How can embroidery machines help the environment? Positive and Negative Impact

svp [43]3 years ago

Answer:

When considering the environmental impact of a sewing machine, it is unlikely that this common household appliance immediately conjures images of ecological threat. However, the sewing machine plays a leading role in the fashion industry, which, according to a report by the Ellen MacArthur Foundation, is one of the largest sources of pollution in the world. The report suggests that the textile and fashion industries produce more pollution than aviation and international shipping combined.

Also, with the production of sewing machinery projected to exceed $7 billion this year in China alone, the distribution of those machines will have a massive impact on greenhouse gas emissions. The mass production and distribution of sewing machines, both industrial and domestic, also requires tons of packaging material which negatively impacts the environment. Lonely Whale and the Point Break Foundation estimate that by 2025 there will be one ton of plastic for every three tons of fish in the ocean. Even more alarming, the United Nations suggests that by 2050 there will be more plastic than fish.

Modern domestic sewing machines are made from plastics and polymers, which increases affordability. It also increases the likelihood that consumers will replace rather than repair, especially in the case of handheld sewing machines, which are a growing novelty. With sewing machines constituting an increasing proportion of the millions of tons of household appliances which end up in landfills, this also poses a significant environmental concern.

In the US, environmental assessments (EAs) must be submitted as part of certain new drug applications (NDAs), abbreviated applications (ANDAs), investigational new drug applications (INDs), and for various other actions, unless the action qualifies for a categorical exclusion (CE) based on an expected environmental concentration of the active moiety below 1 ppb and a claim for no extraordinary circumstances.

How does an atom of chlorine-37 become a chloride ion with a -1 charge?
kirill115 [55]

Answer:

B. The atom gains 1 electron, to make a total of 18 electrons.

Explanation:

Chlorine is the 17th element in the periodic table, so it has atomic number 17:

Z = 17

This means that a neutral atom of chlorine has 17 protons and 17 electrons.

When a chlorine atom gains 1 electron, its electric charge (initially zero) becomes -1, since the electron has negative charge of -1 (in elemntary charge units). This also means that the number of electrons in the ion is now

17 + 1 = 18

So the correct answer is

B. The atom gains 1 electron, to make a total of 18 electrons

lana66690 [7]

Answer:

10 litres.

Explanation:

The air fuel ratio for aircraft is 12:1. It is due to simplicity piper archer is equipped with continuous flow injection system. There is a fuel sensing is Piper Archer which informs the pilot about the low fuel when the fuel level reaches to as low as 10 litres only in the tank. The yellow low furl light will illuminate to alert the pilot.

If it requires 2.0 J of work to stretch a particular spring by 2.0 cm from its equilibrium length, how much more work will be re
valina [46]

Answer:

16 J

Explanation:

It is given that,

Work done, W = 2 J

A spring is stretched by 2.0 cm from its equilibrium length

We need to find how much more work will be required to stretch it an additional 4.0 cm.

Let k is the spring constant of the spring. When W = 2J, and x = 2 cm, then energy required to stretch the spring is :

U=\dfrac{1}{2}kx^2\\\\k=\dfrac{2U}{x^2}\\\\k=\dfrac{2(2)}{(0.02)^2}\\\\k=10000\ N/m

The energy required to stretch the spring from 2 cm to additional 4 cm i.e. 2+4= 6 cm.

W=\dfrac{1}{2}k(x_2^2-x_1^2)\\\\=\dfrac{1}{2}\times 10000\times ((0.06)^2-(0.02)^2)\\\\W=16\ J

So, the required work done is 16 J.

What is the amount of thermal energy that can be stored in an object depends on?
77julia77 [94]
Thermal energy is the total energy of all the molecules in an object. The thermal energy of an object depends on three things: 4 the number of molecules in the object 4 the temperature of the object (average molecular motion) 4 the arrangement of the object's molecules (states of matter).
