What are three ways synthetic polymers affect the environment?

Physics
1 answer:
gulaghasi [49]3 years ago
6 0
There are two types of polymers which are natural and synthetic polymers. Natural polymers do not affect the environment but synthetic polymers do. This type of polymers are produced by humans. These release reactants which are considered hazardous to humans and the environment. Synthetic polymers include rubbers, plastics, and adhesives, and these are considered non-biodegradable and non environmental friendly. As these build up in the environment, in causes problems such as chemical poisoning to all the living things around it. Hope this helps.

What are the difference between conductor and insulator? ​
Anvisha [2.4K]

Answer:

  • A conductor allows energy e.g. electric charge or heat to pass through it easily. While an insulator does not let electric current or heat to travel through it.
  • Insulators have strong molecular bonds. While molecular bonds are very weak in conductors.
  • Insulators have very low conductivity. While in conductors, it is very high.
  • Insulators have a very high resistance and therefore the electrons are held together very firmly. The conductors, on the other hand, have a very low resistance.
  • Insulators do not have any electric field, neither inside nor on the surface. While in conductors, it is found on the surface and continues to be zero in the inner part of the conductor.

zhannawk [14.2K]

Answer: B. development of female sex

Development of female sex characteristic is not associated with the amount of cortisol in the body.

Explanation:

Cortisol is a steroid hormone secreted by the adrenal gland. It facilitates stress response, regulates blood sugar level and helps fight infections. High cortisol level leads to Cushing syndrome and low cortisol level leads to Addison disease.

Obesity is a  symptom of Cushing syndrome while weight loss is a symptom of Addison disease. Thus levels of cortisol can affect body weight as well.  When in a stressful situation, our body pumps excess cortisol.

Cortisol level in our body is generally high in the mornings and low in the midnight.

How many excess electrons must be present on each sphere if the magnitude of the force of repulsion between them is 3.33××10âˆ
AlekseyPX

Answer:

There are 756.25 electrons present on each sphere.

Explanation:

Given that,

The force of repression between electrons, F=3.33\times 10^{-21}\ N

Let the distance between charges, d = 0.2 m

The electric force of repulsion between the electrons is given by :

F=k\dfrac{q^2}{r^2}

q=\sqrt{\dfrac{Fr^2}{k}}

q=\sqrt{\dfrac{3.33\times 10^{-21}\times (0.2)^2}{9\times 10^9}}

q=1.21\times 10^{-16}\ C

Let n are the number of excess electrons present on each sphere. It can be calculated using quantization of charges. It is given by :

q = ne

n=\dfrac{q}{e}

n=\dfrac{1.21\times 10^{-16}}{1.6\times 10^{-19}}

n = 756.25 electrons

So, there are 756.25 electrons present on each sphere. Hence, this is the required solution.
