  • Q1
    Which of the following statement is TRUE about the concept of Newton’s Second Law of Motion?
    When an object exerts a force on another object, the second object exerts a larger and opposite force to the first object.
    When an object exerts a force on another object, the second object exerts a lesser and same direction of force to the first object.
    When an object exerts a force on another object, the second object exerts an equal and the same direction of force to the first object.
    When an object exerts a force on another object, the second object exerts an equal and opposite force to the first object.

  • Q5
    It is a common observation that naturally occurring processes have a particular direction associated with them. For instance, heat flows from a hot body to a colder body. The property of a system that is used to quantitatively describe this natural direction of events is called
    entropy
    equilibrium
    enthalpy
    energy
