The extension of an elastic spring is found to vary directly with the weightsuspended from it. If a weight of 75 kg produces an extension of 1.4 cm,calculate the weight that would produce an extension of 9.8 cm. |

Answer» hence w=525kg, l=9.8 cm hggdsdfdddddddddddfgffghhhjjjjkllkhhfx 9,18,27,36 is the common number between 7 to 37 which is divisible by 9. 9,18,27,36 is the common number between 7 to 37 which is divisible by 9. option b is the right answer hence w = 525;kg , l=9.8cm hence w = 525 kg,l= 9.8cm hence w = 525 kg ,l= 9.8cm hence w = 525 kg l= 9.8cm 1.4cm=75kg1cm=75/1.4=75x10/14=750/14therefore9.8cm=(750/14)x9.8=525kg 1 kg = 1000g75kg = 75000gExtension = 14/10In second caseWeight = xExtension = 98/10 Cross multiplication 75000*98/10=14/10*x Multiplying both sides with 10 7350000 = 14x14x = 7350000x = 7350000/14x = 525000 In gram, x = 525000 gmIn kilograms, x = 525 kg Solution:- Given, the extension of an elastic spring found to vary directly with the weight suspended from it so write => l = kw (1) where k = proprotionally constant l = represent the extension of an elastic spring w =represent the weight w = 75kg l= 1.4 cm so substitute these vale In equation (1) we have 1.4 = k× 75 k =1.4/ 75 so equation (1) becomes l =1.4/75 × w when l = 9.8 cm = 1.4 / 75 × w => w = 9.8 × 75 / 1.4 = 525 kg Additive inverse of ²/-9 b is the best answer 10% x of+20% of y=24;3x-y=20 the answer is 525 kg multiply 1 hence w =525 kg , l=9.8 cm The answer will bew=525 kilograms ,l=9.8cm the correct answer is 80kg hence w=525kg , l = 9.8is the correct answer 525 kg is correct answer the extension of an elastic spring found to vary directly with the weight suspend from it w=525kg I=9.8 525 is the best answer 525kg... because let x should be weight for9.8cm .then75kg/1.4cm=xkg/9.8cmthen x= 525kg 9182736 is the common no. between 7 to 37 which is divisible by 9. 75 kg = 1.4 cm 53.5714286 =1cmthere fore9.8 cm = 9.8 x 53.5714286therefore answer is 525 w= 525 kg l = 9.8 cm is the best answer 525 is the correct answer hence, W=525 kg, l=9.8cm the correct answer is w=525kg , l=9.8cmlike my answer answer is this guestion w is 525kg and I is 9.8 I don't know please like Qno 4 ,A=49130 CI=8270 The answer w=525 kg., l=9.8 cmPlz like my answer w = 525kgI = 9.8cm. w=52kg. l=9.8cm is the correct answer w=525 and l=9.8 is the correct answer of this question if 75kg produces an extension of 1.4cm then, 525kg will produce an extension of 9.8cmtherefore, 525kg is my answer w=525 and l= 9.8 is the correct answer of this question 75 is the right answer is right answer 75 is the right answer for this question we = 525 kg , l = 9.8 cm kg cm 75 1.4x 9.8 cross multiplication9.8/1.4=8therefore answer is=75×8=600 75×9.8=525kgtherefore answer is 525kg gigiyuyyuhugugguggihihlho |
