its called dispersion of light

The splitting of white light into different colours is called dispersion of light .

Dispersion of light-splitting of white light in seven colours

Dispersion of light it disperses into its component colours

why you can post the example this app can help the question only

Tq

White light can be split into seven colors, namely, red, orange, yellow, green, blue, indigo and violet. The colors can be remembered using the acronym VIBGYOR

White light consists of the visible light colors in the electromagnetic spectrum. The electromagnetic spectrum consists of waves of different wavelengths.

correct is VIBGYOR

(P + a/V^2) (V - b) = RTP is pressure, V is volume and T is temperature.[P] = [F/A] = [MLT^−2/L^2] = [ML^−1T^−2][V] = [L^3]We cannot add or subtract quantities of different dimensions. Therefore[P] = [a/V^2] ⇒ [a] = [PV^2] = [ML^−1T^−2L^6] = [M L^5T^−2]∴ [a] = [M L^5T^−2]Similarly,[b] = [V] = [L^3]

Focal length , f = 15 cm Object distance , u = - 60 cm Image distance, v = v

Lens formula 1/v - 1/u = 1/f

1/v - (1/-60) = 1/151/v +1/60 = 1/151/v = 1/15+1/601/v = ( 4 +1)/601/v = 5/60V = 12 cm

the process of burning is called combustion

combustion is a process of the burning of the substance

the process of burning something.

"the combustion of fossil fuels"

synonyms:burning,firing,kindling,igniting,ignition

"the combustion of fossil fuels"

rapid chemical combination of a substance with oxygen, involving the production of heat and light.

Acombustion reaction(commonly known as burning ) is an exothermicreactionin which something reacts with oxygen. Thecombustionof organic compounds usually takes the form organic compound + oxygen => water + carbon dioxide. ...Combustion reactionsare the classic one of the very most exothermicreactionwe can have.

angle of incidence=90°-50°=40°

Ray AB is incident normally as shown in fig. (a), so dispersion does not happen in the prism. But, the emergent beam gets dispersed.

In Fig. (b), dispersion occurs both inside and outside the prism as the ray is incident at an angle on the prism.

Like my answer if you find it useful!

The distance of diameter from the circle is 10 cm

we know a radius makes 90° angle on any chord and bisects it.so,radii=> 26/ 2 => 13 cm ( H )base=> 24/ 2 => 12 cm ( B )p= ?

H² = B² + P²13² = 12² + P²169 = 144 + P²P²= 169 - 144P² = 25P=√ 25P= 5cm

The distance of chord from the centre is 5cm.

2)When the incident Ray enters the glass slab it bents towards the normal as glass slab is denser than air . And when the Ray enters air again it bents away from the normal and parallel to the incident ray

a) It gives larger image and the nature of the image is real and invertedc) p=1/f p=10/50=-0.2D

Side = aSo two side is 2aNow it's in the shape of rectangleSo Diagonal = √2a^2 + a^2= √5aTotal distance traveled by ant is √5a

but a = 10m

so , total distance is 10√5

The permittivity of free space (a vacuum) is a physical constant equal to approximately 8.85 x 10-12farad per meter(F/m)

It's unit isC²N^-1M^-−2( coulomb squared per Newton per square meter).

Themagnetic fieldB is defined from the LorentzForceLaw, and specifically from themagnetic forceon a moving charge. The magnitude of theforceis F = qvB sinθ where θ is the angle < 180 degrees between the velocity and themagnetic field. So force experienced isF = qvB sinθ, where q is charge

437.5m is the correct answer

437.5 m is the correct answer

Thegreenhouse effectis the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere.

If a planet's atmosphere contains radiatively active gases (i.e.,greenhouse gases) they will radiate energy in all directions. Part of this radiation is directed towards the surface, warming it. The intensity of the downward radiation – that is, the strength of the greenhouse effect – will depend on the atmosphere's temperature and on the amount of greenhouse gases that the atmosphere contains.

Earth’s natural greenhouse effect is critical to supporting life. Human activities, mainly the burning of fossil fuels and clearing of forests, have strengthened the greenhouse effect and causedglobal warming.

The term "greenhouse effect" arose from a faulty analogy with the effect of sunlight passing through glass and warming agreenhouse. The way a greenhouse retains heat is fundamentally different, as a greenhouse works mostly by reducing airflow so that warm air is kept inside.

CFCscause ozone hole. These are degraded in the stratosphere in the presence of UV-radiation, releasing Cl atom. Cl atoms act as catalyst in the degradation of ozone releasing molecular oxygen

option(b) is correct

Ans :- The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere. If a planet's atmosphere contains radiatively active gases they will radiate energy in all directions.

Importance :-

It is important for us for maintaining the earth's atmosphere. Without it earth cannot be warm enough to support human life.

Of it increases too much means it increase the temperature on earth to much then it will disrupt sea level, weather etc.

1. TheLewis dot structure for sodiumis:Sodiumis in family IA, which means it has one valenceelectron. We represent this oneelectronwith a singledot surroundingsodium'satomic symbol.electronic configuration- 2 8 1

2.Magnesiumis in Group 2 (sometimes called Group II or 2A). Since it is in Group 2 it will have 2 valenceelectrons. When you draw theLewis structure for Magnesiumyou'll put two "dots" or valanceelectronsaround the elementsymbol(Mg).electronic configuration- 2 8 2

Theelectron dot diagramfor an element shows the valenceelectronsfor the element.Oxygenis in group 16/VIA, so it has six valenceelectrons.

i want the proper explanation anyways thanks

(d) 10mH is the answer i guess

the mutual inductance is given by √(L1*L2)here L1 = 2mH , and L2 = 8mH so, mutual inductance = √2*8 = √16 = 4mH.

option B.

Workcanbe completelyconvertedintoheat, but thereverseis nottrue:heatenergy cannot be whollytransformed intowork energy.

full explanation mil sakti hain kya

thank you

Muscular forceis theforceapplied using parts of the body like arms or legs. It isforcethat results due to the action of muscles, and is a contactforce, since there is a contact between the surfaces.Muscular forceis needed whenever movement of the body occurs. Walking, lifting

Arteries1. Arteries carry pure blood from the heart to supply all the tissues except for pulmonary artery.2. Arteries branch out to form capillaries which supply oxygenated blood to all the organs.3. Arteries have thick walls as blood in them flows under great pressure.4. Arteries do not have any valves in them.

Veins1. Veins carry deoxygenated blood to the heart and the lungs except for pulmonary veins.2. Veins are formed by many capillaries joining together to dump the deoxygenated blood from different tissues.3. Veins have thin muscular walls as blood in them flows under less pressure.4. Veins have valves in them to prevent backward flow of the blood.

Blood normally remains in its liquid state while it iswithinblood vesselsbut when it leaves them thebloodmay thicken and form a gel (coagulation). Blood clotting (technically "blood coagulation") is the process by which (liquid) blood is transformed into a solid state. The mechanism of blood clotting is a complex process involving many clotting factors (incl. calcium ions, enzymes, platelets, damagedtissues) activating each other.

1500 is the answer is correct

ab lol

mera bhi whi answer h

but option me nahi h

option me Kya h?????

1580

ans hi h

wrong answer.. didnt match in option

kcch smjhh nhi aaya plzz elaborate

if the acceleration is in upward direction then add it to acceleration due to gravity and if acceleration due to gravity is in downward direction then substract it from acceleration due to gravity

thankq

Your weight on the moon would be 1/6 of that on earth. 200lbs on earth = 33lbs on the moon.

The reason ribbon appears red is because it reflects red colour and absorbs the rest. Hence when ribbon is placed in green light, it absorbs all of the green light and not reflecting anything. Hence, ribbon appears black.
