Document Summary
Question: (a) what is the difference between weight and mass? (b) can you explain how the following weight-measuring devices work? http://www. overstock. com/guides/how-to-use-a-bathroom-scale http://www. morgandepot. com/servlet/the-306/ac cu-dsh-weigh-galvanized-scoop-hanging/detail http://www. prlog. org/11904338-6874balance-scale. jpg http://www. enasco. com/c/science/m easurement/spring+scales/ In thermodynamics, weight is a force (in newtons, n), not a mass (in kilograms, kg). Pick an answer: 180 kg, 6500 n, 180 n, 6500 kg. My bathroom scale which operates on the spring principle says i. Pick an answer: (a) 110 kg (b) 409. 97 n (c) 41. 8 kg (d)1078. 77 n (e) 289. 24 kg. My bathroom scale says i weigh 110 kg. If i take a balance scale to mars where the gravitational acceleration is. Example: a 1 m3 tank contains a water-steam mixture with vg = If g = 0. 02167 m3/kg and f = 0. 001404 m3/kg, determine the density and specific volume of the mixture. A vertical piston/cylinder has an area of 0. 01 m2 , a volume of. 0. 001 m3, and an internal pressure of 150 kpa.
