Option B is correct.
(B )The incident ray is unpolarized whereas the reflected ray is vertically polarized.
What is a ray?Ray is the next in a series of characters. Ray is made up of two elements: a line and a line segment. It has one terminating end and one indefinitely extending end.
The ray's length cannot be determined. A ray is seen in the diagram below.
Reason ;
Many light sources, such as the sun, create polarised waves ( randomly). Unpolarized light is made up of a large number of waves with all conceivable polarisation directions.
Hence option B is correct.

describe how an earth wire acts as a safety feature
Answer :
The earth wire is a safety device that is attached to the appliance's casing. If the live wire falls loose and hits the casing, the earth wire offers a conduit for the electrical current to pass. The high current flowing through the ground line melts the fuse, turning off the device. If there is no earth wire, we will be the least resistance path for the current to ground in the event of a fault (shock), as there is no other way for the fault current to dissipate. In the event that there is an earth wire. Because the earth line is the least resistance path to the ground, we will be unaffected.

How do stars keep their spherical shape? The force of pressure pushing inward is balanced by the force of gravity pulling outward. Pressure from the rocky surface molds the gas into a spherical shape. The force of gravity pulling inward is balanced by the force of pressure pushing outward. The gravitational force of a star's core pulls its molecules into a ball.
Answer: C
Explanation:
The fusion pressure inside of the stars core creates an outward force acting on the star. This pressure is balanced by the inwards gravitational force that the core of the star is experiencing.

2. Does anything that goes inside the black hole comes out?
Pls write your own answers
Answer:
A black hole cannot eat an entire galaxy.
Some scientists believe that stuff that goes into a black hole might go into another dimension but no one has been able to prove that theory, so most believe that any matter that enters a black hole is torn apart into the smallest components possible and eventually squeezed into a singularity

Intrusive igneous rocks:_____________
A. are fine-grained because they cooled slowly.
B. are never seen by humans, because they form deep in the Earth and are never exposed at the surface.
C. are rocks like basalt, andesite, and rhyolite.
D. cool slowly and are coarse-grained.
Answer:
D
Explanation:
Contrary to answers a, b, and c, volcanic rocks, like basalt, andesite, and rhyolite, are fine-grained which are extrusive igneous rocks.
Intrusive rocks, also called plutonic rock, are coarse-grained and cool slowly without ever reaching the surface. While intrusive igneous rocks do solidify in the earth they do eventually become exposed by erosion.

One step of copper mining requires blasting ore to be able to blasted and extracted from mine.
This process causes harm to the Geosphere (Lithosphere)In this step, they blast the mines inside the earth. Which causes destruction and harm to the geosphere. We know that, land comes under Geosphere also known as Lithosphere.Mercury is used to recover minute pieces of gold that is mixed in soil and sediment. Sometimes Mercury can be lost in this process resulting in widespread contamination of local rivers and lakes.
This causes harm to the Hydrosphere.The portion of earth covered with water is known as hydrosphere.Since, The Mercury is getting mixed with the water. It is polluting the water that is the hydrosphere.Hundreds of tons of rock are unearthed, moved and crushed in mining operation significantly increasing the amount of dust and particulates in the air.
This causes harm to the Atmosphere.The particles of dust get increased in air and eventually gets mixed and spread everywhere.The air is getting polluted which means the atmosphere is getting harmed.Strip mining (also known as mountaintop removal) involves scraping away earth and rocks to get to coal buried near the surface. This often results in the destruction of ecosystems.

Binaural fusion is the process in which the brain processes information from each ear and creates two different perceptions of the location of sound. Please select the best answer from the choices provided T F.
The statement is true. Binaural fusion is the process in which the brain processes information from each ear and creates two different perceptions of the location of the sound.
What is Binaural fusion?Binaural fusion, also known as binaural integration, is a cognitive process in which different auditory information is delivered binaurally, or to each ear separately.
This mechanism is critical in human speech comprehension because one ear may take up more information about speech stimuli than the other.
Yes, the brain processes the information from both ears, but it only uses the tiny difference among them to produce one sense of where a sound is coming from.
Hence the statement is true.
