No Explanation:Electric FIELD linesnever forms a close loop.It EXIST as rays LIKE FASHION for point charges .It is never that a electric field is circular due to a single charge.

reater than CV because when GAS is heated at constant volume,WHOLE of the heat SUPPLIED is USED to increase the temperature only. But when gas is heated at constant pressure,the heat supplied is used to increase both temperature and volume of gas.

please please MAKE me brainlist ok I'm urs don't be saf dearANSWERPower of lens is defined as the reciprocal of the focal length of the lens EXPRESSED in meter.SI UNIT of power is Dioptre denoted by D.Focal length of FIRST lens f 1 =40 cm=0.4 mSince the focal length is positive, so it is a convex lens.Power of lens P 1 = f 1 1 = 0.41 =2.5 DFocal length of SECOND lens f 2 =−20 cm=−0.2 mSince the focal length is negative, so it is a concave lens.Power of lens P 2 = f 2 1 = −0.21 =−5 D

re Four FUNDAMENTAL Forces of Nature...GRAVITATIONAL force, Weak Nuclear force, Electromagnetic force and Strong Nuclear force...gravitational force!!...The gravitational force is a force that attracts any two objects with mass. We call the gravitational force attractive because it always tries to pull masses together, it never pushes them APART. In fact, every object, including you, is pulling on every other object in the entire universe...electromagnetic force!!...The fundamental force associated with ELECTRIC and magnetic fields. The electromagnetic force is carried by the photon and is responsible for atomic structure, chemical reactions, the attractive and repulsive forces associated with electrical charge and magnetism, and all other electromagnetic phenomena...hope!!...it helps UHH...❣️

tion:Asking for the direction of the FIELD at a particular POINT is the same as asking for the direction of the force EXPERIENCED by a positive test charge placed at that point. A test charge is a charge with a magnitude so small that placing it at a point has a negligible affect on the field around the point.We take positive charge as a test charge because positive charge is higher potential and negative charge is lower potential. Therefore, influence of positive charge on other charges is greater than negative charges. We can also take negative charge but the EFFECT will be lower.please mark it as brainliest

no only TEMPERATURE AFFECTS and MATERIAL USED

hey MATE your answer is here ........a force ,arising from the body's inertia, which appear to act on a body moving in a circular path and is directed away from the CENTRE around which the body is moving........ HOPE it will help you....... please mark the answer as BRAINLIST...... don't forget to follow me for such type of answers.......OK....... THANKS......

1 current is INDUCED Needle of galvanometer deflects 2 more current is induced if no of TURNS are increased

the object moving in CIRCULAR motion and is DIRECTED towards the centre under the force of GRAVITY ALONE is KNOWN as.......

t very GOOD at PHYSICS SORRY but I cannot ANSWER itCheck it on GOOGLE Or some where elseSorry Once again

al of Moments:-_________________________________SUM OF THE ANTICLOCKWISE MOMENTS=SUM OF THE CLOCKWISE MOMENTS____________________________________Explanation:- When several force acting on a pivoted body,the TENDS to rotate it about an axis passing through the pivot.The result moment of all the force on the pivoted point can be found taking the algebraic sum of the movement of each force about the point.Question arises how to find the algebraic sum?we have to take The anti-clockwise moment is taken as positive.The clockwise movement is taken as negative._________________________________________If the algebraic sum of moments of all the forces,acting on the body ,about the axis of rotation is zero , the body is in equilibrium._______________________________________Verification of the principal of movements(there is a picture follow it for verification)Suspended a metre rule horizontally from the FIXED support of strong thread at point O.Now we will suspend 2 springs BALANCES A and B on either side of scale.Now suspend some slotted weights W1 and W2 on the spring balances .Now adjust either the slotted weight on the spring balances or the position of spring balance on either side of the thread.Let Distance OB=l2Let weight A = w1Let weight B=w2Observation:-The weight w1 tends to turn the meter rule clockwise, while the weight w2 tends to turn the rule anti-clockwise._____________________________________CLOCKWISE MOMENTO=W1 * L1ANTI-CLOCKWISE MOMENTO=w2 * L2_____________________________________W1 L1 = W2 L2I.e., clockwise moment= anti-clockwise moment

22.4lExplanation:

Explanation:FACTORS That Affect RESISTANCE How much resistance a material has depends on several factors: the type of material, its width, its length, and its temperature. All MATERIALS have some resistance, but certain materials resist the flow of electric CURRENT more or LESS than other materials do.There are 4 different factors which affect resistance: The type of material of which the resistor is made. The length of the resistor. The thickness of the resistor. The temperature of the conductor.

is is coalbecause DIAMOND graphite and FULLERENE are different types of CARBON

u=40cmReal,INVERTED,same SIZE as the object.Explanation:

Respiration is considered as exothermic REACTION because energy is released in this process. GLUCOSE COMBINES with oxygen PRESENT in our cells to form carbon DIOXIDE and water along with energy.

it is a DEVICE to MEASURE the FLOW of ELECTRIC CURRENT in a curcuit.

our BODY temperature is 98• C. when it GOES up than we feel LIKE sick

Vg. =. MG /. Mb. ×. Vb i THINK that HELPS U thanks mark it's BRAINLIEST and please follow me

force = ma = m * V - u / t = 70g * 0 - 0.5 / 0.5 = 70 Nhope it HELPS

I think it is WRONG you mean to SAY MAGNETIC lines of FORCE?

are right black light when is passed never GIVES 7 coloursonly because it is a mixture of MANY colours and colours cannot be separated as the colours are COMPLETELY mixedwhere as in a WHITE light the colours are not much combined and as we know white light it is more than black light as we GET white light from the Sun and it is an abundant resource it is easy to use white light rather than using black light

tion:we CONSIDERED good sources of energy those who the materials are those things which save the nature and use the minimum product and we can do a LOT to go through this week and considered for a good sources of energy such as electricity use of natural gases LIKE CNG LPG gases for the gases that to home use in homes using of electric CARS and use of the solar energy are example of good sources of energy in which we can save the earth and also the natural PRODUCTS thank you

Magnetic axis is defined as the IMAGINARY LINE NS which passes through the magnetic north and SOUTH poles of any bar magnet. Length of magnet is defined as the distance between one of the magnetic poles and the centre of the magnet.......Explanation:

tion:Here,we can think from non inertial frame of reference that as the lift is moving upward with an acceleration of g10,so net force acting downward for the two blocks will be their weight+(g/10)their mass.So,if the TENSION in the string is T,we can write for the larger BLOCK as, 3g+3g10−T=3a (as it is going down)similarly for the smaller block T−1.5g−1.5g10=1.5a (where, a is the acceleration of the blocks relative to the lift)Solving both we GET, T=(115)gNow,the SPRING is attached to the pulley which is bearing the tension of the string from both the side,so the spring will show a reading of 2T=(225)g=43.12Nso,reading of the spring BALANCE will be 22g5g=4.4KgRead more on Brainly.in - brainly.in/question/10522668#readmore
