Aluminum foil is often incorrectly termed tin foil. If the density of tin is 7.28g/cm³,what is the thickness of a piece of tin f
leonid [27]

Answer:

15.0 µm

Step-by-step explanation:

Density = mass/volume

        D = m/V     Multiply each side by V

      DV = m        Divide each side by D

        V = m/D

Data:

m = 1.091 g

D = 7.28 g/cm³

 l = 10.0 cm

w = 10.0 cm

Calculation:

<em>(a) Volume of foil </em>

V = 1.091 g  × (1 cm³/7.28 g)

  = 0.1499 cm³

(b) <em>Thickness of foil </em>

The foil is a rectangular solid.

V  = lwh                            Divide each side by lw

h = V/(lw)

   = 0.1499/(10 × 10)

   = 1.50 × 10⁻³ cm           Convert to millimetres

   = 0.015 mm                  Convert to micrometres

   = 15.0 µm

The foil is 15.0 µm thick.

<h2>Question no 1:</h2><h2>Answer:</h2>

The correct answer is option A which is Sarah is correct because genetic diversity occurs over a long period of time.

<h3>Explanation:</h3>
  • Genetic diversity is a large number of allelic combinations for a trait in specie in a population.
  • Genetic diversity is caused due to mutations or random breeding in a specie.
  • It is good for the adaptation of specie in an environment, due to diverse in genotypes and phenotype of a trait.
<h2>Question number 2:</h2><h2>Answer:</h2>

The correct answer is option B which is the species will adapt to the changes.

<h3>Explanation:</h3>
  • Adaptation to an environment means changing your body in such a way to reduce the harmful affects of changing the environment on the body.
  • For example, the long and thick fur of sheeps in a snowy area will protect them from cold.
  • If the environment changes, the first thing a specie do is an adaptation to that change in the environment.
<h2>Question 3.</h2><h2>Answer:</h2>

The correct answer is option D which is, "The spines of a cactus protect it from animals".

<h3>Explanation:</h3>
  • Adaptation to an environment means changing your body in such a way to reduce the harmful affects of changing the environment on the body.
  • For example, the long and thick fur of sheeps in a snowy area will protect them from cold.
  • So the plant of cactus was in danger due to animals. So the start growing spines in response to animals.
  • Hence the correct answer is option D.
<h2>Question 4.</h2><h2>Answer:</h2>

The correct answer is option B which is, "Marie's plant will lean toward the sun so that it can get the most sunlight".

<h3>Explanation:</h3>
  • The plant will lean towards the sun light by the mechanism of phototropism.
  • Phototropism is the mechanism of growth of the plant in a specific direction in the response of light.
  • There are two types of phototropism.
  • One is a positive phototropism in which plant grows towards the light.
  • The other is negative phototropism in which plant grows away from the light.
  • In this question,the plant will do positive tropism.
<h2>Question no. 5</h2><h2>Answer:</h2>

The correct answer is option B which is, "The dodo bird could not adapt quickly to the challenges of the environment".

<h3>Explanation:</h3>
  • Adaptation to an environment means changing your body in such a way to reduce the harmful affects of changing the environment on the body.
  • For example, the long and thick fur of sheeps in a snowy area will protect them from cold.
  • So the dodo could not adopt to the environment. For the positive adaption of survival, they should be afraid of sailors but the would not afraid of a sailor.
