You are given the transformer pictured below. what is the voltage across the load resistor if "a" is 7, r2 is 34k ohms, r1 is 15k ohms, and v1 is 87 volts? note that r1 is large so you cannot assume that it has negligible resistance. assume that the transformer is ideal. give your answer in volts to 3 significant digits.

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2
