The working principle of the washing machine is centrifugal force. We can separate particles from a solution using centrifugal force according to their size, shape, and density . Centrifugal force can be used to separate the liquid from the suspended particles. Centrifugal force is used to propel the particles to the bottom of the tube. Both of the aforementioned procedures make use of centrifugal force and work similarly Therefore, we may say that the washing machine's operating system is centrifugation. The washing machine turns or spins at a very high speed when we add soap and clothing to combine them, causing the soap and dirt on the clothing to come off the surface. The particles are pushed to the tube's bottom by centrifugal force. During the rinse cycle, the centripetal force principle is applied. By acting from the exterior to the inside of the washing machine this force produces a space that resembles a vacuum in the middle A liquid's chemical or physical activity is enhanced by forced circulation or another periodic motion (like stirring). The clothes bounce back and forth inside the water and detergent -filled drum of the washing machine as it moves , rubbing up against one another to remove stains. 2. What principle is applied in the rinse cycle of a washing machine? Centrifugal force Centripetal force Friction force

Uji Penguasaan Konsep A certain refrigerator has a COP of 5 .00. When the refrigerator is running, its power input is 500 W. A sample of water of mass 500 g and temperature $20.0^{\circ }C$ is placed in the freezer compartment. How long does it take to freeze the water to ice at $0^{\circ }C$ ? Assume all other parts of the refrigerator stay at the same temperature and there is no leakage of energy from the exterior, so the operation of the refrigerator results only in energy being extracted from the water.

Panjang logam A dua kali panjang I logam B dan koefisien ekspansi linier logam B empat kali koefisien linier logam A. Jika pertambahan panjang logam B untuk kenaikar temperatur sebesar $40^{\circ }C$ adalah 10 mm. tentukanlah pertambahan panjang logam A untuk kenaikan temperatur yang I sama! 6,5 cm 6 cm D 4cm 3 cm 5 cm
