The main reason why wheelchair ramps are used to move people up a staircase is because it has a high mechanical advantage which leads to a greater efficiency in moving people up the staircase.

  • <em>Let the height of the staircase = h</em>
  • <em>Let the length of the ramp = L</em>

The mechanical advantage of the ramp is calculated as follows;

M.A = \frac{L}{h}

As the length of the ramp increases, people will be move up to a greater distance up the staircase.

Thus, the main reason why wheelchair ramps are used to move people up a staircase is because it has a high mechanical advantage which leads to a greater efficiency in moving people up the staircase.

The scientific method consists of making an observation, ask a question, formulate hypothesis, predict, test, iterate

The scientific question that can be asked is; <u>What is the </u><u>depth of the well</u>

<u />

The reason why the above question is appropriate is as follows:

The items Jack and Jill found at the well

  • No pail
  • A stopwatch
  • Nine equal sized rocks

The information they can get using what they found are;

The time it takes the rock to reach the water surface in the well

The depth of the well

The well's depth, <em>h</em>, is given using the equation of free fall, as follows;

h = \dfrac{1}{2} \cdot g \cdot t^2

Where;

g ≈ Acceleration due to gravity ≈ 9.81 m/s²

By recording the time each rock takes to reach the water surface in the well, the average depth of the well, h_{ave}, can be found by finding the average of the 9 calculated values for <em>h</em> using the 9 stones

Therefore;

The scientific question that is specific and testable is <u>how </u><u>deep </u><u>is the </u><u>well</u><u>, or what is the well's depth</u>

kotykmax [81]
This column actually appears due to the body parts reflecting the light of the sun or moon to the observer.
If the body is not perfectly smooth, only parts of this body would be at the correct position to reflect the light of the sun or moon to the observer.
If the body was perfectly smooth, it would act like a mirror where you can see the full image of the sun or the moon reflected on it.
