The field of a new soccer stadium is watered by three individual sprinkler systems, as shown by the A, B, and C regions in the figure below. Each sprinkler system is controlled by exactly one of three on-off valves in an underground maintenance room, and each sprinkler system can be turned on without turning on the other two systems. Each of the valves is presently in the off position, and the field is dry. The valves have not been labeled, so you do not know which valve controls which sprinkler system. You want to correctly label the valves as A, B, and C. you also want to do it by making only one trip up to the field. You cannot see the field from the maintenance room, and no one is available to help you. What procedure can you use to determine how to correctly label the valves? Assume that all of the valves and all of the C sprinkler systems are operating properly. Also assume that the sprinklers are completely off or completely on. Explain your reasoning. either

In the last column in the data table, it says that it's about voltage(v) divided by current(A) is equal to ohms so V/A = ohms. So if it's V/A and if you divide them to get the slope it's (y2-y1)/(x2-x1) then shouldn't V be the y value and A be the x value? And can you also try to use a line of best bit instead of drawing the line through each dot?
Draw a circuit diagram for the case where both resistors (1000 ohms and 100 ohms) and an LED are connected in series and parallel. Taking the internal resistance of a single LED as 20 Ω, calculate the total current in the series and parallel circuits drawn. Then calculate the power, P (P = IV ), going through the LED in each of these cases. The battery is 3V.

The voltage V in a simple electrical circuit is slowly decreasing as the battery wears out. The resistance R is slowly increasing as the resistor heats up. Use Ohm's Law, V = IR, to find how the current I is changing at the moment when R = 356 Ω, I = 0.02 A, dV/dt = −0.01 V/s, and dR/dt = 0.06 Ω/s. (Round your answer to six decimal places.)
In the circuit shown in figure 1, epsilon is equal to 41.0 V, R1= 4 ohms, R2= 6 ohms, and R3= 3 ohms. (A) what is the potential difference Vab between points a and b when the switch S is open? (B) for the 4 ohm resistor, calculate the current through the resistor with S open. (C) for the 6 ohm resistor, calculate the current through the resistor with S open.

A solar panel of length L and width W produces 28.4 kWh in a day. Under the same conditions (i.e. the same amount of solar energy available and the same efficiency) a solar panel of length 2L and width 2W would produce how many kWh in a day? Round off your answer to 2 decimal places, but do not write the unit.
