The place where the manure pile was stored last year, a narrow strip that used to be a limestone gravel farm road, and the spot where fertilizer is usually transferred from a nurse truck to the tractor spreader are all examples of parts of a 25 hectare field that should be treated as follows when sampling soil for the soil test lab
A) carefully avoided while sampling
B) more intensively sampled (more cores per hectare) than other areas
C) sampled more deeply than other areas
D) included, like all other areas, in the sample sent in for analysis
E) sampled and sent in separately

A simple method of solving circuits consisting of only two resistors in parallel (with either equal or unequal values) is called the “____________________ over the sum” method.
Fill in the blank(s) with the appropriate word(s).
A voltmeter is used to determine the voltage across a resistive element in the circuit of Figure P2.77. The instrument is modeled by an ideal voltmeter in parallel with a 120-k? resistor, as shown. The meter is placed to measure the voltage across R4. Assume R1 = 8 k?, R2 = 22 k?, R3 = 50 k?, RS = 125 k?, and iS = 120 mA. Find the voltage across R4 with and without the voltmeter in the circuit for the following values:
Assumptions:
The voltmeter behavior is modeled as that of an ideal voltmeter in parallel with a 120- k? resistor.
