    • Bernoulli's principle

    • Newton's first law of motion

    • Newton's second law of motion

    • Newton's third law of motion

    Correct Answer
    A. Newton's second law of motion
    Explanation
    This statement is Newton's second law of motion. It states that an unbalanced force acting on a body will cause the body to accelerate in the direction of the force. The magnitude of the acceleration is directly proportional to the force applied and inversely proportional to the mass of the body. This law is commonly expressed as F = ma, where F is the force, m is the mass, and a is the acceleration.

    Which type of oil system stores the oil in a tank fitted to the side the engine

    • Wet sump

    • Dry sump

    • Hot tank

    • Cold tank

    Correct Answer
    A. Dry sump
    Explanation
    A dry sump oil system is a type of oil system that stores the oil in a separate tank, typically mounted to the side of the engine. This system is commonly used in high-performance and racing engines as it offers several advantages over a wet sump system. By storing the oil externally, it allows for a larger oil capacity, better oil control, and reduced oil foaming. It also prevents oil starvation during high-speed cornering or acceleration, ensuring proper lubrication of engine components. Therefore, the correct answer is dry sump.
