    Answer:

    This question is incomplete but the completed question is below

    The height of an individual step on a staircase is

    closest to

    (1) 2.0 × 10⁻² m (3) 2.0 × 10⁰ m

    (2) 2.0 × 10⁻¹ m (4) 2.0 × 10¹ m

    The correct option is 2

    Explanation:

    This question seeks to test our knowledge of physical setting. Let’s examine the options one after the other (if possible, you can get a 30-centimeter meter rule close-by because the question is/can be practical)

    (1) 2.0 x 10⁻² m: This is same as 0.02 m or 2 cm; it’s obvious this can’t be the height of a step.

    (2) 2.0 x 10⁻¹ m: This is same as 0.2 m or 20 cm. Using the meter rule you have, this should make sense but let’s consider other options.

    (3) 2.0 x 10⁰ m: Anything raise to power of zero is 1. Hence, this is 2m or 200 cm. This is obviously not the case also.

    (4) 2.0 x 10¹ m: This is even larger than (3) above hence, it’s less likely also.

    From the above, the most closest answer is (2)
