Answer:
Modeling Earth’s Tilt
When watching the stars at night, they do appear to move very slowly. This is because the Earth is constantly moving. The Earth completes one “rotation” every twenty-four hours. A rotation is when the planet spins around once. The Earth rotates counterclockwise; this is why the Sun “rises” in the East and “sets” in the West. It is not the Sun’s movement that causes days, but rather the Earth turning around in front of the Sun. The Earth’s axis (the point at which it rotates around, for example, if you were to spin around while standing in one spot, your axis would be an imaginary line running through your head straight down to your feet) is in line with a star named “Polaris”. Polaris is also known as the “North Star” since it is directly above the Earth’s axis. Since this star is directly above the Earth’s axis, it does not appear to move, however, the rest of the stars in the sky move around Polaris (for example: when you spin around, the object directly above your head does not appear to move but everything else seems to spin around that object). Polaris is only seen in the Northern hemisphere and it belongs to the Little Dipper constellation (it’s the last star at the end of the “handle”). Another type of motion is known as “revolution”. Revolution is when one object completes a circular path around another object. The Earth takes 365.24 days to revolve around the Sun. This is why a year is 365 days long. During the year the Earth is angled differently towards the Sun. These changing angles provide us with different Sun intensities and therefore we get four different seasons. Since the Earth is at different positions in space over the year, we see different constellations throughout the year

Factors That Affect Climate Project: Modeling Earth’s Tilt is explained below.
What is rotation?The rotation is the spinning around of an object about its own axis passing through the center.
When the Earth rotates about its own axis, the rotation completes in 24 hours. This causes the day to night and night to day. When the part of Earth is in front of Sun, there is day. But, when the same part of Earth goes away from the Sun, the sunset occurs and then eventually night occurs.
While watching the stars around evening time, they really do seem to move gradually. This is on the grounds that the Earth is continually moving. The Earth finishes one day in each 24 hours. A turn is the point at which the planet twirls around once. The Earth pivots counterclockwise. Not the Sun's development causes days, yet rather the Earth pivoting before the Sun.
The Earth's pivot is in accordance with a star named Polaris. Polaris is otherwise called the North Star since it is straight over the Earth's pivot. Since this star is straight over the Earth's pivot, it doesn't seem to move, nonetheless, the other stars overhead move around Polaris . Polaris is just found in the Northern half of the globe and it has a place with the Little Dipper heavenly body. One more sort of movement is known as "upheaval".
Upheaval is the point at which one item finishes a roundabout way around another item. The Earth requires 365.24 days to rotate around the Sun. To this end, a year is 365 days in length. During the year the Earth is calculated contrastingly towards the Sun. These changing points furnish us with various Sun forces and thusly we get four unique seasons. Since the Earth is at various situations in space over the course of the year, we see various groups of stars consistently.
Thus, the paragraph about how the climate affects the Earth and its tilt is explained above.

A person in a kayak starts paddling, and it accelerates from 0 to 0.509 m/s in a distance of 0.555 m. If the combined mass of the person and the kayak is 63.4 kg, what is the magnitude of the net force acting on the kayak
Answer:
the magnitude of the net force acting on the kayak is 14.77 N.
Explanation:
Given;
initial velocity of the kayak, u = 0
final velocity of the kayak, v = 0.509 m/s
distance traveled by the kayak, d = 0.555 m
combined mass of the person and kayak, m = 63.4 kg
Determine the acceleration of the kayak by using the following kinematic equation;
v² = u² + 2ad
(0.509)² = 0 + (2 x 0.555)a
0.259081 = 1.11a
a = 0.259081 / 1.11
a = 0.233 m/s²
The magnitude of the net force acting on the kayak is calculated by using Newton's second law of motion;
F = ma
F = 63.4 x 0.233
F = 14.77 N
Therefore, the magnitude of the net force acting on the kayak is 14.77 N.

First, evaluate these three models. One represents fission, one fusion, and one radioactive decay. Write three sentences about each one according to the following framework:
---State what reaction the model represents, including what it demonstrates about mass and/or energy.
---State whether you think the model accurately represents the reaction. Explain why or why not.
---Suggest one way to improve the model.
Model A: Two sponge balls representing two atoms are soaked in water. You hold one ball, and your friend holds the other. Then you press the two balls together. As you press them together, water leaks out. What type of reaction does this model represent?
Model B: You draw a tree diagram showing a large atom splitting into two parts and neutrons being released. Your diagram also shows the released neutrons hitting other large atoms, which then each split in two and release more neutrons, which hit more large atoms, and so on. What type of reaction does this model represent?
Model C: You have 100 candies with the letter "M" on one side. You pour the candies into a pan. You count and remove all the candies with the "M" facing upward. Then you shake the pan and again count and remove all the candies with "M" facing upward. You shake, count, and remove candies four more times. What type of reaction does this model represent?
When energy is transferred from system to surrounding then the corresponding reaction known as exothermic reaction in Modle A when we press the ball(atom) the water(energy) is transferred into surrounding hence it is an exothermic reaction.
When a single atom disintegrate to give two or more atom with radioactive substance then the corresponding reaction know as Nuclear Fission reaction. hence Modle B represents Nuclear fission reaction.
The Model C represents Radioactive decay, So in the given example or model the water is playing role of radiation through which we are removing the candies having M on upside.

in 4 seconds, a cheetah can run 112 meters. How fast does this cheetah have to be running? A: 448 m/s || B: 28 m/s || C: 56 m/s || D: 36 m/s
Answer:
B: 28m/s
Explanation:
Use the speed formula
Speed =distance / time
Answer:
[tex]\boxed {\boxed {\sf B. \ 28 \ m/s}}[/tex]
Explanation:
If we want to know how fast the cheetah is running, we need to calculate its speed. This is the rate at which an object moves and the formula is distance divided by time.
[tex]s=\frac{d}{t}[/tex]
The cheetah ran 112 meters in 4 seconds.
d= 112 m t= 4 sSubstitute the values into the formula.
[tex]s=\frac{112 \ m}{ 4\ s}[/tex]
Divide.
[tex]s= 28 \ m/s[/tex]
The cheetah's speed is 28 meters per second and choice B is correct.
For problems 6-9, using the formula net Force = Mass• Acceleration calculate the net force on the object.
Answer:
Find answers below
Explanation:
Mathematically, force is given by the formula;
Force = mass * acceleration
Given the following data;
6. Mass = 8 kg
Acceleration = 2 m/s²
Force = 8 * 2
Force = 16 Newton
7. Mass = 5 kg
Acceleration = 2 m/s²
Force = 5 * 2
Force = 10 Newton
8. Mass = 8 kg
Acceleration = 8 m/s²
Force = 8 * 8
Force = 64 Newton
9. Mass = 200 kg
Acceleration = 3 m/s²
Force = 200 * 3
Force = 600 Newton
A marble block of mass 2 kg lying on ice when given a velocity of 6 m/s is stopped by a friction in 10s then what is the coefficient of friction?
Answer:
[tex]\mu=0.06[/tex]
Explanation:
Given that,
Mass of a block, m = 2 kg
Velocity of the block, v = 6 m/s
It stopped in 10 s
We need to find the coefficient of friction.
The frictional force is balanced by the opposing force such that,
[tex]\mu mg=ma\\\\\mu=\dfrac{a}{g}[/tex]
Where
a is acceleration, a = 6/10 = 0.6 m/s
So,
[tex]\mu=\dfrac{0.6}{10}\\\\\mu=0.06[/tex]
So, the coefficient of friction is equal to 0.06.

Astronomers have measured that there is more helium in the universe than can be explained by the fusion in stars over the last 13 billion years. How do they think the extra helium got into the universe
Answer:
From big bang and stars.
Explanation:
The extra helium got into the universe through big bang and fusion reaction that occur in stars. Our universe formed about 13.7 billion years ago with big explosion, this event is known as big bang. The fusion of hydrogen nuclei in the stars produces helium and energy so we can say that most of the extra helium got into the universe through fusion reaction that occur in the stars continuously.
