What are three ways synthetic polymers affect the environment?

1 answer:

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.

This question can be solved by using Pythagora's Theorem.

The resultant magnitude of the movement is "42.5 units".

The x and y components of the movement are given. We can use Pythagora's Theorem to find the resultant of these movements. Hence, applying the Pythagora's Theorem:

$d = \sqrt{d_x^2+d_y^2}$

where,

d = resultant movement = ?

$d_x$ = movement in x direction = 32 units

$d_y$ = movement in y direction = 28 units

Therefore,

$d = \sqrt{(32\ units)^2+(28\ units)^2}$

d = 42.5 units

A proton and an electron are released from rest, with only the electrostatic force acting. Which of the following statements mus

Anit [1.1K]

Answer:

Their kinetic energy will increase but potential energy will decrease.

Explanation:

Given that

Initial velocities of electron and proton is zero.

We know that ,electron have negative charge and proton have positive charge it means that they will attract to each other.We know that opposite charge attract to each other and same charge repels to each other.

It means that the velocities of proton and electron will increase and that leads to increase in the kinetic energy of proton and electron.

We know that potential energy U

$U\alpha -\dfrac{1}{r}$

So when r will decrease then U will increase but in negative direction it means that U will decrease.

So we can say that their kinetic energy will increase but potential energy will decrease.

The frequency of a wave is 1) A) measured in cycles per second. B) measured in hertz (Hz). C) the number of peaks passing by any

7nadin3 [17]

Answer: E) all of the above

Explanation:

Frequency is the number of vibrations in one second. It is also defined as the number of crests that pass a point in a given time.

The frequency and the wavelength has an inverse relationship.

Frequency is measured in cycles per second or Hertz(Hz).

The relationship between wavelength and frequency of the wave follows the equation:

$\nu=\frac{c}{\lambda}$

where,

$\nu$ = frequency of the wave

c = speed of light

$\lambda$ = wavelength of the wave

Thus all the given statements are true.
