Explanation:Flexibility and stretching: preventing sports injuries
Many may know about all the different types of sports around the world. Lots can leave serious injuries. All across the world more than 1.2 million people have been injured because of sports or maybe more than that. Most of the injuries have been kids. To prevent these injuries from happening. One thing is stretching if you don’t stretch your bones more than likely you are not into your flexibility and reflexus that for they are very weak. If there is not enough flexibility within your movement you are more than likely not able to stretch. It can help the growth within your bone as well. If you have growth in your bones then you will get less injuries. If you break a bone such as your leg or sprain there is a chance that you will have problems with that specific leg later on in life. To prevent these types of events from happening I say stretch before a sporting game. Stretching can help with the impact of your flexibility. For example, Olympic gymnasts are able to do lots of tricks because their bones have flexibility in their bones. That's not saying that they will not hurt themselves, it's just such a low risk because their bone grew strength and flexibility. Some people's bones can be very sensitive then others so it might be kind of hard for them to be flexible. Another way to help people with their bone flexibility is drinking milk. Milk helps grow your bones. This can help prevent sport injuries in many ways. Lots of people get hurt in football to be more specific because it's such a durable sport as in tough. If they drink a lot of protein and milk before a game maybe even Carbohydrates their bones will be ready for the game. Flexibility and stretching can go lots of ways when it has to do with your body.

A rock is thrown straight upward with an initial velocity of 20 m/s where the downward acceleration due to gravity is -10 m/s^2. How long is the ball in the air before it returns to the thrower's hand?
Answer:
4 seconds
Explanation:
Given:
Δy = 0 m
v₀ = 20 m/s
a = -10 m/s²
Find: t
Δy = v₀ t + ½ at²
0 m = (20 m/s) t + ½ (-10 m/s²) t²
0 = 20t − 5t²
0 = 5t (4 − t)
t = 4

Think and discuss: Why do you think the rate of temperature change does not stay constant over time? If possible, discuss your answer with your teacher and classmates.
Because the temperature of the place its contained in is constantly changing, for example, if you put a room temperature item in the fridge it will become cold, or whatever the temperature you set your fridge to.
Variation in the factors of climate leads to variable temperature around the world.
The rate of temperature change does not stay constant over time because of changes occur in the climatic factors. The climatic factors such as latitude, elevation, nearby water, ocean currents, topography, vegetation, and prevailing winds can't remain constant which leads to variable temperature in different regions of the world.
The temperature will remain the same if all the world has same environmental conditions so we can conclude that variation in the factors of climate leads to variable temperature around the world.

Where does the energy of plasma come from?
Answer:
El plasma es un estado de la materia que se caracteriza por su alta energía e inestabilidad. La energía del plasma, entrando en contacto con la superficie de materiales sólidos – plásticos o metales – modifica sus propiedades fundamentales, como por ejemplo la tensión superficial.
Explanation:
Plasma – el cuarto estado de la materia
A través de aportación de energía se cambia el estado de la materia: de sólido a líquido y de líquido a gaseoso. Si al gas se aporta energía adicional, éste se ioniza, es decir, que por la mayor energía el gas se convierte en plasma - el así llamado “cuarto estado de la materia”.
Answer: I translated it

Plasma is a state of matter that is characterized by high energy and instability. The energy of the plasma, coming into contact with the surface of solid materials - plastics or metals - modifies their fundamental properties, such as surface tension.
Explanation:
Plasma - the fourth state of matter
Through the contribution of energy, the state of matter is changed: from solid to liquid and from liquid to gas. If additional energy is supplied to the gas, it is ionized, that is, due to the increased energy the gas is converted into plasma - the so-called “fourth state of matter”.
Ms. Kasper is in a panic. Her cat, Penny, is stuck in a tree and about to jump out. In order to save her cat, Ms. Kasper needs to run to the tree, 12 meters away. If it takes her cat, 3 seconds to fall, how fast would Ms. Kasper have to run to save her cat?
Answer:
Speed greater than 4 m/s
Explanation:
Given that Ms. Kasper is in a panic. Her cat, Penny, is stuck in a tree and about to jump out. In order to save her cat, Ms. Kasper needs to run to the tree, 12 meters away. If it takes her cat, 3 seconds to fall, how fast would Ms. Kasper have to run to save her cat?
The distance = 12 m
Time = 3s
Speed = distance/time
Speed = 12/3
Speed = 4 m/s
Ms Kasper must run at speed more than 4m/s for her to save the cat.
In what ways are plasmas similar to gases? What makes plasmas different than gases?
Answer:
Like gases, the particles in plasmas are constantly moving at high speeds, and do not have a definite shape or volume. Plasma is formed when the kinetic energy of the molecules in a gas gets very large and the temperature gets very high. This causes electrons to be released by the atom, creating ionized particles, which are positive ions and negative electrons.

The world record for the fastest train on Earth was set by abullet train from Tokyo to Osaka in Japan. Without passengers,it can travel at a speed of 300 km/hr. How many centimeters
per second can it travel?
cm/sec. *round to nearest whole number *
Answer:
8333
Explanation:
300km/hr = 300/60 = 5 km per min
5km/min = 5/60 = .08333333km per sec
km to cm = 100000, so
.083333 * 100000 = 8333
The train would travel at a speed of 8333.33 centimeters/second.
What is speed?The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is a meter/second. The generally considered unit for speed is a meter per second.
As given in the problem the world record for the fastest train on Earth was set by a bullet train from Tokyo to Osaka in Japan. Without passengers, it can travel at a speed of 300 kilometers/hour,
1 kilometer = 1000 meters
1 meter = 100 centimeters
300 kilometers = 300×100000 centimeters
the speed of the fastest train = 300×100000 centimeters /3600 seconds
= 8333.33 centimeters/second
Thus, the speed of the fastest train would be 8333.33 centimeters/second

Which material will heat up the most quickly if placed near a heat source?
Rubber
Plastic
Glass
Metal
Answer:
Metal
Explanation:
Just answered on Apex
Metal is the material will heat up the most quickly if placed near a heat source. Option D is correct.
What is heat ?
The movement of energy from a hot to a cold item is characterized as heat. Heat energy flows from a hot material to a cold one.
This occurs because faster-vibrating molecules transmit their energy to slower-vibrating ones. Heat content is another name for vibrational energy.
It is hot or chilly depending on how much heat is there in the body. The body will be hotter as the heat content increases. The movement of energy from a hot to a cold item is characterized as heat.
The heat flow in the material is due to the free electrons. In the metal, no of free electron is highest. Metal is the material will heat up the most quickly if placed near a heat source.
Hence, option D is correct.

All of the darts hit the center of the board. Some of the darts hit the center of the board. The darts hit the same general area of the board. The darts hit very different areas of the board.
Answer:
The darts hit very different areas of the board.
Explanation:
The bullseye is the point at which darts are most accurate. There is no accuracy nor precision if the darts are neither close to the target nor to one another.
What is dart precision?The degree of similarity between several measurements is known as precision.
Even if the measurements are not exactly the right value, they are very reproducible.
Throwing darts at a dartboard can be used to demonstrate accuracy and precision.
There is precision but not accuracy if every dart lands distant from the bulls-eye but extremely closely spaced apart.
In contrast to a dart that lands far from the bulls-eye, which shows poor accuracy, a dart that hits the bulls-eye is very accurate.
Therefore, The board was struck by the darts in a variety of ways.
