Option 2 : B or C

Concept:

Motion:

A body is said to be in motion if its position changes continuously with respect to the surroundings with time.
The motion of an object could be uniform or non-uniform depending on whether its velocity is constant or changing.
Uniform and non-uniform motions of objects can be shown through graphs.
The speed of an object is the distance covered per unit of time.

Uniform Motion:

It is a motion in which a material point moves in a straight line at a uniform speed.

Non-uniform Motion:

It is a motion in which the velocity varies with time.

Explanation:

The change in the position of an object with time can be represented on the speed-time graph.
When the speed-time graph is a straight line parallel to the time axis then, the object is at rest and also moves at non-uniform speed.

In a distance-time graph, for uniform speed, a graph of distance traveled against time is a straight line and the motion of the object is uniform.

Consider the following four relational schemas. For each schema, all non-trivial functional dependencies are listed. The underlined attributes are the respective primary keys. Schema I: Field ‘courses’ is a set-valued attribute containing the set of courses a student has registered for. Non-trivial functional dependency: rollno → courses Schema II: Non-trivial functional dependencies: rollno, courseid → email email → rollno Schema III: Non-trivial functional dependencies: rollno, courseid → marks, grade marks → grade Schema IV: Non-trivial functional dependencies: rollno, courseid → credit courseid → credit Which one of the relational schemas above is in 3NF but not in BCNF?
