Pleas very fast Determine the resistance of a copper wire that has a cross-sectional area as 9.2 mm2. The length and the electrical resistivity of the copper wire are 78.7 m and 1.67 x 10-6 Ωm. The resistance of a copper wire (in Ω)

1. For tonight's dinner, you have decided to cook a piece of salmon fillet in the oven. Shortly before dinner started, the salmon fillet was removed from the freezer (where it had been kept for a week) and placed into the oven (which was preheated to an air temperature T1), as shown in Figure 1. A timer was then started (t = 0) to keep track of the cooking time. Assume that the thermal capacitance of the salmon fillet is mC J/K and the oven is very large compared 00000000 Salmon fillet at temperature T to the salmon fillet and insulated. Oven at air temperature T1 a) What simplifying assumption can be made pertaining to the effect of the room temperature on the air temperature in the oven? What is the title or general description given to this type of simplifying assumption? Room at temperature TR Figure 1: Salmon fillet in oven

how to calculate this equation to get 18.3 kN get u write for me the step T1/sin(45) = 25 kN/sin(105) T1 = (25 kN/sin(105)) * sin(45) T1 = 18.3 kN
