The answer is 2Q each.
When the 2 spheres COMES in CONTACT with each other, the charges are DISTRIBUTED equally to both the spheres.

the amount of work is DIRECTLY PROPORTIONAL to the magnitude of DISPLACEMENT

so, if displacement is ZERO, the amount of work will also be zero

-------------------HEY DEAR------------------

HERE IS YOUR ANSWER................

WE KNOW,

(MOMENTUM )^2 = (MV)^2

SO, DIVIDE IT BY MASS

ITS BECOME  :  M(V)^2

          UNITS OF MASS = Kg.

         UNITS OF VELOCITY = m/sec

SO UNITS OF M(V)^2 = kg.m^2 / sec^2......................(1.)

KINETIC ENERGY = 1/2 M (V)^2

            HERE 1/2 IS CONSTANT

SO UNITS OF KINETIC ENERGY = kg.m^2 / sec^2

                                                        = JOULE

COMPARE IT WITH ONE

YOU WILL FIND THAT ITS UNITS ARE SAME

HENCE ,

JOULE IS THE ANSWER...................

=> During sunrise and sunset, the rays have to travel a larger part of the atmosphere because they are very close to the horizon. Therefore, light other than red is mostly scattered away. Most of the red light, which is the least scattered, enters our eyes. Hence, the SUN and the sky appear red.

Side length of CUBE = 0.4 m
so, surface area of cube = side length²
= 0.4 × 0.4 = 0.16 m²

mass of cube = 200 kg
so, weight of cube = Mass of cube × G
= 200kg × 10 m/s² = 2000 N

now, pressure = weight/surface area of cube
= 2000/0.16
= 2000 × 100/16
= 2000 × 25/4
= 500 × 25
= 12500 N/m²

Uniform speed : If the OBJECT cover equal distance in equal interval of TIME.

Non uniform speed : If the speed of a BODY CHANGES w.r.t. time

What is QUESTION U are ASKING

If a circular SHAFT is SUBJECTED to a TORQUE T and a bendingmoment 'M' the RATIO of the maximum SHEAR stress to the maximum bendingstress is given by : A.

hope helps you ❤️❤️

When a ray of light moves from one MEDIUM to another there is a CHANGE in velocity and direction of ray due to refraction which RESULTS in false APPEARANCE of depth of the material. The actual depth that a transparent medium has is known as real depth. Note − Real depth is always greater than apparent depth.

USING conservation of momentum

We get

0=MV+ mv

MV= -mv

8x6 = -4 x v

Thus v= -12m/s

Then KE =mv^2/2

KE = 4* (12)^2 /2

Then KE = 144*2

Thus KE = 288J

HEY,

The FORCE which make the horizontal BEAM turn down to the right, in the direction the CLOCK hands would move, are LABELLED clockwise moment.

The FORCES which would make the beam turn in the opposite direction are labelled anticlockwise moment.

The exam ple is a MAGNET .
in this same poles are repal each other and UNLIKE poles ATTRACT each other.

It can be

1-Speed

This is because the OTHERS are fundamental units WHEREAS speed is a DERIVED unit

2-temperature

This is because the first 3 refer to kinematics whereas temperature is of THERMODYNAMICS

▶️Work is zero if applied FORCE is zero (W=0 if F=0): If a block is MOVING on a smooth horizontal surface (frictionless), no work will be done.

▶️▶️Work done is zero when displacement is zero. This happens when a man pushes a wall. There is no displacement of the wall. Thus, there is no work done.

▶️▶️▶️When a porter carrying some LOAD on his
head moves on a horizontal platform, q = 90°,
therefore the work done by the porter is zero.

▶️▶️▶️▶️ For a body moving in a CIRCULAR path, the
centripetal force and displacement are
PERPENDICULAR to each other. So the work done
by the centripetal force is zero.

▶️▶️▶️▶️▶️man having some load on his head and standing for a while.

Stress strain curve is a behavior of material when it is subjected to load. ... As SHOWN below in the stress strain curve. From the diagram one can see the DIFFERENT mark points on the curve. It is because, when a DUCTILE material like mild steel is subjected to TENSILE test, then it passes various stages before fracture.

Hey MATE here is your answer》》

Plane mirrors are the only type of mirror for which a real OBJECT always produces an IMAGE that is virtual, erect and of the same size as the object. Virtual objects produce real images, however. The focal length of a plane mirror is infinity; its optical power is zero.

Because in plane mirror,the distance of object "a" from the mirror and the distance from image “b” to the mirror are equal.

so by using formula,

1/f=1/a+1/b

We get,

1/f=1/a -1/b (bcz p=q)and (b is TAKEN as negative bcoz image of plane mirror is virtual.

so,

1/f=0,

f=1/0

and any thing divided by zero is infinity.

Hope this answer will help you..《《

Hey dear,

# Answer- l = 2 r1.r2/(r1+r2)

# Explaination-

For an elliptical orbit with ECCENTRICITY e, the position of a particle with perpendicular distance from FOCUS l is represented as,

r=1/(l+ecosθ)

The maximum distance is given by

r1=1/(l−e)

1−e=l/r1 (1)

The minimum distance is given by

r2=1/(l+e)

1+e=l/r2 (2)

ADDING (1)&(2),

2 = l/r1 + l/r2

2 = l [(r1+r2)/r1.r2]

l = 2 r1.r2/(r1+r2)

The distance when perpendicular to PRINCIPAL axis is given by 2 r1.r2/(r1+r2).

Thanks for ASKING.

Plane mirrors are the only type ofmirror for which a real object ALWAYS produces an IMAGE that is virtual, erect and of the same size as the object. Virtual objects produce real images, HOWEVER. Thefocal LENGTH of a plane mirror is INFINITY; its optical power is zero.

ANSWER:

The bubble will appear 3.03 cm below the surface.

Explanation:

GIVEN that,

Refractive INDEX

Refractive index

Radius = -10 cm

The bubble is 4 cm below the surface and is viewed normally from outside.

Using formula of refractive index

Hence, The bubble will appear 3.03 cm below the surface.
