10 points Save Ans A sinusoidal voltage (t) has arms value of 220 V. The voltage completes one complete cycle in 20 msec (milliseconds). The magnitude of the voltage at zero time is 200 V. Find the expression for v(t) using the cosine function, v(t) = 311.12 cos(314.167 +50) ov(t) = 220 cos(314.16+ + 50") v(t) - 311.12 cos(314.167 + 24.62") v(t) - 311.12 cos(507 +50°) v(t) = 220 cos(50t + 24.62") v(t) - 311.12 cos(501 + 24.62") Moving to...

els response Question 4 of 5 estion 4 20 points Save Answer Metal carbonates decompose to form metal oxides and carbon dioxide. An experiment was done to determine the composition of a mixture of sodium chloride and sodium carbonate. A sample of the mixture with a mass of 5.05 grams was heated until gas production stopped. After the reaction, the sample had a mass of 4. 17 grams. Assuming that sodium chloride does not react and that the decrease in...
