With the below stated fact I think that the pros of using synthetic materials outweighs the cons.

Before we answer the question

If the pros of using synthetic materials outweigh the cons or otherwise, let us first establish the what a synthetic material is and its pros and cons

Synthetic material

Synthetic material is a material in which a substances are changed chemically to produce a material with different characteristics.

Types of Synthetic material

Plastic bag
Synthetic fiber/cloth
Artificial sweetener
Synthetic fuel
Aspirin

Pros of Synthetic materials

They are used in construction because of there strong bonding
They can be molded
They can be colored into any shade
They are cheap

Cons of Synthetic materials

Sometimes none degradable
They do not absorb water.
They are highly flammable
Melts easily

In conclusion

Although Synthetic materials has so very pressing disadvantages to human kind it is unrefusable the importance of Synthetic materials to the day to day live of all humans

Therefore, I think that the pros of using synthetic materials outweighs the cons

A 730-N man stands in the middle of a frozen pond of radius 5.0 m. He is unable to get to the other side because of a lack of fr

STatiana [176]

Answer:62.11 s

Explanation:

Given

weight of man =730 N

mass of man $m_1=\frac{730}{9.8}=74.48 kg$

radius of pound r=5 m

mass of book $m_2=1.2 kg$

velocity of book $v_2=5 m/s$

let $v_1$ be the velocity of man

conserving momentum

$0=m_1v_1+m_2v_2$

$0=74.48\times v_1+1.2\times 5$

$v_1=\frac{6}{74.48}=0.0805 m/s$

time taken by man to reach south end

$t=\frac{5}{0.0805}=62.11 s$

A 0.413 kg block requires 1.09 N

Virty [35]

Answer:

Explanation:

The equation for this is

f = μ $F_n$ where f is the frictional force the block needs to overcome, μ is the coefficient of static friction, and $F_n = w=mg$ (that means that the normal force is the same as the weight of the block which has an equation of weight = mass times the pull of gravity). Filling in:

1.09 = μ(.413)(9.8) and

μ = $\frac{1.09}{(.413)(9.8)}$ so

μ = .27

An unstretched spring has a length of 10. centimeters. When the spring is stretched by a force of 16 newtons, its length is incr

Fed [463]

Answer:

The spring constant of this spring is 200 N/m.

Explanation:

Given:

Original unstretched length of the spring (x₀) = 10 cm =0.10 m [1 cm =0.01 m]

Stretched length of the spring (x₁) = 18 cm = 0.18 cm

Force acting on the spring (F) = 16 N

Spring constant of the spring (k) = ?

First let us find the change in length of the spring or the elongation caused in the spring due to the applied force.

So, Change in length = Final length - Initial length

$\Delta x = x_1-x_0=0.18-0.10=0.08\ m$

Now, restoring force acting on the spring is directly related to its elongation or compression as:

$F=k\Delta x$

Rewriting in terms of 'k', we get:

$k=\dfrac{F}{\Delta x}$

Now, plug in the given values and solve for 'k'. This gives,

$k=\frac{16\ N}{0.08\ m}\\\\k=200\ N/m$

Therefore, the spring constant of this spring is 200 N/m.

shtirl [24]

Answer:

Answer:

It has sunlight, oxygen, water, and fertile soil.

Explanation:

Sunlight: provides plants (producers) with energy so that the ecosystem is sustainable. Also provides heat and warmth so the planet does not freeze.

Oxygen: obvious. required for human survival and survival of most carbon-based organisms.

Water: required for plant growth and sustainability of carbon-based life.

Fertile soil: a place where plants can grow and produce energy.

I will not write an entire description because your teacher may accuse you of plagiarism and use this topic as proof.

Determine if the data are qualitative, quantitative, or neither. Zinc is a silver-gray metal. Chlorine has a density of 3.2 g/L.

AysviL [449]

Qualitative data gives the information of quality which can not be measured in numbers. For example: Color of eyes, softness of skin.

Quantitative data is information of quantity that can be represented in numbers. For example length and mass of any object.

Zinc is a silver-gray metal is a qualitative data, here silver gray color is quality of zinc metal which can not be measured in numbers.

Chlorine has a density of 3.2 g/L is a quantitative data. The value of density can be compared with other elements by comparing the numbers.

Gallium is not found in nature is neither qualitative nor quantitative.

Nitrogen has a melting point of –210.00 °C is a quantitative data because this is expressed in numbers.

Aluminum is a solid is a qualitative data because it tells about the state of element which can not be measured in numbers.
