Document Summary
An apple weighs 60 g and has a volume of 75 cm3 in a refrigerator at 8oc. List three intensive and two extensive properties of the apple. 0. 000 075 kg m3 = 800 kg m3. T = 8 c; kg m3 ; v = Extensive m = 60 g = 0. 06 kg. V = 75 cm3 = 0. 075 l = 0. 000 075 m3. The standard acceleration (at sea level and 45 latitude) due to gravity is. Solution: ma = 0 = f = f - mg. F = mg = 2 kg 9. 80665 m/s2 = 19. 613 n. When you move up from the surface of the earth the gravitation is reduced as g = 9. 807 3. 32 10-6 z, with z as the elevation in meters. Solution: go= 9. 807 ms-2 gh = 9. 807 3. 32 10-6 11 000 = 9. 7705 ms-2. Wo = m go ; wh = m gh.
