<h3>How to define chemical compounds?</h3>

1) The chemical compounds that are present before a reaction occurs is called; reactants

2) The compounds produced from the reaction are called; products

3) Unit of measure, containing Avogadro's number is called; Mole

4) The quantitative proportion of reactants to products is called; Stoichiometry.

5) Two solutions are mixed and an insoluble substance forms; A precipitation reaction

6) An illustration of the reaction that occurs between two or more chemical compounds is called; chemical equation

7) A solid compound that contains water molecules is called hydrates.

A 100-n weight is hung at the middle of a 4-m long horizontal clothesline. If the middle of the clothesline sags by 1 m, what is
Elena L [17]

The tension on each segment of the clothesline is :  110 N

<u>Given data : </u>

mass of object = 100 n  = 10 kg

Horizontal distance of clothesline = 4 m

middle of clothesline sag s by : 1m

<h3 /><h3>Determine the tension on each segment of clothesline</h3>

<u>First step</u> : calculate the horizontal angle made by the sagging

β = arctan ( 1 m / 2m )  ----- ( 1 )

  = arctan ( 0.5 )

  ≈ 26.57°

Note : Tension in th y axis ( Ty ) = Tsinβ

Therefore :

Tension on each segment can be calculated using the formula below

2Tsinβ - mg = 0

solve for T

T = mg / 2sinβ

  = ( 10 * 9.8 ) / 2 * sin 26.57°

  = 98 / 0.89

  = 110 N

Hence we can conclude that the tension on each segment of the clothesline is : 110 N

What detail of the myth is suggested in the poem but not in the painting? What connection between the painting's landscape and t
OverLord2011 [107]

The myth shows the moment when the sun melts the wings of Icarus, while the painting does not present this moment. This detail shows that nature contributes to the death of Icarus.

We can arrive at this answer because:

  • The painting shows only the death of Icarus, showing the moment when he fell into the water and drowned.
  • The purpose of the painting is to show how the universe and all other human beings remained indifferent to Icarus' death.
  • Although the myth also features the death of Icarus, it sets out in more detail.
  • The myth shows why Icarus wanted to use the waxwings and why these wings melted.

The myth focuses on nature's action on the death of Icarus, while the painting reinforces the universe's indifference to this death.

This question is about “Landscape of the Fall of Icarus.”
