nciple of moments states that when in equilibrium the TOTAL sum of the anti clockwise moment is EQUAL to the total sum of the clockwise moment. When a system is stable or balance it is said to be in equilibrium as all the forces acting on the system cancel each other out. APPLICATIONS of multipole momentsFor these potentials, the expression can be used to approximate the strength of a field produced by a localized DISTRIBUTION of charges (or MASS) by calculating the first few moments.Hope it will help you...

I think UR answer is,Explanation:The concept of ur questions answer is ::White light can be separated into all SEVEN major colors of the complete spectrum or rainbow by USING a diffraction grating or a PRISM. The diffraction grating separates light into colors as the light passes through the many fine slits of the grating. ... A reflection grating is a shiny surface having many fine grooves.please MARK me as brainlist...

Hope it helped youExplanation:FORTUNATELY, Count Amadeo Carlo Avogadro (1776 – 1856) PROVIDED us with Avogadro’s Number, which is the number of molecules contained in 1MOL of a SUBSTANCE at STP.This number is 6.022x10^23.Furthermore, 1mol of a gas at STP occupies 22.4LIn this case, we have 8g of hydrogen at STP, which is 8g/2g/mol = 4molSo, at STP, 4mol of hydrogen occupies 4x22.4 = 89.6LRead more on Brainly.in - brainly.in/question/15667821#readmoreExplanation:

When a PARTICLE moves in a uniform circular motion, its speed as well as the CENTRIPETAL acceleration is constant in magnitude but they CONTINUOUSLY change their DIRECTION. THUS both the velocity and the acceleration changes in uniform circular motion.Explanation:

Let the height of point B be 'h' and INITIAL velocity of particle be 'u'.Total time of LIGHT =t 1 +t 2 So, time to reach at maximum height = 2t 1 +t 2 APPLYING I equation of motion0=u+(−g)[ 2t 1 +t 2 ]⇒u= 2g(t 1 +t 2 )

Scientists have determined that the V-shaped formation that geese USE when MIGRATING serves TWO important purposes: First, it conserves their energy. Each bird flies slightly above the bird in front of him, resulting in a reduction of wind resistanceExplanation:mark as BRAINLIEST PLEASE

1000:1 is the CORRECT ANSWER

i) Its only applicable for point charges at rest. II) Its only applicable in DOSE CASES where inverse square LAW is obeyed.Thanks

1.6 N/metre squarePRESSURE=FORCE/AREA =16/10 =1.6OK Here is your ANSWER. LETS CLEAR.

Energy(E) = VOLTAGE (V) × Current (I) × Time (t)and V = I×R (Resistance)So we get that E = I^2 × R × tPutting values of I, R and t we get =>E = 5^2 × 100 × 2E = 25 × 100 × (2×60×60)So the ans. is 18000000 joules = 18 mega jouleplease mark as BRAINLEST answer

te............ MATERIAL dispersion can be a desirable or undesirable effect in optical applications. The dispersion of light by glass PRISMS is used to construct spectrometers and spectroradiometers. HOLOGRAPHIC gratings are also used, as they allow more accurate DISCRIMINATION of wavelengths.Hope this will HELP you...... #AD

it's your ANSWER EXPLANATION:PLEASE FOLLOW me

here's the answer ....GIVEN that VOLTAGE = 220vcurrent = 0.5 a..RESISTANCE= voltage /currentR= 220/0.5R= 440 is the answer..,HOPE it's helps u.....

The RESISTANCE of the conductor SHOULD  be 20 ΩExplanation : we know that resistance is the RATIO of voltage to CURRENT(From ohms LAW)Resistance = voltage/current=R=V/IVoltage across the conductor = voltmeter reading = 5.8 vCurrent flowing through the conductor = ammeter reading = 290 mA= 290 x 10⁻³= 0.29 ATHERFORE Resistance,R = 5.8/0.29 = 20 ΩHence the resistance of the conductor will be 20 ΩExplanation:

tion:As the train MOVED 40 MIN ago, we can directly sat that. I am going to tell you with the example or may you cheat=Suppose we have the number 3 and 2 and there is a task that 3 moved 5 MINUTES ago of 2 and that we have the audition how late was 2 moved, so for finding that we will see that 3 moved 5minutes ago that means the time distance is 5 minutes, that means 2 moved 5 minutes later. Hope, it was useful because I have not read the question nicely☺️☺️

If the value is high enough, ions, which are drawn towards the conductor, will receive such large ACCELERATIONS that, by COLLISION with air molecules, they will produce vast additional numbers of ions. Therefore the air is made much more CONDUCTING and this FACILITATES a flow of current between the air and the ground.Explanation:

Gas STORAGE is principally used to meet load variations. Gas is injected into storage during periods of low demand and withdrawn from storage during periods of peak demand. It is also used for a VARIETY of secondary PURPOSES, INCLUDING: Balancing the FLOW in pipeline systemsfollow me

The dimension of energy is,Hence 1 joule equals,In the new system of UNITS,Unit of mass Unit of length Unit of TIME Hence unit of energy (MAGNITUDE of Joule) in new system is,We know that 1 calorie equals,Hence magnitude of calorie in new system is,

Now, to solve problems INVOLVING one-dimensional ELASTIC COLLISIONS between TWO objects we can use the equations for conservation of momentum and conservation of internal kinetic energy. FIRST, the equation for conservation of momentum for two objects in a one-dimensional collision is p1 + p2 = p′1 + p′2 (Fnet = 0)orm1v1 + m2v2 = m1v′1 + m2v′2 (Fnet = 0),where the primes (′) indicate values after the collision. By definition, an elastic collision conserves internal kinetic energy, and so the sum of kinetic energies before the collision equals the sum after the collision. Thus,12m1v12+12m2v22=12m1v'12+12m2v'22(two-object elastic collision)expresses the equation for conservation of internal kinetic energy in a one-dimensiona
