A. Both Technicians A and B
2. A technician connects one lead of a digital voltmeter to the positive (+) terminal of the battery and the other meter lead to the battery terminal (B) of the starter solenoid and then cranks the engine. During cranking, the voltmeter displays a reading of 878 mV. Technician A says that this reading indicates that the resistance of positive battery cable is too high. Technician B says that this reading indicates that the starter is defective. Which technician is correct?
B. Technician A only
Answer:
Exploration was limited.
Explanation:
The unique geographical disposition of South Africa had a large impact on the movements of Europeans that arrived at the southern tip of the African continent.
Since there were no roads or railroads, the explorers generally relied on waterways to navigate and penetrate deep into the interiors of continents. In South Africa this was impossible because of the intermittent nature of the rivers and great size and flow variation between the dry season and the wet season.
The words award and warp are not very similar. The definitions are completely different. An award is something that you earn, like a monetary compensation or a trophy. You can get an award for being good at something or for example returning a last dog. Warp has a few meanings, but generally means when something is twisted or bent out of shape. It can also mean moving a ship while pulling on rope to something that is connected to shore. They also do not rhyme. However, one way that they are similar are that they both include the letters "war", which has a similar sound in both words.
