Rani who suffer from nearsightedness has a focal point 50 cm. If you want to read with normal spacing (25 cm), then what is the point nearby?Diketahui : s = 25 cm f = 50 cm Ditanyakan: s =. In experiments on optics, John uses convex lens that focuses 25 cm. In front of the lens is placed objects whose height 3 cm at a distance of 30 cm. high shadow?Ĭompletionf = + 25 cm (cembung) S = 30 cm dan h = 3 cm a. Perbesaran bayangan sebesar :M= 150 = 5x(nyata) 30Ĭ. Tinggi bayangan benda sebesar: M= h=M.h = 5. SUHU DAN KALORKD 4.1 The result of water temperature measurements using the thermometer scale Celsius is 40 C. Determinethe number that is shown if the water temperature was measured with a thermometer Kelvin scale!Īnswer: Diket : C = 40 C 100 40 = 100 K = 273 40 = 313K When the ice is melting, the thermometer scale showed the 20 X X and while it is boiling, thethermometer scale showed the 140 X X.

This situation was measured at 1 atmosphere air pressure. Find The relationship between scale C and scale X Thermometer scale of C, if the thermometer scale showed 80 X X!Īnswer: Diket : Pembagian skala X = (140-20) skala = 120 skala C : X = 100 : 120 = 5 : 6 a. C (80 20) = 5 6 60 5 = 50 6 Jadi, skala C menunjukkan angka 50C If the scale Fahrenheit thermometer showed a temperature of 50 F. Find the scale indicated by theCelsius and Kelvin!Īnswer: Diket : F = 50F 32 = 180 100 = 100 = C = 10Cġ0 + 273 = K K = 283 K A rectangular aluminum plate with the long side - side 50 cm and temperature 30 C. If the coefficientlength of aluminum miaui 25. 10-6 C-1, determine the volume of bullets if heated to 170 C! If the lengthexpansion coefficient of copper 17.ġ0-6 C-1, determine the aluminum square area if the temperature is raised to 150 C!Īnswer: 32 = 180 100 = C = 10 C 32 = 180 = 10 = K 273 10 + 273 = K K = 283 K A bullet-shaped ball made of copper with a radius of 3 mm at a temperature of 20 C. For fixed temperature, if pressure is reduced to4 atmosphere, calculate the volume occupied by gas! (1 atm = 1.013. 105 Pa)Īnswer: Vl = 2 L, P1 = 6 atm, dan P2 = 4 atm P1 v1 = p2 v2 ( 6 atm)( 2 L) = ( 4 atm )V2 62 =3 4 A 4 meter long iron rod with cross-sectional area 25 cm2. The difference in temperature between both Answer:Įnds of the iron 80 C. Determine the amount of heat that crept in the iron per unit of time! Also known coefficient of thermal conductivity of iron 46 Jm-1 C-1.
