In such cases, the rays coming from a nearby object, after refraction at eye lens, forms an image beyond the retina. This results in hypermetropia.

Option Bis right as Tree can not have a closed loopand in option B it is forming a closed loop

When pressure P (= stress = Force/Area) is applied on the surface of the cube, it is compressed. The compression is due to elasticity. Let Y be the Young's modulus of elasticity of the material of the cube.

When the cube is heated, it expands due to increase in temperature. Let α be the coefficient of thermal expansion of the material. Let L be the side of the cube.

Y = Stress / Strain = P / (ΔL / L) ΔL = compression = P L / Y ΔL = α L T

Hence, α L T = P L / Y

=> T = P / α Y

by 3 vectors we can get zero result.because if we take 2 vectors then then will have equal magnitude to give resultant zeroso we need minimum 3 vector.just use the length and orientation of the sides of anyscalene triangleto form three vectors that sum to zero.

The two factors on which the gravitational force between two objects depends are the masses of the two objects and the distance between their centres

thankyou

It means direction of magnetic lines revearsed inside the magnet

Current flowing in 5ohm resistor is 2A

while in series200+100+50=350 ohmwhile in parallel1/200+1/100+1/50=1/Resultso result=28.5 ohm

if 5 resistance of 0.2 ohm are connected in series then R=R1+R2+R3+R4+R5. THEREFORE 0.2+0.2+0.2+0.2+0.2=1.0ohm answer

let R be the total resistance1/R = 1/3 + 1/6 + 1/41/R = (4+2+3)/121/R = 9/121/R = 3/4R=4/3

in parallel resistance1/Req=1/R1+1/R2+1/R31/R=1/20+1/40+1/601/R=60/800+1/601/R=3600+800/800*60R=800*60/4400=10.9ohm

in parallel resistance1/Req=1/R1+1/R2+1/R31/R=1/20+1/40+1/601/R=60/800+1/601/R=3600+800/800*60R=800*60/4400=10.9ohm

thnx

V= I R = 1 x 5 = 5 volta)1 /Req = 1 / 10 + 1 /151/ req = 5 / 30Req = 6

Now I = 5 / 6

I = 0.8 A

b ) potential difference across A and B

dv= (5 -0 )

dv = 5 volt

potential difference across A and C

dv = { 5 + ( 0.8 x 6 ) - 0 }

dv = 9.8 volt

r total = 5 + 6 = 11Ω

resistance value when connected in parallel=R=R1*R2/R1+R2=R=5*10/5+10=50/15=3.33ohmnow such 8 sets in series=3.33*8=26.66ohm

focal length F = R/2F = 20/2F = 10 cm. ANS..

focal length f=R/2f=20/2f=10cm.Ans...

10 cm is the correct answer of the given

8ohm

4 is ll with 4+44 ll 88*4/8+4=8

Focal length = Radius of Curvature/2 F = R/2 = 20/2 = 10 cm

you should use PV = NRTand consider NRT are constantly so P1 v1 = p2 v2

what is electricity

The answer should be D none of these because both the bubbles will adjust their sizes to become same in size.

Here Ceq is first 2μc are in series to Ceq = 2*2/2+2 = 1now 1 and middle 1 are in parallel.. so Ceq = 1+1 = 2μF again this 2 and lower 2μC are in series , so Ceq = 2*2/(2+2) = 1μC

now at last this 1 and left 1μC are in parallel so, total capacitance is 1+1. = 2μC

now energy stored is = 1/2*(Ceq)*(v²) = (1/2)*(2)*(6)² = 36 units answer.

Energy stored in Capacitor

A charged Capacitor is a store of electrical potential energy.

To find the energy stored in a capacitor, let us consider a capacitor of capacitance C, with a potential difference V between the plates.

There is a charge +q on one plate and –q on the other.

Suppose the capacitor is charged gradually. At any stage ,the charge on the capacitor is q.

L equivalent= 4-9+2*36-5= 1power= 1/2LI^2= 1/2*6= 3

C= Q/V and W = 1/2 ( C×V^2) Therefore if Q becomes 2Q the W will become 2W.

Artificial intelligence (AI) is the simulation of human intelligence processes by machines, especially computer systems. These processes include learning (the acquisition of information and rules for using the information), reasoning (using rules to reach approximate or definite conclusions) and self-correction.

namasteeee

hence option D). is correct

(a)As the graph is made up of only straight lines, The nature of motion is uniform.

(b)The property of a body to resist a change in ots velocity is called inertia. A tendency of an object to resist a change in its state of motion or of rest is called inertia

After completing half revolution, particle speed remains constant so change in speed will be 0 m/sec, but there is change in velocity vector... Both have same magnitude but opposite directions, so magnitude of change in velocity will be 20 m/sec
