BUT CAN YOU WRITE THE QUESTION PROPERLY....

Electron beam (EB) welding is a fusion welding process whereby electrons are generated by an electron GUN and accelerated to HIGH speeds using ELECTRICAL fields. This high SPEED stream of electrons is tightly FOCUSED using magnetic fields and applied to the materials to be joined.

tion:Given,Two balls, each of radius R and of equal mass and density, are placed in contact.Step-1:FIND the Distance between the centre of two ballsDistance between the centre of two balls = SUM of their Radii.Distance between the centre of two balls =R+R=2R.Step-2:Express the Mass of a ball as product of Density and Volume.(This would be same for other ball ,given that two balls have equal mass)Since, the shape of the ball is Sphere.Volume of the ball V=34πR3So,Mass of the ball m=ρ×34πR3Step-3:Find the force of gravitation between the two balls.According to Newton's LAW of Universal GravitationF=r2GMmWhere,F= Gravitational Force between two objects.G= Gravitational constantM= Mass of the first objectm= Mass of the SECOND objectr= Distance between objectsHere,.M=m=ρ×34πR3Substituting Values⟹F=(2R)2Gm2⟹F=4R2G(ρ×34πR3)2⟹F=G×ρ2×(34)2×41×R2

T in all STRINGS are20N, 50N, 70N RESPECTIVELY

yesair is the EARTH's ATMOSPHERE. it's a MIXTURE of several gases and elements.it has MASS and weight as it is a MATTER.

hii I think that it helps youExplanation:Newton's SECOND law of motion states that the acceleration of a SYSTEM is directly PROPORTIONAL to and in the same direction as the NET external force acting on the system, and inversely proportional to its mass. In equation form, Newton's second law of motion is a=Fnetm a = F net m .

ial magnets are preferred over NATURAL magnets because natural magnets are WEAK and OFTEN irregular in SHAPE, they can readily be magnetised and demagnetised by turning the current on or off in the coil.

FalseExplanation:RAILWAY tracks expand in summer and contract in WINTER .HOPE it helps :-)

Uses of Bleaching PowderIt is USED for bleaching dirty clothes in the laundry, as a bleaching agent for COTTON and linen in the TEXTILE industry. It is a strong OXIDIZING agent, hence used as an oxidizer in many industries. It is used as a disinfectant which is used for disinfecting water to make potable water.

rmal ENERGY will flow in that DIRECTION until the two objects are at the same temperature. When the two systems in contact are at the same temperature, we say they are in THERMAL EQUILIBRIUM.

is the DEFECT in which a PERSON cannot SEE the DISTANT objects clearly.

ss(M) = 3kgchange in TEMPERATURE(ΔT)= 120K-20K                                      = 100*C                                    c= 490 J Kg-1 K-1                                   Q= McΔT                                  490 × 3 × 100                                  147000 J Ans.Hence 14700 J of HEAT energy needed to raise the temperature of 3 kg of steel from 20K to 120K (or in degree celsius one and the same THING)

Every member of the F1 GENERATION is HETEROZYGOUS and the phenotype of the F1 generation expresses the dominant trait. Crossing two members of the F1 generation produces the second filial (F2) generation. ... This predicted 3:1 phenotypic ratio ASSUMES Mendelian inheritance.

Insulator of electricity5. Increases with its intensityExplanation:match the following.Column A(a) Lubricants(b) Liquid pressure(c) Loudness of sound(d) Ultrasonic sound(e) Pure waterColumn B1. Increases with depth2. Reduce the friction a3. Produced by bats4. Insulator of electricity5. Increases with its INTENSITY

it can be OPENED or CLOSED with the HELP of SWITCH.

The ANSWER is (A) MA this CORRECT answer PLZ me FOLLOW

4m/s^2Explanation:initial velocity = 0m/sfinal velocity = 5m/stime = 1.25sby FIRST equation of motion,v= u+ atlet the ACCELERATION be A5 = 1.25 aa = 5/1.25 = 500/125 = 4A = 4m/s^2

The magnetic field around a STRAIGHT CURRENT carrying CONDUCTOR or wire can be increased by bending the wire into circular loop. ... Each small section of current carrying wire CONTRIBUTES to magnetic field lines. At the CENTRE of circular wire,field lines become straight and perpendicular to the plane of coil.

tion:During World War II, the GERMANS' combined armed forces (Heer, Kriegsmarine and Luftwaffe) committed systematic war CRIMES, including massacres, mass rap e, LOOTING, the exploitation of FORCED labor, the murder of three MILLION Soviet prisoners of war, and participated in the extermination of Jews.

An electrical circuit is simply an energy transformation tool. Energy is PROVIDED to the circuit by an electrochemical cell, BATTERY, generator or other electrical energy source. ... The work done on the CHARGE is equivalent to the electrical potential energy CHANGE of the charge

ravels along a STRAIGHT PATH and also some times along CURVED path its motion is rectilinear motion or simply linear motion. A BUS moves along straight line so we can we one DIMENSIONAL motion's equation to calculate any dimension regarding its motion.

non metals are bad CONDUCTOR EXPLANATION:PLS like

Here the density = 0.8g/cm³And MASS = 64gAs you know density =mass /VOLUMETO find volumeSo, ... is the correct answer please thank my all question and follow

The required final velocity is 4 m/sExplanation:Given :A BODY initially travelling at 10 m/s is given a RETARDATION of 2 m/s² for 3 sTo find :the final velocitySolution :Using the first equation of MOTION, v = u + atwherev denotes the final velocityu denotes the initial velocitya denotes the accelerationt denotes the timeSubstitute, u = 10 m/sa = -2 m/s² (retardation) t = 3 sv = 10 + (-2)(3)v = 10 - 6V = 4 m/sTherefore,the required final velocity is 4 m/s

For the ray starting from point A and travelling in a horizontal direction towards point E, the ANGLE of INCIDENCE is 0 and hence it retraces its path. Similarly, the ray starting from A and travelling towards point C follows the law of reflection. When these rays are produced backwards they appear to meet at a point E and D. Now this image is known as a virtual image. What is the difference between real and virtual IMAGES? In real image, the rays of light actually meet after reflection while in a virtual image it APPEARS to meet but not actually meet. A real image can be obtained on screen but not a virtual image.Explanation:mark me as brainleist

Joints and faults are types of FRACTURES. A JOINT is a fracture along which no movement has taken place, usually caused by tensional FORCES. A FAULT is a fracture or BREAK in the rock along which movement has taken place.

This is an CIRCUIT CONNECTED to the AMMETER or AMPERE

he breaks are TYPICALLY caused by the force of the crash, the BODY being hit with external objects, being thrown forward or backward in an unnatural way, having the limbs and bones twisted or bent UNNATURALLY, being thrown from the CAR or by being CRUSHED in the crash.
