We know, AVERAGE speed = Total DISTANCE travelled / Total Time takenWe distance travelled for each journey is dTherefore, Average Speed =                                  We get average speed = km/hr.Mark my ANSWER as brainliest if it helps you in order to appreciate my EFFORTS.

According to the CLASSICAL BCS theory, the key phenomenon occurring in SUPERCONDUCTORS is the pairing of electrons. The SYSTEM of conducting electrons in a superconducting metal forms PAIRS of bound electrons (“COOPER” pairs).

(1) Resistance of each bulb=V/I =50/2 = 25 Ohm(2) Total resistance of two bulbs = 25+25=50 Ohm(3) when they are connected in series with 120 V supply, current will be 120/50 = 2.4 amp.(4)for getting current of 2amps , we need an additional Resistance in series with the CIRCUIT.(5)So, V/ (R+Ra) = 2 amp(6) 120/(50+Ra)= 2 amps or. 100+2Ra=120 or Ra=(120-100)/2=10 OHMS

Since field is CHANGING it's direction, this means both charges have same SIGN. ALSO NOTE that field near q1 is positive, this means q1 should be positive(since field is away from charge if charge is +ve). Also equilibrium position(point where field is ZERO) is near q1, this means q2 > q1.

ee STATES of matter (SOLID, liquid and gas) expand when heated. The atoms themselves do not expand, but the VOLUME they TAKE up does. When a solid is heated, its atoms VIBRATE faster about their fixed points. The relative increase in the size of solids when heated is therefore small......okkk

Two identical metal spheres carry charges of + q and - 2Q respectively. When the spheres are SEPARATED by a large distance r, the FORCE between them is F. Now the spheres are allowed to touch and then MOVED back to the same separation. Find the new force of repulsion between them.

The DIELECTRIC material get polarized when it is placed in an ELECTRIC field. The field produced DUE to the polarization of the material minimize the effect of external field. Hence, the electric field inside a dielectric DECREASES when it is placed in an external electric field.Please mark me brainliest.....Please Give me 5 thanks Please....

Given:u=0v=36km/hrt=20 secondsTo Find:a=? solution:According to NEWTON's FIRST law of MOTION, v=u+at36=0+a×2036=20aa=36/20a=18/10a=1.8m/s²Therefore, ACCELERATION of the car is 1.8 m/s².

जैव विविधता का हमारे जीवन में काफी महत्व है। ऐसा पर्यावरण जो जैव विविधता में समृद्ध है, टिकाऊ आर्थिक गतिविधियों के लिए, विकल्पों के सबसे वृहद अवसर प्रदान करती है। जैव विविधता के हृास से प्रायः परितंत्र की उत्पादकता कम हो जाती है, जिसके कारण विभिन्न वस्तुओं और सेवाओं को प्रदान करने संबंधी उनकी क्षमता भी कम हो जाती है। MARK BRAINLIST ✔✔✔

The main difference between FRACTIONAL and simple distillation is that simple distillation SEPARATES LIQUIDS with a boiling point of at least 50 degrees, while fractional distillation separates liquids with a CLOSER boiling point.Explanation:follow me mark as brainedt

A good example would be heating a tin can of WATER using a Bunsen burner. Initially the flame PRODUCES radiation which heats the tin can. The tin can then transfers heat to the water through conduction. The HOT water then rises to the TOP, in the convection process.

Explanation:The CLUE is in ‘kilowatt hour’. Multiply kilowatts by hours to give you the kWh figure.You have 10 BULBS of 50W so that is a LOAD of 500W, or 0.5kW.10 hours a day for 30 days is 300 hours.0.5 x 300 = 150kWhPlz mark me as a brainliest answer

Explanation: Here P , Q and R in magnitude are equal according to the question, So, we can write, R^2 = P^2 + Q^2 + 2PQcos thetaP^2 = P^2 + P^2 + 2P^2 cos theta      [Acc. to the question]After solving,-1/2 = cos thetacos 120 = cos thetaTherefore, theta = 120Again, the new angle between R1 and Q be ∅ when P is doubled is, We have from Parallelogram LAW, Tan∅ = Tan∅ =  2Q sin 120 / 2Q + Qcos 120After PUTTING theta value we get, Tan∅ = ∞Therefore,∅ =90 degree.

In Star wars Princess LEIA and Han Solo happen to leave the DEATH Star . They areescaping in X wing at a speed of 200m/s. They happen to be spotted by clones wholaunch a missile at them. Leia calculates that the speed of the missile is 300m/s. PrincessLeia calculates that the missile is 3KM away. She asks Han Solo to accelerate to 350m/s. The maximum acceleration of the X wing fighter craft is surprisingly 25m/s2 Find the time taken by X wing to reach the speed of 350m/s. Noe the missile is launched from the samelaunchpad as their Xwing fighter craft, so everything is in straight line.Explanation:please mark as BRAINLIEST answerand follow me plz
