's theorem , sum of pressure and total energy per UNIT volume at surface and every point of orifice is constant.p+0+ρgH = P+ρv2/2 + ρg(H-h)Since potential energy of free surface has to convert to kinetic energy of motion.ρgH = ρv2/2Now solve for v.

e Density is the ratio of a density of a substance to the density of water at 4°C. So mathematically, RD = Density of a substance ÷ Density of water at 4 ° C RD= Mass of a substance ÷ Mass of same VOLUME of water at 4°C RD = Weight of a substance ÷ Weight of same volume of water at 4°C Using a RD Bottle, (M3 - M1) ÷ (M2 - M1). Where M1 is the mass of empty bottle, M2 is the mass of bottle + water, M3 is the mass of bottle with the required liquid Using Archimedes Principle (Weight of body in air) ÷ ( Weight of body in air - Weight of body in water) (Weight of body in air ÷ { Weight of body in air - Weight of body in liquid other than water}) × RD of that liquid The above two calculations of RD is done based on the principle of buoyancy , Archmides principle and Law of FLOATATION. It STATES that the loss of weight in a body when immersed in a liquid is equal to the weight of the liquid displaced by the body. Up thrust = Loss in weight = = Vol of liquid displaced× Density of liquid × ACCELARATION due to gravity = Mass of liquid displaced× Accelaration due to gravity = Weight of the liquid displaced

s or SOFTNESS is DETERMINED by its amplitude. The amplitude of wave is higher that sound become LOUDER sound . The amplitude of the wave is LOWER that sound become softer sound.

e PRETTY tough to shave! Or find that annoying mole on your back! This MEANS either we'd be extremely reliant on others or would lose some interest in these tasks.   The world might shed some of the vanity we are so absorbed with in the 21ST century, and free our erstwhile pre-occupied minds to other tasks. This would of course lead our civilization in a whole other direction. With less (it would still be there to some extent) emphasis on SUPERFICIAL beauty and more on perhaps knowledge or other useful skills. However, at the end of the day we are hard-wired to make judgement calls on first appearances, and even though the contribution of outer beauty would have decreased it would still play a PART. Hence every house would definitely have had large containers of water, until of course technology and the selfie-generation came about!
