A medium which has the HIGHEST REFRACTIVE index will have the highest optical density and vice-versa. It can be OBSERVED from table 10.3 that DIAMOND and air respectively have the highest and LOWEST refractive index. Therefore, diamond has the highest optical density and air has the lowest optical density.

Quantum theory is the fundamental theory in Physics ehich describes nature at the smallest scales of ENERGY LEVEL of ATOMS and SUBATOMIC theories..

Energy TRANSFORMATION in moving a fan is- a SIGNIFICANT PROPORTION of electric energy converts into kinetic energy while some electric energy converts into heat energy with time.hope it HELPS you!!Mark as brainliest√

hey!! here is your answer :There are a number of ways to REDUCE FRICTION:✴Make the surfaces smoother.✴Lubrication is another way to make a surface smoother.✴Make the object more streamlined.✴Reduce the FORCES acting on the surfaces.✴Reduce the CONTACT between the surfaces.✴Roll the bodies instead of SLIDING them✔hope it helps u ✔✔

770Explanation:mass=8m/stime=0smomentum(P)=m×vp=5×8=40 Now, change in TIME v=(101+61)v=162m/s p=m×v p=5×162 p=810 CHAMGE in p 810-40 770

tance travelled by the stone in the nth second is GIVEN by,SN=u+a/2(2n-1)here u=o so Sn=a/2(2n-1)if N is last second then,Sn is equals to first five seconds S=ut+1/2a(t)2   =1/2a25=25a/21/2a(2n-1)=25a/2=by solving this we get n=13 seconds 13th second is the last second. So, the stone will remain in air for 13 seconds. HOPE this helps, Keep posting and have a nice day!

increased by 4 timesExplanation:F₁=Gm₁m₂/R²F₂=Gm₁m₂/(R/2)²    =Gm₁m₂/(R²/4)F₁:F₂= Gm₁m₂/R²: Gm₁m₂/(R²/4)after cancelling on both sides we get,F₁:F₂ = 1:4therefore,the value of F increases by 4 times or in other WORDS, increased by 400%.hope it HELPED and pleeeease mark as brainliest:)

How Can a Given POTENTIOMETER Be MADE More Sensitive? Concept: ... (ii) In the graph shown below for two POTENTIOMETERS, state with reason which of the two .EXPLANATION:

Characteristics of concave mirrorCharacteristics of concave mirrorConcave mirrors can PRODUCE both real and VIRTUAL IMAGES; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real); they can ALSO be enlarged, reduced, or the same SIZE as object. 2. ... A plane mirror will always produce an upright image

i GUESS the ANSWER is W/4

Most metals can't resist NATURAL processes like oxidation, CORROSION, etc. Hence, only non-reactive metals like gold, silver, platinum, etc are found in the native or free state. ... The process of procuring metals from ores is called METALLURGY and these naturally occurring compounds of metals are known as minerals.

hey mate here is your ANSWER :The advantage of the COILED coil is that evaporation of the tungsten filament is at the rate of a tungsten cylinder having a diameter EQUAL to that of the coiled coil. The coiled-coil filament evaporates more slowly than a straight filament of the same surface AREA and light-emitting power.hope it helps U ✔✔✔✔✔✔☺☺
