Assume the values of current in the main branch as well as in the loop.

Write equations of KCL and KVL for the loop and the branch.

Let the current in the 2 ohm resistor bei1+i2

then using KVL equation in closed loop

9−i2−2(i1+i2)=0..............(1)

4i1+2(i1+i2)−3+4i1=16.........(2)

solving we geti1=1.5andi2=2

Thus current through 2 ohm resistor is 3.5 amp

unctions of the Parts of Human Eye Sclera Protects and contains internal parts Cornea Cornea is responsible for maximum refraction of incident light Aqueous Humour Prevents collapse of the eye due to atmospheric pressure changes Iris Iris controls the light entering the eye by adjusting the size of pupil Crystalline Lens Focuses the light reflected by objects on the retina. Ciliary Muscles Alter focal length of the crystalline lens Retina Receives optical image and converts it to electrical impulses Vitreous Humour Maintains the shape of the eye Optic Nerve Carries electrical impulses to the brain. Brain interprets these impulses and produces the sense of vision.

The human eyeis an organ which reacts to light and pressure. As a sense organ, the mammalianeyeallowsvision.Human eyeshelp to provide a three dimensional, moving image, normally coloured in daylight.

Thetheorem of parallel axesstates that the moment of inertia of a rigid body about anyaxisis equal to its moment of inertia about aparallel axisthrough its centre of mass plus the product of the mass of the body and the square of theperpendiculardistance between the twoparallel axes.

Like my answer if you find it useful!

During reaosnanceXl= XCso less current will flow through theseso ir+ ic>1

a. -2/5 b. -10/11 c. -2 d. 2/3

1 is the correct answer

1,2/52,-10/113,-6/34,4/6

2/5 is the first answer

a) is the correct answer

Please give clear photo

3 will be the answer because its distance between 10 and 7

More specificallyCurrent carryingcapacityis defined as the amperage aconductorcan carry before melting either theconductoror the insulation. Heat, caused by an electrical current flowing through aconductor, will determine the amount of current a wire will handle.

One mole is defined as the amount of substance containing as many elementary entities (atoms, molecules, ions, electrons, radicals, etc.) as there are atoms in 12 grams of carbon-12 (6.023 x 1023).Example : Thus, for example, 1 mole of MgBr2is 1 gram-molecule of MgBr2but 3 gram-atoms of MgBr2.

Very cold air can't hold a lot of moisture- it is very difficult to find freezing and humid environments.(The excess moisture that is present actually gets deposited as frost.)Warm air can hold more moisture (think of humid summer days)So when warmer air -holding more moisture- moves into cooler areas, the water molecules turn into snow.

can u plz explain it

Its zero.

Electric field at the equatorial point (vertex A) is parallel to BC.

The component of field perpendicular to BC will be E cos(90) = 0.

Force acts in the direction of electric field. Therefore there is no force perpendicular to BC.

(c) is correct option

resistance is the answer

by ohms law pls like me

The question pertains to Farenheit and Celcius, not Rankine andKelvin scales. There is notemperatureat which degrees F & Ccoincidein the positive. F has smallertemperaturegraduations and is already at 32 when C is at 0, so they can never meet positively. However theydomeet in the negative at -40.

thnx

Vapor pressure is a measurement of the likelihood of the molecules of a puresolventto change from the liquid to the vapor phase.

Compare two solvents, water and alcohol. Of these two solvents, alcohol has a greater tendency to have its molecules at the liquid surface escape into the gas phase. We call this evaporation. As a result, the vapor pressure for alcohol is greater than that of water for a given temperature.

If you add a nonvolatilesoluteto solvent such as water, you decrease the tendency for water molecules to evaporate into the gas phase. In essence, the solute particles obstruct or reduce the likelihood of evaporation.

As a result, fewer molecules change from the liquid to the gas phase, thus reducing the vapor pressure.

An ideal fuel is one that on burning does not emit harmful gasses, gives more heat per weight, should burn optimally i.e. neither too fast nor too slow, and many other features.

Though there is no fuel that meets all characteristics of an ideal fuel still the closest or the nearest answer is Natural Gas

Jet fuel is a clear to straw-colored fuel, based on either an unleaded kerosene (Jet A-1), or a naphtha-kerosene blend (Jet B). Similar to diesel fuel, it can be used in either compression ignition engines or turbine engines.The very high temperatures of jet engines cause gasoline to be a poor fuel because it tends to burn too fast. Kerosene, which is routinely called "Fuel OIL" some places, avoids pre-ignition problems (and some safety hazards) just like higher-octane gas avoids spark-plug knocking.

Ye question Konsa year ka hai ?

It will be option c that is 3as on LHS 2+2=4and RHS =X+1=4x=3

Carrots may be the food best known for helping youreyes. But other foods and theirnutrientsmay be more important for keeping youreyesightkeen as you age.

VitaminsC and E, zinc,lutein, zeaxanthin, and omega-3 fatty acids all play a role ineye health. They can help preventcataracts, clouding of your eye lens. They may also fight the most-likely cause ofvision losswhen you're older: age-relatedmacular degeneration(AMD).

A and C will be the answer

A and C is the correct answer

The technology behind hydro power is fairly simple, but taming the power of water is a major challenge. Hydro power plants are expensive to build, but inexpensive to operate.

both are same because the mass of the earth is same for both attraction and newtons third law as both forces form opposite pair,

Running the refrigerator makes the room warmer and if you leave the door open, the kitchen warms up even faster. The first rush of cold air may cool things down a little, but in the long run, the room will get warmer.To see why, we need to think of heat as energy and cold as a lack of energy. The stove produces heat, but the refrigerator can’t actually produce cold. All the refrigerator does is move heat, or energy, from one place to another. As the food inside the refrigerator loses its heat–or, in other words, gets colder–thatheat ends up in the kitchen.

Head Pump

Physicists call this kind of system a “heat pump.” But like any motor, the heat pump in your refrigerator needs energy just to run. So while it’s busy moving energy out of the fridge and into the kitchen, it’s also drawing in more energy in the form of electricity or gas. Since some of that energy is released as heat, you end up with more heat in the kitchen than you started with.

Batteries have three parts, ananode(-), acathode(+), and theelectrolyte. The cathode and anode (the positive and negative sides at either end of a traditional battery) are hooked up to an electrical circuit.

The chemical reactions in the battery causes a build up of electrons at the anode. This results in an electrical difference between the anode and the cathode. You can think of this difference as an unstable build-up of the electrons. The electrons wants to rearrange themselves to get rid of this difference. But they do this in a certain way. Electrons repel each other and try to go to a place with fewer electrons.

Then, <A = <D(Alternate angles)

75 = x

Therefore, value of x = 75°

(d) is correct option

option a)Ds/dt = ksqrt(s) s^(-1/2) ds = k dt s^(1/2) / (1/2) = kt 2sqrt(s) = kt s = k^2 t^2 / 4 a = d2s / dt2 = k^2 / 2 dW = F dS = ma dS Since the force is constant, W = ma integral(dS) = ma S = (mk^2 / 2) x (k^2 t^2 / 4)

Ds/dt = ksqrt(s) s^(-1/2) ds = k dt s^(1/2) / (1/2) = kt 2sqrt(s) = kt s = k^2 t^2 / 4 a = d2s / dt2 = k^2 / 2 dW = F dS = ma dS Since the force is constant, W = ma integral(dS) = ma S = (mk^2 / 2) x (k^2 t^2 / 4)= 1/8*mk^4t^2 option - A

Whatever mass of 2 balls are and distance between them is anything.

Resistivity is inversely proportional to lengthhence it's ratio will be 3:1Resistance is directly proportional to length hence it's ratio will be 1:3

Resistivity is a measure of the resistance of a given size of a specific material to electrical conduction.

Compared to ultrasound,X-rayshave a much shorter wavelength (higher frequency). This means thatX-rayphotographs produce higher quality images thanultrasoundscans. They show greater detail and clarity. This is vital in terms of detecting small bone fractures or abnormalities.
