Sample questions from this exam

A preview of 3 of the 50 questions. Answers are revealed when you take the exam.

1. Sample 1, Science

   Which of the following is a standard unit of measurement for length in the International System of Units (SI)?
   • A
     Handspan
   • B
     Cubit
   • C
     Meter
   • D
     Inch

2. Sample 2, Logical Reasoning

   While setting up a circuit, Rohan replaces a copper wire with a thick piece of cotton thread. What will happen to the bulb in the circuit?
   • A
     The bulb will glow brighter because thread prevents energy loss.
   • B
     The bulb will fuse immediately.
   • C
     The bulb will not glow because cotton thread is an insulator.
   • D
     The bulb will blink intermittently.

3. Sample 3, Achievers Section

   Three identical metal spheres X, Y, and Z are measured using three different techniques. Sphere X is measured along a straight line using a thread that is later aligned against a scale. Sphere Y is rolled along a curved path and its path length is calculated. Sphere Z is dropped from a height and its displacement is measured. If all paths have the same start and end coordinates, which properties of motion can be inferred?
   • A
     All three spheres must exhibit uniform rectilinear motion simultaneously.
   • B
     The path of Sphere X is purely rotational, while Sphere Y is purely rectilinear.
   • C
     Measuring along a curved path requires a flexible measuring method like a thread rather than a rigid scale directly.
   • D
     The standard SI unit of measurement will change depending on whether the path is straight or curved.
