Questions and Answers
  • 1. 

    What is the equation for density?

    • A.

      Mass*volume

    • B.

      Mass/volume

    • C.

      Volume/mass

    • D.

      None of the above

    Correct Answer
    B. Mass/volume
    Explanation
    The equation for density is mass divided by volume. This equation is used to calculate the amount of mass per unit volume of a substance. By dividing the mass of an object by its volume, we can determine how compact or concentrated the object is. Therefore, the correct answer is "mass/volume".

    What is atmospheric pressure?

    • A.

      Pressure exerted by oxygen?

    • B.

      Pressure exerted by chemical gases?

    • C.

      Pressure exerted by the gases that make up the earth's atmosphere?

    • D.

      None of the above

    Correct Answer
    C. Pressure exerted by the gases that make up the earth's atmosphere?
    Explanation
    Atmospheric pressure refers to the force exerted by the gases present in the Earth's atmosphere on a surface. It is caused by the weight of the air molecules above the surface and is responsible for various weather phenomena. Therefore, the correct answer is "pressure exerted by the gases that make up the earth's atmosphere."

    What is a Pascal unit of pressure?

    • A.

      Newton per meter squared

    • B.

      Newton per meter cubed

    • C.

      Newton per meter

    • D.

      None of the above

    Correct Answer
    A. Newton per meter squared
    Explanation
    A Pascal is a unit of pressure, defined as one Newton per square meter. It is named after the French mathematician and physicist Blaise Pascal. This unit is commonly used in scientific and engineering applications to measure pressure, such as in fluid dynamics and atmospheric pressure. Therefore, the correct answer is Newton per meter squared.

    What is a hydraulic system?

    • A.

      A system that decreases force by applying to a large surface area

    • B.

      A system that decreases force by applying to a small surface area

    • C.

      A system that multiplies force by applying to a large surface area

    • D.

      A system that multiplies force by applying to a small surface area

    Correct Answer
    D. A system that multiplies force by applying to a small surface area
    Explanation
    A hydraulic system is a system that multiplies force by applying it to a small surface area. This is achieved through the use of fluid pressure, where a small force applied to a small piston can generate a larger force on a larger piston. This principle is commonly used in various applications such as hydraulic lifts, brakes, and heavy machinery. By utilizing the multiplication of force, hydraulic systems allow for the efficient transmission of power and movement.

    What does Pascal's principle state?

    • A.

      When force is applied to a confined fluid it is applied equally throughout

    • B.

      When force is applied to a confined fluid it is applied differently throughout

    • C.

      When force is applied to fluid it is not applied at all

    • D.

      None of the above

    Correct Answer
    A. When force is applied to a confined fluid it is applied equally throughout
    Explanation
    Pascal's principle states that when force is applied to a confined fluid, it is applied equally throughout. This means that the pressure exerted by the fluid is transmitted undiminished in all directions. This principle forms the basis for hydraulic systems, where a small force applied to a small piston can generate a larger force on a larger piston, allowing for the amplification of force.

    What does Bernoulli's principle state?

    • A.

      A moving fluid exerts more pressure than the surrounding fluid

    • B.

      A moving fluid exerts less pressure than the surrounding fluid

    • C.

      A moving fluid exerts less force than the surrounding fluid

    • D.

      A moving fluid exerts more force than the surrounding fluid

    Correct Answer
    B. A moving fluid exerts less pressure than the surrounding fluid
    Explanation
    Bernoulli's principle states that a moving fluid exerts less pressure than the surrounding fluid. This principle is based on the idea that as the speed of a fluid increases, its pressure decreases. This can be observed in various phenomena, such as the lift generated by an airplane wing or the flow of blood in the circulatory system. The principle is derived from the conservation of energy and is widely used in fields like fluid dynamics and aerodynamics.

    What is fluid? 

    • A.

      A substance that can not flow easily

    • B.

      A substance that can flow easily

    • C.

      A solid

    • D.

      None of the above

    Correct Answer
    B. A substance that can flow easily
    Explanation
    The correct answer is "a substance that can flow easily." Fluid is defined as a substance that can flow and take the shape of its container. Unlike solids, fluids do not have a fixed shape and can easily move and flow. This includes liquids and gases, which are both considered fluids.

    What does Archimedes' principle state?

    • A.

      The buoyant force on an object is = to the weight of the fluid displaced by the object.

    • B.

      The buoyant force on an object is more than the weight of the fluid displaced by the object.

    • C.

      The buoyant force on an object is less than the weight of the fluid displaced by the object.

    • D.

      None of the above

    Correct Answer
    A. The buoyant force on an object is = to the weight of the fluid displaced by the object.
    Explanation
    Archimedes' principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object. This means that when an object is submerged in a fluid, it experiences an upward force equal to the weight of the fluid it displaces. This principle explains why objects float or sink in fluids and is used to calculate the buoyant force acting on an object.

    What is the buoyant force?

    • A.

      An upward force

    • B.

      A downward force

    • C.

      A horizontal force

    • D.

      Diagonal force

    Correct Answer
    A. An upward force
    Explanation
    The buoyant force is the upward force exerted on an object submerged in a fluid, such as water or air. This force is a result of the pressure difference between the top and bottom of the object. The greater the volume of the object submerged, the greater the buoyant force. This force is responsible for objects floating in water or air, as it counteracts the force of gravity pulling the object downward. Therefore, the correct answer is "an upward force."

    What is pressure?

    • A.

      Volume pushing on a surface

    • B.

      Force pushing on a surface

    • C.

      Mass pushing on a surface

    • D.

      None of the above

    Correct Answer
    B. Force pushing on a surface
    Explanation
    Pressure is defined as the force applied per unit area on a surface. It is the result of a force exerted perpendicular to the surface, causing the molecules of the surface to be compressed or pushed. Therefore, the correct answer is "force pushing on a surface."
