I don't KNOW the ANSWER BEHIND it

Let the side of the CUBE be S, density of water be d, MASS of cube be m, acceleration due to gravity be g.

When the weight is on the block,

Using Archimedes’ Principle ,

Weight of the block + Weight of the mass = Bouyant force (B1)

(Since B1 = volume of water displaced = S3×d×gS3×d×g )

=> m×g+0.2×g=S3×d×gm×g+0.2×g=S3×d×g

=> m=S3×d+0.2m=S3×d+0.2 …. 1

When the mass is removed,

Weight of the block = Bouyant force (B2)

(Since B2 = (S−0.02)S2×d×g(S−0.02)S2×d×g)

=> m×g=(S−0.02)S2×d×gm×g=(S−0.02)S2×d×g

=> m=(S−0.02)S2×dm=(S−0.02)S2×d … 2

From 1 and 2,

S3×d+0.2=(S−0.02)S2×dS3×d+0.2=(S−0.02)S2×d

=>0.2=0.02×S2×d0.2=0.02×S2×d

Taking d = 1000kg/m31000kg/m3

S2=0.01S2=0.01

=> S = 0.1 m = 10cm³

Electric FIELD of the wave ALONG positive X direction can be written as


so, first of all, we have to FIND out k,

given, frequency of wave , f = 150MHz
= 150 × 10^6 Hz = 1.5 × 10^8 Hz
so, angular frequency , = 2π × 150 × 10^6
= π × (300) × 10^6 rad/sec
= 3π × 10^8 rad/sec

K =
c is the speed of light
so, K = 3π × 10^8/3 × 10^8 = π

now, equation of electric field of the wave is
E = 240sin(π x - 3π × 10^8) N/C

It is necessary to study Newtonian mechanics to truly understand Lagrangian mechanics since its underlying foundation is Newtonian mechanics. It is essentially a different formulation of the same thing. In a way when doing Lagrangian mechanics you are still doing Newtonian mechanics just in the way of energy.
Lagrange mechanics provides a much more elegant and direct way of solving the complicated systems especially if you start adding in damping or driving mechanisms. ONE of the attractive aspects of Lagrangian mechanics is that it can solve systems much easier and QUICKER than would be by doing the way of Newtonian mechanics. In Newtonian mechanics for example, one MUST EXPLICITLY account for constraints. However, constraints can be bypassed in Lagrangian mechanics. You can also modify the Lagrange equations pretty easily as well if you want to account for something LIKE a driving or dissipation forces.

An EXAMPLE is gravitational waves, or ripples in space-TIME that COME from interactions between black holes. This was first predicted by Albert EINSTEIN at the turn of the last century, when he showed that time and space are linked; time speeds up or SLOWS down when space is distorted.

As of mid-2017, the Laser Interferometer Gravitational-Wave Observatory (LIGO) Scientific Collaboration has announced three black-hole interactions and mergers detected through gravitational waves, in just two years.

As the chemical reactions occur in the INTERNAL circuit, electrons carry electrical energy through a wire in the external circuit. You can connect the wire to a light BULB or a motor to do WORK. Thus, a galvanic cell CONVERTS chemical energy into electrical energy.

Plane mirror: If you look at the PLAIN mirror the size of the object in the mirror will be the same as that in real.

Concave Mirror: (Folded or bulged inwards) If you see it from far away you can see the IMAGE inverted as compared to real but if you see keeping it near, you will see a magnified (ENLARGED) image of the object in the mirror.

Convex Mirror: (folded or bulged OUTWARDS) It always forms a small and erect image.

Hope this info HELPS you.

They PRODUCE SOUND by MOVING their WINGS up and down...

The phases of the moon are not “formed,” but rather they are the changing appearance of the moon BASED on our VIEW from Earth and the amount of the SURFACE of the moon that is alight from sunlight provided by the sun.

In this way, there REALLY is not any “dark side of the moon”.

P = E/t

60 W = 3000 J / t

t = 3000 J / 60 W

t = 50S

The MOMENTUM also depends UPON MASS.....if mass is less then momentum will also less.....

->It is because they have
*Different PHASE difference
*LIGHT of different wavelength
Due to this they can interfere each other and no corresponding interference pattern COULD be SEEN.

First, you have to choose the right electrodes and electrolyte by figuring out the chemical reaction or reactions you want to happen when the electric current is switched on. The metal atoms that plate your object come from out of the electrolyte, so if you want to copper plate something you need an electrolyte made from a solution of a copper salt, while for gold plating you need a gold-based electrolyte—and so on.

Next, you have to ensure the electrode you want to plate is completely clean. Otherwise, when metal atoms from the electrolyte are deposited ONTO it, they won't form a good bond and they may simply rub off again. Generally, cleaning is done by dipping the electrode into a strong acid or alkaline solution or by (briefly) connecting the electroplating circuit in reverse. If the electrode is really clean, atoms from the plating metal bond to it effectively by joining very strongly onto the outside edges of its crystalline structure.
Now we're ready for the main part of electroplating. We need two electrodes made from different conducting materials, an electrolyte, and an ELECTRICITY supply. Generally, one of the electrodes is made from the metal we're trying to plate and the electrolyte is a solution of a salt of the same metal. So, for example, if we're copper plating some brass, we need a copper electrode, a brass electrode, and a solution of a copper-based compound such as copper sulfate solution. Metals such as gold and silver don't easily dissolve so have to be made into solutions using strong and dangerously unpleasant cyanide-based chemicals. The electrode that will be plated is generally made from a cheaper metal or a nonmetal coated with a conducting material such as graphite. Either way, it has to conduct electricity or no electric current will flow and no plating will occur.

We dip the two electrodes into the solution and connect them up into a circuit so the copper becomes the positive electrode (or anode) and the brass becomes the negative electrode (or cathode). When we switch on the power, the copper sulfate solution splits into ions (atoms with too few or too many electrons). Copper ions (which are positively charged) are attracted to the negatively charged brass electrode and slowly DEPOSIT on it—producing a thin later of copper plate. Meanwhile, sulfate ions (which are negatively charged) arrive at the positively charged copper anode, releasing electrons that move through the battery TOWARD the negative, brass electrode.

It takes time for electroplated atoms to build up on the surface of the negative electrode. How long exactly DEPENDS on the strength of the electric current you use and the concentration of the electrolyte. Increasing either of these increases the speed at which ions and electrons move through the circuit and the speed of the plating process. As long as ions and electrons keep moving, current keeps flowing and the plating process continues.

Hello Mate!

Yes, the CENTRIFUGAL force act along the thread of rotating STONE.

When you start rotating the stones along with thread then the force which attracts stone towards centre is CALLED centrifugal or centripetal force.

Thus the velocity of stone acts in straight direction tangent to circular path and hence stone KEEP on MOVING in circular direction

Have great future ahead!

X-ray CRYSTALLOGRAPHY is a technique used for determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract into many specific directions. By measuring the angles and intensities of these diffracted beams, a crystallographer can produce a three-dimensional picture of the density of electrons within the crystal. From this electron density, the mean positions of the atoms in the crystal can be determined, as well as their chemical BONDS, their crystallographic disorder, and various other information.
In a single-crystal X-ray diffraction measurement, a crystal is mounted on a goniometer. The goniometer is used to position the crystal at selected orientations. The crystal is illuminated with a finely focused monochromatic beam of X-rays, producing a diffraction pattern of regularly spaced spots KNOWN as reflections. The two-dimensional images taken at different orientations are converted into a three-dimensional model of the density of electrons within the crystal using the mathematical method of Fourier transforms, combined with chemical data known for the sample. Poor resolution (fuzziness) or EVEN errors may RESULT if the crystals are too small, or not uniform enough in their internal makeup.
