in g/cm3 = 0.65To change g/cm3 to KG/M3 multply the NUMBER by 1000that is 0.65×1000= 650kg/m3So the answer is 650 kg/ m3

No.The ELECTRICIAN cannot be allowed to REPLACE the fuse in the house by a piece of wire. This is because EVERY wire cannot be used as a fuse FILAMENT. A fuse filament must have a low melting point such that it could melt and break in response of large amount of current. Most of the wires have high melting pointshope it helps you......

1 ML = 10⁻⁶ m³Hence 80 ml = 80 × 10⁻⁶ m³Pressure = 100 mm of HgBut we must have the Pressure in Pascals.760mm of Hg  = 1.01 × 10⁵ PA⇒ 100 mm of Hg = 1.01 × 10⁵ Pa / 760 = 132.89 PaNow we know that Power = Work Done / TimeWork Done = Pressure × Change in Volume⇒  Work Done = 132.89 Pa × 80 × 10⁻⁶ m³⇒  Work Done = 10631.2 × 10⁻⁶ JTime = 60 sec / 60 sec = 1⇒ Power = 10631.2 × 10⁻⁶ J = 1.06 W Since there is no such option, we TAKE the closer value of 1.07 W as the answer.Option (A) is correct.Thanks !!

ion occurs because the refraction of different colours is different ..... HENSE the REFRACTIVE INDEX of the medium is the largest for the violet colour and least colour is red colour .--------❤️Thanks ----------❤️

s, or VOLUME, is the way that the human EAR perceives SOUND. At its SIMPLEST, when the amplitude is increased, sound gets LOUDER, and when it is decreased, sound gets quieter.

is an element which shows the oxidation state of 4 which COMBINED with its property of catenation, makes it possible to form a HUGE number of compounds. Catenation is the property by which it can make bonds with other CARBON atoms to form long chains.

rm magnetic field is such in which the magnetic field are evenly DISTRIBUTED providing an equal or SIMILAR STRENGTH of magnetic field irrespective of the POSITION the OBJECT placed

for COMBUSTION (fire) oxygen is NEEDED and when carbon dioxide is there instead of oxygen, then the process of combustion can't CONTINUE. So carbon dioxide is considered as a BEST fire extinguisher

end!The air pressure inside the JET plane is much higher than the air pressure OUTSIDE.   If the window breaks due to an accident the air pressure inside the plane is REDUCED causing a sudden drop in air pressure inside the jet plane.Thus it affects our lungs and we couldn't breathe unless we breathe with the help of an oxygen MASK or cylinder.Hope it helps : ))

your answer BRO. If you have any CONFUSION then look for the DIAGRAM in the NCERT SCIENCE textbook as well.

l pentane is a branched chain ALKANE with the molecular FORMULA C6H14.It is a structural isomer of hexane composed of methyl group bonded to the THIRD CARBON ATOM in a pentane chain. HOPE THIS HELPS YOU ✌

rential MAGNETIC FIELD is a magnetic field which is VARYING CONTINUOUSLY.

th coil and magnet are stationary, there is nocurrent induced and HENCE there is no DEFLECTION in GALVANOMETER connected to COOL. HOPE THIS HELPS YOU ✌

rential MAGNETIC FIELD is a magnetic field which is VARYING CONTINUOUSLY.

il of wire is placed in a changing magnetic field,a CURRENT will be induced in the wire. The direction of the magnetic field, the current induced and the direction of force on CONDUCTOR are perpendicular to each other and can be FOUND using Flemming's right hand RULE

coilnand MAGNET are STATIONARY, there is no deflection in the galvanometer as no CURRENT is INDUCED.

wer is called TECTONIC shift.The earth's SURFACE is in the form of plates called tectonic plates.There are seven MAJOR plates forming the seven continents. Tectonic shift-The movement of the plates causes earthquakes and volcanoes.- There are four types of movement1. COLLISION- occurs when the moving two plates collide with each other usually resulting in mountains.2. SUBDUCTION - is the movement of one plate moves below the other and it sinks down.3. Spreading - is the movement of the two plates away from each other.4. Transform faulting - is the movement of the plates, where the two plates slide past one another.

e test tubes contain TRUE solutions.  The potash ALUM and the SALT are completely soluble in WATER. So the test tubes a and b are true solutions.  True solutions: These are homogeneous solutions in which the solute is completely dissolved in the solvent. In true solutions, the light rays pass through it, when a beam of light is passed.  Therefore when the light is passed through both the beakers a and b, the PATH of light is visible but is not scattered.

ray is REFRACTED (BENT) when it PASSES from ONE medium to another at an angle and its speed changes. ... Because white LIGHT is made up of ALL visible wavelengths, its colors can be separated (dispersed) by this difference in behavior

ing WAVE is REPRESENTED by y = asin(100t)cos(0.01x), where y and a are in millimetres, t is in sec and x in metres.The velocity of wave .we KNOW if standard equation of STANDING wave is given by, then, velocity of wave is in given equation, = 100and = 0.01 so, velocity of wave = 100/0.01 = 10⁴

re of CESIUM chloride is body centre cubic TYPE in which Cs+ placed within centre and Cl- placed at corner of lattice. number of Cl- ions PER unit CELL = 8 × 1/8 = 1 number of Cs+ ions per unit cell = 1 so, there is only one molecule of CsCl in a lattice .so, mass of one molecule of CsCl = MOLAR mass of CsCl/Avogadro's number= (133 + 35.5)/(6.023 × 10²³) = 168.5/6.023 × 10²³ = 2.8 × 10^-22 g volume of lattice = a³ , where a is edge length= (412.1 × 10^-12)³ = 7 × 10^-23 cm³ so, density of CsCl crystal = 2.8 × 10^-22/7 × 10^-23 = 4 g/cm³

as different properties one the properties include refraction ,reflection ,speed or VELOCITY among OTHERS refractive E INDEX is the refractive power of an object ,different MEDIUM have different refractive index .for example that of water is different from that of air or oil or any other medium .water for example have a refractive index of 1.33 refreactive index is therefore the ratio of the speed of light in a medium compared to the speed of light in another medium .a medium like glass has a refractive index of 1.57

Thin convex lensesStep by step explanation:For convex LENSES with a big thickness, this means that the light rays travel inside them for a LONGER period of TIME. As a CONSEQUENCE, the the light rays are bent more in the thick convex lenses. As the BENDING of light rays increases, the focal length decreases. Hence, thin convex lenses have a higher focal length.

paratus can be USED to SHOW that the DENSITY of WATER is MAXIMUM at 4° C.

c heat of water is = 4.2 J/(g.K)SPECIFIC heat of ICE is = 2.1 J/(g.K)Latent heat of ice is = 336 J/gHeat released by 10 g of water at 10°C in converting to water at 0°C is,H1 = msθ = (10)(4.2)(10) = 420 JHeat gained by 10 g of ice at -10°C in converting into ice at 0°C is,H2 = (10)(2.1)(10) = 210 JSuppose, ‘x’ g of ice now melts. So, heat gained by this ‘x’ g of ice in converting into water at 0 oC is,H3 = xL = x336 = 336x JNow, H3 + H2 = H1=> 336x + 210 = 420=> x = 0.625 gMass of ice remaining is = 10 – 0.625 = 9.375 gThus, in the resulting mixture the ice remaining is 9.375 g and the TEMPERATURE of the mixture is 0°C.

estion is incomplete . A complete QUESTION is ​-----> How many degrees of FREEDOM do the molecules of a gas have if the density at ntp is 1.3 kg/m³ and velocity of sound is 330 m/s ?solution : use the formula, where v is velocity of sound , i is degree of freedom, P is ATMOSPHERIC pressure and is density of gas. now, or, or, or, hence, i = (2 × 10^5)/(330 × 330 × 1.3 - 10^5) ≈ 5hence, degree of freedom is 5

can be characterized by the following three quantities: (i) PITCH. Pitch is the frequency of a SOUND as PERCEIVED by human ear. A high frequency gives RISE to a high pitch note and a low frequency produces a low pitch note.
