Q4, 2kg metal with temperature of 90 "C is put inside a 3 liter water of 30 "C. If the specific heat of the water is three times greater than that of the metal. Find the equilibrium temperature. nie ..... TWDMQ3. A special fluid is in between two co-neint cylinders of radius R:10om, Ry-12cm and length 1 -Im. The inner cylinder is pulled with force F-314% with constant velocity of v-5m/s. Find the viscosity of the fluid 314NQ1. In the circuit to the right, let V1 =8V battery, V2 -4V battery, V3 =7V battery, and let each resistor be a 1$2 resistor. Pick directions for the currents as shown in the diagram. Calculate the currents 11, 12, and 13 in each of the branch of the circuit B 3 V Loop 1 Loop 2 RA V2
