<h2>Answers:</h2><h2 /><h2>a) Arrow B</h2><h2>b) Arrow E</h2>
Explanation:
Refraction is a phenomenon in which a wave (the light in this case) bends or changes its direction <u>when passing through a medium with a refractive index different from the other medium.</u> Where the Refractive index is a number that describes how fast light propagates through a medium or material.
According to this, if we observe the rays A an D passing throgh the biconcave lens, we will have two mediums:
1) The air
2)The material of the biconcave lens
This two mediums have different refractive indexes, hence the rays will change the direction.
-For the incident ray A, the corresponding refractive ray is B, because is the ray that bends after passing throgh the lens
-For the incident ray D, the refracted ray is E following the same principle.
Acceleration = Change in velocity / time taken
= (5 - 15) / 2
= -5 ms^-2
I don’t think so because an ice cube melting needs heat and relies on temp while ooblecks transition from solid to quickly depends on force and speed
Answer:
A. refraction of light waves
Explanation:
Refraction happens when light travels from one medium to another and changes speed and bends. This also causes objects to look different sizes and shapes when they are submerged in water.

Cell is the
fundamental unit of life. It is the component of every living organism,
creature and being in the biotic environment. Thus, each of this organisms like
this panda have cells, which is grouped together to form tissues, and when tissues
form together they form the organs and then the organs systems and entirely, as
one organism. An entire organism then is what compose species. This hierarchical
structure is what every organism is totally composed of. But without the cell –these
different types of cells. There would no life.
