Linear expansivity for aluminum is 23x10^(-6) /K. \n\nIncrease in length is 1.2 x 23x10^(-6) x 50 = 0.0138 m.\n\nTherefore the length is 1.2138 m.

The answers for these questions:\n\nAnswer 1: (c) 27 meters\nAnswer 2: (d) .5 km\n\nAlthough the answer to 2nd question should be 0.4 kms, but I reckon it's just approximate. \n\nYou can email me for further help by clicking Contact Nitro in my answers profile.

a) F = ma\n    F = 0.0412 kg * 9.8m/s^2\n    F = 0.404 N\n\nb) F = 0.0370 kg * 9.8 m/s^2\n    F = 0.363 N\n\nc) The difference in "weight" is equivalent the weight of the displaced volume of water...  So...\n   0.404N - 0.363N = V * 1000 kg/m^3 * 9.8 m/s^2\n   0.041N = V * 9800N/m^3\n   V = 4.18 * 10^-6 m^3   or  4.18 cm^3\n\nd) Oh Juliet you are my density.... (bad joke!)\n     Density = m/V\n     D = 0.0412 kg / 4.18  * 10^-6 m^3\n     D = 9848 kg/m^3

There are more direct conversions, but the most accurate is the "sure" way:\n1 km = 100,000 cm = 10^5 cm\n2.54 cm = 1 in\n12 in = 1 ft\n5280 ft = 1 mi\n\n388 km/h \n= 388(10^5) cm/h\n= 388(10^5)/2.54 in/h\n= 388(10^5)/(2.54)(12) ft/h\n= 388(10^5)/(2.54)(12)(5280) mi/h\n= 241.092 mi/h\n\n^_^

a: width\nb: length\nperimeter = 2 x (a+b)= 420 ---> a+b = 210\nwe need to find max (a x b)\n\na= 210-b ---> area = a x b = b x (210-b) = 210 - b2 = - b2 + 210b = - b2 + 2 x 105 x b - 105squared + 105squared\n= - (b2 - 2 x 105 x b + 105squared) + 105 squared\n= - (b - 105)squared + 11025\n\nSince (b - 105) squared is always >= 0,\n - (b - 105)squared is always <= 0\n  - (b - 105)squared + 11025 is always  <= 11025\n\nthe largest area will be 11025 squared feet. This happens when - (b - 105)squared = 0, which means b = 105.\n\na = 210 - b = 105\n\n\nthe shortest way is to say that a rectangle has the largest area when it's a square, so each side would be 420/4 = 105.

a) E=v/l ---> E = (12/3)*1000=4000 (Volt/meter)\n\nb) v ~ 1/r ---> v2=12*3/5=7.2 Volt\n   E=(7.2/5)*1000=1440 (Volt/meter)\n\nc) w=int(f.dx)=int(Eqdx)=int(vqdx/x)=int(36qdx/x^2)\n\n    = 36q*(-1/5+1/3)=72q/15\n\nq=4*pi*e*l*v/2=2*3.14*8.854*10^(-12)*0.003*12 = 200*10^(-12)\n\n\n---> w=960*10^(-12) J
