Answer:

165.529454

Explanation:

According to the Pythagorean Theorem for calculating the lengths of a right angle triangle's sides, a^2 + b+2 = c^2, where c is the longest side (and the side opposing the right angle). So in your case it would be 150*150 + 70*70 = 27400. And √ 27400 is your answer.

Write a scientific question that is specific and testable. Jack and Jill when up a hill to fetch a pail of water. Once they got

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

The scientific question that can be asked is; What is the depth of the well

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, h, 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 h using the 9 stones

Therefore;

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