Using a diagram or physical model to make a prediction about how lunar phases might be changed if the moon was hit by an asteroid
please help quick
Answer:
mak a plastik moon
Explanation:
make a plastic moon and make a bid dent
The actual effects would depend on various factors, including the size and velocity of the impacting asteroid, the angle of impact, and the specific characteristics of the Moon's surface. Also, these effects might be subtle and might require careful observation to detect changes in lunar phases.
New Crater Formation: The impact of an asteroid on the Moon's surface would create a new crater. This crater would likely disrupt the terrain and create a visible indentation on the Moon's surface.
Altered Reflectivity: Depending on the size and composition of the impacting asteroid, the reflectivity (brightness) of the impacted area could change. A significant impact might expose different layers of the Moon's surface materials, affecting how it reflects sunlight.
Changing Shadows: The new crater and any ejected materials could cast unique shadows during different lunar phases. The angle and position of these shadows might be different from what we typically observe.
Temporary Brightness: Immediately after the impact, the debris and ejected material might temporarily increase the Moon's brightness, potentially affecting its appearance during full moon phases.
Long-Term Effects: Over time, if the impact was significant, the crater and surrounding area might continue to affect the Moon's appearance during different phases, causing irregularities in the brightness and shadow patterns.

You are riding in a car and speed up. What are the possibilities for the acceleration that your car undergoes? (Select all that apply.) Also i'm in 5th grade
-2.0 mph/s
-5.0 mph/s
2.0 mph/s
5.0 mph/s
Answer:
All of them
Explanation:
Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction—or change both. In a car you could accelerate by hitting the gas or the brakes, either of which would cause a change in speed.

Nancy observed that her plant reproduced when she cut off a leaf and planted it. Over time, the leaf grew into…
The offspring plant from the leaf cutting is genetically identical to the parent plant, while a plant that reproduces through pollination will result in genetically diverse offspring due to the combination of genetic material from two parent plants.
The offspring plant that grows from a leaf cutting is a result of a type of asexual reproduction called vegetative propagation. In this process, a portion of the parent plant (such as a leaf, stem, or root) is detached and planted, giving rise to a new plant that is genetically identical to the parent. This means that the offspring plant has the same genetic makeup as the parent plant, making it a clone. The genetic information of the offspring plant is an exact copy of that in the parent plant.
On the other hand, when a plant reproduces through pollination, it involves the transfer of pollen from the male reproductive organ (stamen) of one plant to the female reproductive organ (pistil) of another plant of the same species. This sexual reproduction results in offspring that are genetically diverse. During pollination, the male gametes (sperm) combine with the female gametes (eggs) to form a zygote, which develops into a new plant with a unique combination of genetic traits from both parent plants.
In summary, the key difference between the two types of reproduction lies in the genetic makeup of the offspring. Asexual reproduction, as observed with the leaf cutting, produces genetically identical offspring (clones), while sexual reproduction through pollination generates genetically diverse offspring with unique combinations of genetic traits from both parent plants.

Answer:
The first plant grew from a seed as is, therefore, a "full plant" but the second one is not a "full plant" because it was a part of another so it will probably be weaker than the original.

"The silver trump of freedom had roused my soul to eternal wakefulness. Freedom had now appeared, to disappear no more forever. It was heard in every sound, and seen in every thing....I saw nothing without seeing it, I heard nothing without hearing it, and felt nothing without feeling it."
a. Frederick Douglass believed in freedom, and wanted all slaves to be free.
b. Frederick Douglass had a silver trumpet that inspired the other slaves to be free.
c. Frederick Douglass heard freedom in every word his masters spoke.
d. Frederick Douglass could think of nothing but freedom and how much he wanted it.
Answer:
The answer is B
Explanation:
In the text, Frederick makes it clear to us the silver trump not only inspired the slaves, but him also. He couldn't see the trump without looking at it. He couldn't hear the trump without listening to it, and he couldn't feel the trump without feeling it either. [ i hope this helped :) ]
