Certain metals such as steel,aluminium follow sustainable methods but some does not.
Explanation:
Metal production means conversion of a raw material, such as a metallic ore, to a final form which can be used for some commercial or industrial purpose. In some cases, metal production gives few steps since the metal already occurs in an elemental form in nature.
Sustainable manufacturing is the creation of manufactured products through economic processes that minimize negative environmental impacts while conserving energy and natural resources.
Steel is a uniquely sustainable material because Steel is truly recyclable and is truly recycled.
Aluminum poses no danger of environmental toxicity therefore, secondary aluminum production from recycling scrap has the potential to significantly reduce greenhouse gas emissions.
But some metals production does not follow subsequent methods.
Kevin is a unit used to measure temperature
Answer:
u=78.4m/s
Explanation:
A ball is thrown vertically upward, which is the positive direction.A little later it returns to its point of release.The ball is in the air for a total time of 8.0 s.What is its initial velocity? Neglect air resistance
from newtons equation of motion
s=ut
v=u+at
v=0 because at maximum height reached by the ball the ball stops moving
0=u-9.8*8
u=78.4m/s
u=initial velocity
v=final velocity
a=acceleration due to gravity, 9.81m/s^2
t=time it takes in air
s= distance to get to the maximum before returning
Answer:
False
Explanation:
Some places are more endowed than others.For example, some regions have lots of water (ocean and seas). While others have lots of minerals and forestlands. In addition, other have metallic rocks, wildlife, fossil fuels, and so on. Thus, we can conclude that Natural resources are not evenly distributes across the world.
