5. You have a 12 V battery, a resistor R1 = 120, and another component that requires a current of 2.0 A and a voltage drop of 6.0 V. What value of resistor
would you connect in parallel with Rt, with both resistors in series with the other
component, to produce the required current and voltage drop?
Pls answer

Apsychology student wishes to investigate differences in political opinions between business majors and political science majors at her college. she randomly selects 100 students from the 260 business majors and 100 students from the 180 political science majors. does this sampling plan result in a simple random sample? why or why not? no, because each group of 200 students in the sample does not have the same chance of being selected. yes, because each group of 200 students in the sample has the same chance of being selected. no, because each individual student does not have an equal chance of being selected. yes, because each individual student has the same chance of being selected.
