Which two facts about plastic affect the environment in a negative way? There are many kinds of plastics to choose from. Some pl
allsm [11]

Some plastics release toxic

They don’t break down over time

Explanation:

The two main facts that shows plastic affects the environment in a negative way is that some of them are toxic and they take a long time to completely break down.

  • Plastics are petrochemical products made up of high molecular mass organic compounds
  • These compounds in plastic polymers takes a very long time to break down
  • They also contain some toxins that are carcinogenic.
  • Foods packed in them can be exposed to these hazardous substances.
  • Most plastics leach chemicals that are very harmful.

What distinguishes mass from weight?
Hunter-Best [27]

Answer:

The answer is A.) Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity on the object.

Explanation:

Your weight would change if you went to the moon because the gravitational pull is different but your mass would stay the same because the amount of matter in you wouldnt change.

A stiff wire 50.0 cm long is bent at a right angle in the middle. One section lies along the z axis and the other is along the l
zloy xaker [14]

Answer:

Magnitude of the force is 2.135N and the direction is 41.8° below negative y-axis

Explanation:

The stiff wire 50.0cm long bent at a right angle in the middle

One section lies along the z axis and the other is along the line y=2x in the xy plane

\frac{y}{x} = 2

tan θ = 2

Therefore,

slope m = tan θ = y / x

\theta=\tan^-^1(2)=63.4^0

Then length of each section is 25.0cm

so, length vector of the wire is

\hat I= (-25.0)\hat k +(25.0) \cos 63.4^0 \hati +(25.0) \sin63.4^0 \hatJ\\\\\hat I = (11.2) \hat i + (22.4) \hat j - (23.0) \hat k

And magnetic field is B = (0.318T)i

Therefore,

\bar F = \hat I (\bar l \times \bar B)

\bar F = (20.0)[(0.112m)i +(0.224m)j-(0.250m)k \times 90.318T)i]

= (20.0)(i(0)+j(-0.250)(0.318T)+k[0-(0.224m)(0.318T)]\\\\=(20.0)(-0.250)(0.318)j-(20.0)(0.224)(0.318T)\\\\=-(1.59N)j-(1.425N)k

Magnitude of the force is

F = \sqrt{(-1.59N)^2+(-1.425N)^2\\} \\F = 2.135N

Direction is

\alpha = \tan^-^1(\frac{-1.425N}{-1.59N} )\\\\= 41.8^0

Magnitude of the force is 2.135N and the direction is 41.8° below negative y-axis

Surgical needles are classified according to their shape; a size of circle shaft within an x,y axis; their point; and their eye.
gogolik [260]

Answer:

Abdominal closure

Explanation:

The needle has a higher taper ratio and a lower tip angle which makes it sharper. The sharpness (taper-point) of this needle is neccesssary for smooth penetration of tissues such as subcutaneous layers and abdominal viscera, so as to minimize the potential damage of fascia.
