Formula -Velocity = Wavelength × Frequency

Using the above mentioned formula,v = λ × nwhere λ denotes Wavelength and n denotes frequencyGiven,v = 440 m/secn = 220 Hzλ = ?v = λ × n440 = λ × 220=> λ = 440 / 220=> λ = 2WAVELENGTH (λ) = 2 m

A ray of light is deflected twice in a prism. The sum of these deflections is thedeviation angle. When the entrance and exitanglesare equal, thedeviation angleof a ray passing through a prism will be aminimum.

1)As thewhite light, consisits of seven colours in which thevioletcolour has least wavelength andredcolour has the maximum wavelength. Soviolet colouredlightdeviates the most and theredcolouredlightdeviates the least among the sevencomponent coloursof thewhite lightwhenwhite lightis dispersed.

Minimum angel of deviation.The smallest angle through which light is bent by an optical element or system .In a prism ,the angle of deviation is a minimum if the incident and exiting rays form equal angles with the prism faces. The angle is important relative to prism spectroscopes because it can be easily determined .

The value of angle of deviation produced by a prism is different for rays of different colours . It is least for red and maximum for violet .

The value of angel of deviation produced by a prism is different colours. it is least for red and maximum for violet

Thelaw of conservation of angular momentum statesthat theangular momentumof a body that is the product of its moment of inertia about the axis of rotation and itsangularvelocity about the same axis, cannot change unless an external torque acts on the system.

The conservation of linear momentum is based on the principle of Newton’s first law of motion.It implies that for an isolated system, i.e., for a system with no external force, the momentum remains a constant quantity.It also implies the Newton’s third law of motion, i.e., the law of reciprocal actions which states that the force acting between systems is opposite in sign andequalto each other.

Fossil fuels are the non-renewable fuel formed due to burying of plants and animals under sedimentary layers of earth, snow or oil millions of years ago, e.g., coal and petroleum.

If iCis the critical angle for the prism/ material,

Angle of incidence at face AC of the prism = 60°

Hence, refracted ray grazes the surface AC.

=> Angle of emergence = 90°

=> Angle of deviation = 30°.

Given that man's Velocity is 20 m/min.. and river Velocity is 8 m/sec.

the direction should be due north . option A

here is a solution for similar ques.-

answer is a. due north because his reluctant velocity acts towards east and the distance to be covered to reach the other bank increases

Correct answer is (b)

Use v=u+atV=(2i+3j)+10(0.3i+2j)=(2+3)i+(3+2)j=5i+5jhencemagnitude will be √5^2+5^2=5√2 units option c

tha correct answer is option b

in which class you are

The focal length of spectacles is -60 cm and we know that concave lens have the focal length in negative. and concave lens are used to correct myopia or short-sightedness.

the power of the lens =1/f. since the focal length is in centimetres we convert it by dividing by100

100/-60=power of lens

-100/60, i.e, -5/3 or -1.66D

the answer is π/2 m.

Answer: b)0.5

Explanation:

When the wire is bent in the form of the circle the center of mass of the wire shifts to the center of the wire. Thus, the shift in center of mass of the wire is equal to the radius of the circular wire.

Suppose the radius of the circular wire is ‘x’.

The circumference of the wire will be 2πx.

Since, length of the wire is π, so, π = 2πx

=> x = 0.5 m.

This is the shift in origin of the center of mass of the wire.

Sugar is made from sugarcane juice using fermentation process.

option 2

as we know the third kepler’s law of planetry motion that is T²=k R³

so according to that

T²= K *R² => T²/R³ = k .........(1)now new T = 3√3T

{3√3T}²/R'³= k.........(2)

so, equating both

R'³ = R³*(3√3T)²/T²

=> R'³ = 27R³=> R' = 3R

so, R should be increased by (3R-R)*100/R = 200%

Now we know, PV=nRTn = PV/RTn = 2*.410/.082*280n = 10/280

Molar mass = grams /mol= 1/(10/280)= 280/10 = 28 g/mol

Final potential energy = MgH

where H is maximum height of projectile.

H = u^2 sin^2 theta/2g

So, Final potential energyPEf = -Mgu^2 sin^2 theta/2g = - Mu^2 sin^2 theta/2

Depletion region or depletion layer is a region in a P-N junction diode where no mobilecharge carriersare present.

Depletion layer acts like a barrier that opposes the flow of electrons fromn-sideand holes fromp-side.

A depletion region is a natural feature of doping a semiconductor n-type and right to it p-type. At the p-n junction (the border of the two types), te mobile electrons in the n-type. tis is due to the excess electron provided by the n-dopant, diffuse across the junction, into the p-type area

In depletion layer there are electron and proton

This is all well and good, but these newly doped N-type and P-type semiconductor materials do very little on their own as they are electrically neutral. However, if we join (or fuse) these two semiconductor materials together they behave in a very different way merging together and producing what is generally known as a “PN Junction“
