Which statement is true about the law of reflection?
The angle of reflected light is the same as the incoming angle of light.
The angle of reflected light distorts the image to appear larger or smaller.
The angle of reflected light is smaller than the incoming angle of light.
The angle of reflected light is larger than the incoming angle of light

Answers

Answer:

The law of reflection defines that upon reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray, with respect to the normal to the surface that is to a line perpendicular to the surface at the point of contact.

The reflected ray is always in the plane defined by the incident ray and the normal to the surface at the point of contact of the incident ray.

The images produced by plane mirrors and curved mirrors can be understood by the law of reflection.

Law of reflection is defined as:

The principle when the light rays falls on the smooth surface, the angle of reflection is equal to the angle of incidence, also the incident ray, the reflected ray, and the normal to the surface all lie in the same plane.

What is Reflection of Light?

The process through which light rays fall on the surface and gets bounced back is known as a reflection of light.

Explanation:

Answer: The angle of reflected light is the same as the incoming angle of light.

Explanation:

The law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane. The angle of reflection is equal to the angle of incidence.

Which letter in Figure 1 represents meiosis? Why?
Which letter in Figure 1 represents mitosis? Why?​

Answers

The letter D in Figure 1 represents meiosis, while letter A represents mitosis. Meiosis is a reductional cell division.

Mitosis is a type of cell division where a parent cell divides to produce two genetically identical daughter cells (in this case, diploid cells).

Meiosis is a reductional cell division where a parent cell divides twice to produce four daughter cells having half of the genetic material.

Meiosis occurs in germinal cells, while mitosis occurs in somatic (body) cells.

how long does it take for a photon to travel through the convection zone

Answers

Answer:

50 million years

Explanation:

It can take a photon as long as 50 million years to travel all the way through the radiative zone. The convection zone surrounds the radiative zone. In the convection zone, hot material from near the Sun's center rises, cools at the surface, and then plunges back downward to receive more heat from the radiative zone.

Hoped that helped:P

Answer:

D, or hornfels.

Hornfels is a metamorphic rock formed by the contact between mudstone / shale, or other clay-rich rock, and a hot igneous body, and represents a heat-altered equivalent of the original rock. This process is termed contact metamorphism. It's not like animal metamorphism.

Do you think there should be regulations on industries that make fertilizers and farmers who use fertilizers to ensure that excess nitrogen does not reach water ecosystems? Why or Why not? Write at least five sentences defending your answer.

Answers

Given what we know, we can confirm that there should in fact be regulations on fertilizer manufacturers and farmers who use fertilizers to ensure that excess nitrogen does not reach water ecosystems due to its negative effects on the ecosystems.

What is Nitrogen?Nitrogen is an element that is most often found in a gaseous state.It is color and odorless.It is found in the air, water, and almost everywhere else around us, but in low quantities. It can form toxic gases such as ammonia when in high concentrations in the air.

Why can it be harmful in excess?Excess nitrogen in water is very bad due to the effect on algae. Contrary to what we may initially believe, excess nitrogen can help algae to grow at very high rates.However, these algae blooms sap the oxygen from the water at increased rates and damage if not kill all other marine life in the area as a consequence.

Therefore, regulations should be in place for fertilizer manufacturers and farmers who use fertilizers to ensure that excess nitrogen does not reach water ecosystems due to its negative effects on the ecosystems.
