A logistics specialist is planning a convoy route between two bases 270 miles apart. The lead vehicle maintains a constant speed of 45 mph. A scout vehicle departs from the same base, travels to the destination, and immediately returns, meeting the convoy along the route. If the scout vehicle's average speed is 60 mph, how many miles from the initial departure base will the convoy be when the scout vehicle meets it?
A combat engineering team needs to create a temporary triangular landing zone. The lengths of the sides of the zone are 150 meters, 200 meters, and 250 meters. To ensure stability, they must place a support beacon at the geometric center (centroid) of the landing zone. What type of triangle is this, and which principle would be used to locate the centroid?
The word most opposite in meaning to 'TACITURN' is:
An avionics technician is troubleshooting a control system with multiple logic gates. The system output is unexpectedly 'LOW' (0). The technician isolates the final gate, which is an AND gate. The simplified schematic is shown below: ``` Input A ---|\ | AND --- Output Z Input B ---|/ ``` To troubleshoot this, the technician measures the voltage levels at inputs A and B. Which of the following sets of measurements would be considered an anomaly that requires further investigation upstream?
A heavy-duty recovery vehicle uses a compound pulley system to lift a disabled engine block. The system consists of 6 supporting rope segments. A diagram of a similar, but simpler, system is shown below. ``` |-------[Fixed Axel]-------| | | | / \ / \ / \ [P1] [P2] [P3] | | | |-----------|-----------|---[Load] ``` Ignoring friction, if the engine block weighs 1,800 lbs, what is the minimum force the winch must apply to the rope to lift the block?
During a field sanitation course, a recruit learns about osmosis as it relates to water purification. Osmosis is the net movement of which substance across a semipermeable membrane?
A vehicle exhibits a 'P0301' diagnostic trouble code, indicating a misfire in cylinder 1. A mechanic has already verified that the spark plug and ignition coil for cylinder 1 are functioning correctly. Which of the following are the MOST likely remaining causes for the misfire? (Select TWO)
True or False: When sharpening a chisel on a bench grinder, the tool should be periodically dipped in water to prevent the steel from overheating and losing its temper.
A field medic needs to dilute a 70% concentrated antiseptic solution to create 500 ml of a 10% solution for wound irrigation. How much of the original 70% concentrate and how much sterile water should be mixed?
A surveyor is using trigonometry to determine the height of a radio tower. From a point on the ground, the angle of elevation to the top of the tower is 30 degrees. The surveyor then moves 100 feet closer to the tower, and the angle of elevation becomes 60 degrees. What is the height of the tower?
