Write a short story about a leprechaun.
title: Leprechaun's point of view ;)
I was walking down the old pasture of my beautiful garden when i heard the loudest thud.
"INCOMING HUMAN", I cried out to my family.
We ran inside our tree house and shut the door behind us. Our family was known as the greatest hiders in Green vile. Last week my cousins wen missing, and my brother got squished last year. We totally hate those humans, and I'M SICK OF them!
"When will they ever learn manner, don't they know we live here?!", my wife cried out.
Her face was all red as a tomato i has picked out earlier.
"These are humans for crying out loud, they never learn", I rolled my eyes and sighed.
Write a summary paragraph discussing this experiment and the results. Use the following questions and topics to help guide the content of your paragraph.
Consider the motion of the balloon and its air contents in terms of momentum. In step 1 above, the total momentum of the balloon and its contents was zero. Recall that momentum = mv. Both the balloon and the air inside it had a velocity of zero and therefore the total momentum was zero.
Now think about what happened when the air escaped from the balloon. A certain mass of air accelerated in one direction. In order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. Use this scenario to help you explain why the soda can rotates when the water squirts out of the escape holes.
What was your hypothesis concerning the water-filled can? According to your data, do you think your hypothesis was correct? (Be sure to refer to your data when answering this question.)
Summarize any difficulties or problems you had in performing the experiment that might have affected the results. Describe how you might change the procedure to avoid these problems.
Give at least one more example of Newton's third law in everyday life.

Use this scenario to help explain why the soda can rotates when the water squirts out of the escape holes. Give at least one more example of Newton's third law in everyday life to show how it applies to your life.
Explanation:
The motion of the balloon and its air contents in terms of momentum, balloon's motion, and even the air within. The mass-containing balloon itself would move in a reverse way in order to maintain the system's total momentum at zero, which can be explained by Newton's third law.
What is Newton's Third Law?According to Newton's third law, whenever two bodies come into contact, they exert forces on each other that really were equal in size and directed in the reverse direction.
What is motion?An object changing its location with regard to space as well as time is referred to as being in motion.

Based on the arrows showing direction of plate movement in the diagram below, what type of plate boundary exists between the South American Plate and African Plate?
A
a subduction zone
B
a divergent boundary
C
a transform boundary
D
a convergent boundary
Answer:
a divergent boundary
Explanation:
a divergent boundary is when two plates pull away or separate, as you can clearly see the arrows are going in different directions.
The western margin of the African Plate creates a divergent boundary with the North American Plate to the north and the South American Plate to the south, forming the central and southern Mid-Atlantic Ridge. Therefore, option (B) is correct.
What is a divergent boundary?A diverging boundary, also known as a divergent plate boundary, in plate tectonics is a linear structure that exists between two tectonic plates that are moving apart. Rifts are initially created by divergent boundaries within continents, and they gradually develop into rift valleys.
Along mid-ocean oceanic ridges, the majority of divergent borders are found (although some are on land). The greatest geological feature on Earth, the mid-ocean ridge system is a massive undersea mountain range that spans 23% of the planet's surface and is 65,000 km long and around 1000 km broad.

a) the mass of the car and the height of the inclined plane b) the friction of the surface of the inclined plane and the mass of the car c) the length of the inclined plane and the time for the car to descend the inclined planed) the length of the car and the time for the car to descend the inclined plane
Helpppppppppp!!!!!
Answer:
c) the length of the inclined plane and the time for the car to descend the inclined plane.
Explanation:
The information that is needed to calculate speed is the length of the inclined plane and the time for the car to descend the inclined plane. Thus, the correct option for this question is C.
How speed is defined?Speed is defined as the rate of change of position of an object in any direction. It is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.
If you want to calculate the speed of the car, you must definitely be required to determine the length of the inclined plane through which it is running along with the time for the car to descend the inclined plane. There are some necessary quantities that are required prior to determining the actual values in the same or different contexts.
Therefore, the correct option for this question is C.

8. Find the acceleration of ball A and Ball B
Ball A: F = 10N, Distance Traveled = 10 m, A 10 kg
Ball B: F = 10N, Distance
Traveled = 5 m, B. 20 kg
According to Newton's second law of motion,
acceleration= Net force divided by mass
Net force of A=10N
Mass of A=10kg
F/M
=10N/10kg = 1 m/s2
Acceleration= 1m/s2

Granite has only recently been exposed at a location on Earth’s surface. What will need to happen first in order for granite to become sedimentary rock?
Answers:
1. Weathering and erosion must move pieces of granite to other locations.
2. The granite must be melted and then slowly cooled again.
Answer:
1 weathering and erosion must move pieces of granite to other locations
Explanation:
A thick layer of humus must form on top of the granite. The granite must be broken into smaller pieces by weathering processes. Erosion by wind and water must move pieces of granite to other locations.
