Suppose you wanted to "pull an Einstein," and create a static universe  in which the gravitational attraction of matter is exac

tly balanced by the gravitational repulsion of dark energy with equation-of-state parameter − 1/ 3 < wq < − 1 and energy density εq.
What is the necessary matter density (εm) required to produce a static universe, expressed in terms of εq and wq?


Will the curvature of this static universe be negative or positive?


What will be its radius of curvature, expressed in terms of εq and wq?

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
Naya [18.7K]

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>

A force of 500N Is applied to a steel wire of goss_sectional area 0.2m2 the tensele stress is a. 2.5x10 1nm-2 b. 1 0x102nm-2 c.
Arturiano [62]

Answer:

the tensile stress of the steel wire is 2.5 x 10³ Nm⁻².

Explanation:

Given;

applied force, F = 5000 N

cross sectional area of the steel wire, A = 0.2 m²

The tensile stress of the steel wire, is calculated as;

\sigma = \frac{F}{A} \\\\\sigma = \frac{500}{0.2} \\\\\sigma = 2500 \ N/m^2\\\\\sigma = 2.5 \ \times \ 10^3 \ Nm^{-2}

Therefore, the tensile stress of the steel wire is 2.5 x 10³ Nm⁻².
