ASVAB-TEST Sample Questions & Answers

Osmosis specifically describes the movement of a solvent (in this case, water) across a semipermeable membrane. The movement occurs from an area of lower solute concentration (meaning higher solvent concentration) to an area of higher solute concentration (lower solvent concentration). This process continues until the concentration of solute is equalized on both sides of the membrane. The movement of solute particles is called diffusion.

A misfire requires three main components: spark, fuel, and compression. Since the spark has been verified, the next logical steps are to check the fuel delivery and mechanical compression for that specific cylinder. A clogged or faulty fuel injector would prevent the correct amount of fuel from entering cylinder 1, causing a misfire. Low compression indicates a mechanical problem like a bad valve or worn piston rings, which would also cause a misfire.

Low compression in a specific cylinder is a primary cause of a dedicated misfire code for that cylinder. It means the air-fuel mixture cannot be properly compressed for ignition, pointing to issues like worn piston rings, a faulty head gasket, or problems with the intake or exhaust valves.

This is a critical best practice in shop work. The friction from a grinding wheel generates intense heat. If the cutting edge of a hardened steel tool like a chisel gets too hot (often indicated by a blue or black discoloration), it will lose its temper. This means the metal becomes softer and will no longer hold a sharp edge. Periodically quenching the tool in water dissipates the heat and preserves the hardness and temper of the steel.

This problem is solved using the dilution formula: C1V1 = C2V2, where C is concentration and V is volume. We have: C1 = 70%, V1 = ?, C2 = 10%, V2 = 500 ml. We need to find V1 (the volume of the concentrate). (70%) * V1 = (10%) * 500 ml. 0.70 * V1 = 50. V1 = 50 / 0.70 ≈ 71.43 ml. This is the amount of concentrate needed. The amount of sterile water needed is the total final volume minus the volume of the concentrate: 500 ml - 71.43 ml = 428.57 ml. The closest answer is 71.4 ml of concentrate and 428.6 ml of water.

Let 'h' be the height of the tower and 'x' be the distance from the second measurement point to the base of the tower. We can set up two equations using the tangent function (tan(angle) = opposite/adjacent). Equation 1: tan(60°) = h/x. Equation 2: tan(30°) = h/(x+100). We know tan(60°) = √3 and tan(30°) = 1/√3. From Eq 1, h = x√3. Substitute this into Eq 2: 1/√3 = (x√3) / (x+100). Cross-multiply: x+100 = (x√3)(√3) -> x+100 = 3x. Solve for x: 100 = 2x -> x = 50 feet. Now find the height h using h = x√3. h = 50√3 feet.

This question tests the ability to mentally assemble parts based on instructions and visual cues. The 'key' on Part A is designed to fit into the 'slot' on Part B, which prevents rotation. This is the primary alignment. Part C, the bolt, would then logically be used to secure the assembly, typically by passing through the center of the ring and into the base. This option correctly describes the logical sequence and final state of the assembly.

To 'cavil' is to raise trivial and annoying objections or to find fault unnecessarily. It implies a level of pedantic or frivolous criticism. For example, 'The inspecting officer would always cavil about the precise placement of items in the barracks.'

Bernoulli's Principle states that for a fluid (like air), an increase in speed occurs simultaneously with a decrease in pressure. An airfoil is curved on top and flatter on the bottom. As the rotor blade moves through the air, the air traveling over the curved top surface must move faster than the air traveling along the flatter bottom surface. This difference in speed creates lower pressure above the blade and higher pressure below it. The pressure differential results in an upward force, which is lift.

Pascal's Law states that pressure applied to a confined fluid is transmitted undiminished throughout the fluid. Pressure (P) = Force (F) / Area (A). Therefore, P1 = P2, which means F1/A1 = F2/A2. We are given F1 = 100 lbs, A1 = 2 in², and A2 = 50 in². We need to find F2. Rearranging the formula: F2 = F1 * (A2 / A1). F2 = 100 lbs * (50 in² / 2 in²) = 100 lbs * 25 = 2,500 lbs. The output force is 2,500 lbs.

In a series circuit, current flows through all components. According to Ohm's Law, Voltage (V) = Current (I) * Resistance (R). A voltage drop across a resistor can only be zero if either the current is zero or the resistance is zero. The problem states that the total circuit current is NOT zero. Therefore, the only possible cause for a 0V drop across R2 is that its effective resistance has become zero, meaning it has shorted out. If R1 or R3 had opened, the entire circuit would be broken, and the current would be zero.
