Answer:
Luminol
Explanation:
is a chemical that exhibits chemiluminescence, with a blue glow, when mixed with an appropriate oxidizing agent.
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.

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.
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

tan θ = 2
Therefore,
slope m = tan θ = y / x

Then length of each section is 25.0cm
so, length vector of the wire is

And magnetic field is B = (0.318T)i
Therefore,

![\bar F = (20.0)[(0.112m)i +(0.224m)j-(0.250m)k \times 90.318T)i]](https://tex.z-dn.net/?f=%5Cbar%20F%20%3D%20%2820.0%29%5B%280.112m%29i%20%2B%280.224m%29j-%280.250m%29k%20%5Ctimes%2090.318T%29i%5D)
![= (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](https://tex.z-dn.net/?f=%3D%20%2820.0%29%28i%280%29%2Bj%28-0.250%29%280.318T%29%2Bk%5B0-%280.224m%29%280.318T%29%5D%5C%5C%5C%5C%3D%2820.0%29%28-0.250%29%280.318%29j-%2820.0%29%280.224%29%280.318T%29%5C%5C%5C%5C%3D-%281.59N%29j-%281.425N%29k)
Magnitude of the force is

Direction is

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