The bouncing back of light waves observed when light waves hit ice and most of them bounce off and radiate back into space is called reflection.
Light waves are a form of waves which produces visible sensitization of the eyes
Light waves have properties of waves such as:
When light waves hit ice, most of them bounce off and radiate back into space.
This property of light waves is known as reflection.

When light waves hit ice, most of them bounce off and radiate back into space, hence, ice is best described as a reflective surface.
A reflective surface is one which can cause incident light to bounce back (reflection).
According to this question, when light waves hit ice, most of them bounce off and radiate back into space. This means that most of the incident lightreflects off the ice surface.
Therefore, the ice surface is best described as a reflective surface.

B.) 75g
C.) 120g
D.) 140g
Answer:
A
Explanation:
Im just guessing its half of 200 as it says
The actual yield of a reaction, where only 50% of a theoretical yield of 200g is formed, is 100g.
The actual yield refers to the amount of product that is actually formed when the reaction is carried out in a real-life setup. In this case, if the theoretical yield (which is the amount of product predicted by stoichiometric calculations) is 200g but only 50% is actually formed, then the actual yield would be 50% of the theoretical yield. Hence, the answer will be 50% of 200g i.e., 100g.

petroleum based is materiel's that contains different kinds of oil and fuel. "which are used in chemical processes to produce plastics".
B. metalloid
C. nonmetal
D. noble gas
67,029 to three significant figures
0.15 to one significant figure
52.8005 to five significant figures
3.17497 to three significant figures
a) 67000 b) 0.20 c) 52.8010 d) 3.17000 are the answers respectively.
Distance is a physical quantity which is measured in meter. If a man travel then it is measured in meters that defines that how much he travel from one point to another point for all these type of things we use to measure distance.
Centimeter is also a physical quantity which is use to measure distance. 1 centimeter is equal to 0.01 meter and 1 centimeter is equal to 0.00001 kilometer.the kilometer is large quantity to measure distance while centimeter is smaller quantity to measure distance.
Kilometer is also a physical quantity which use to measure the distance 1 kilometer is equal to 1000 mtr and 1 kilometer is equal to 100000 centimeter.
For above conclusion, we easily states that the kilometer is large quantity to measure distance while centimeter is smaller quantity to measure distance. Centimeter is also a physical quantity which is use to measure distance. 1 centimeter is equal to 0.01 meter and 1 centimeter is equal to 0.00001 kilometer.
Therefore, a) 67000 b) 0.20 c) 52.8010 d) 3.17000 are the answers respectively.
