Answer: Hello There!...............
You decrease the kinetic energy by either stopping the object and let it rest (which would give it potential energy) or changeing the slope.
Explanation:
Mark me brainest please. Hope this helps. Anna ♥
Depending on the sort of energy involved, you can use a variety of techniques to reduce the quantity of energy an object contains. To slow motion in mechanical systems, you can add friction or resistance, which turns kinetic energy into heat.
When dealing with thermal energy, you can place the object in a cooler environment, which will enable it to transmit heat and cool down. It is possible to lessen an object's potential energy by changing its height or location within a gravitational field. Reactions that release energy can dissipate chemical energy. These strategies essentially entail aiding energy transfer or conversion to a less energetic state, hence lowering the object's overall energy content.

T he relationships between the systems of units of temperarua can be completed in the table
K = ºC +273
ºF = 9/5 ºC + 32
Systems of units are systems that arbitrarily define which are the fundamental units of measurement. The most widely used system worldwide is the International Measurement (SI) where the basic units are: Length, mass, time, absolute temperature, current, amount of substance and light intensity, all other units are derived from these.
But there are still in the world several practical systems that are used, among them the temperature measurement is one of the measurements that has more practical systems, for example the centrifugal and fahrenheit degrees are extremely used.
The relations to pass between systems of units of temperature we have;
K = ºC +273
ºF = 9/5 ºC + 32
With these expressions we can make the changes of units
1) T = 0ºC
K = 0 + 273
K = 273 K
ºF = 9/5 0 + 32
ºF = 32º F
2) T = 212ºF
ºC = 5/9 (ºF-32)
ºC = 5/9 (212 - 32)
ºC = 100ºC
K = 100 + 273
K = 373
3) T = 450 K
ºC = K - 273
ºC = 450-273
ºC = 177ºC
ºF = 9/5 177 +32
ºF = 350.6ºF
4) T = 98.6ºF
ºC = 5/9 (98.6 - 32)
ºC = 37ºC
K = 37 +273
K = 310K
5) T = -273ºC
K = -273 +273
K = 0
ºF = 9/5 (-273) + 32
ºF = 523.4ºF
6) T = 294K
ºC = 294 -273
ºC = 21ºC
ºF = 9/5 21 + 32
ºF = 69.8ºF
7) T = 77ºF
ºC = 5/9 (77 -32)
ºC = 25ºC
K = 25 + 273
8) T = 225K
K = 298K
° C = 225 - 273
ºC = -48ºC
ºF = 9/5 (-48) + 32
ºF = -54.4ºF
With the equivalences between sysems of units, units can be converted from one system to another.
Be careful since some of the equation is of physics, the temperature must be in absolute units or in degrees kelvin.
In conclusion, with the relationships between the systems of temperature units, the table can be completed

Answer:
Acceleration
Explanation:
Let me teach u a trick, most teachers loves to tell students to memorize what the slope means, and what does the area below the graph mean, and i think this is bs
So how u do it is this
Now it is a velocity vs time
Now to find the slope u would take
Velocity / time
Now what is the unit for velocity? m/s
What is the unit for time? s
Therefore since u know to find the slope u use
Velocity divide by time
So just take the unit of velocity divide the unit of time and see what unit u get
m/s ÷s
m/s x 1/s
= m/s^2
What unit is this?
This is the unit for acceleration
This trick works for every graph u see, and let me show u an extra bonus one
Now u are velocity vs time graph
Now if they ask u what does the area below graph means?
So u know area is just height x length, in other words y axis × x axis
So it means velocity x time
Therefore what would u get? Same trick
m/s x s
= m
What is m? m is meter, and this stands for displacement

Conversion of mass from grams into kg :

They turn around and walk 15-m to the left in 8.0-s. What is the average speed and the average velocity? (V represents average speed and ΔV represents average velocity)
For the student that walks to the right 25 m in 15 s and then turns and walks to the left 15 m in 8.0 s, we have:
1. The average speed is 1.74 m.
2. The average velocity is 1.42 m.
1. The average speed is an scalar wich is given by:
[tex] V = \frac{d_{t}}{t_{t}} [/tex]
Where:
[tex]d_{t}[/tex]: is the total distance
[tex]t_{t}[/tex]: is the total time
The total distance and the total time can be calculated as follows:
[tex]d_{t} = d_{1} + d_{2} = 25 m + 15 m = 40 m [/tex]
[tex] t_{t} = t_{1} + t_{2} = 15 s + 8.0 s = 23 s [/tex]
Since V is a scalar, the direction of motion is not important to calculate the final value.
Then, the average speed is:
[tex] V = \frac{d_{t}}{t_{t}} =\frac{40 m}{23 s} = 1.74 m/s [/tex]
2. The average velocity is a vector, so the direction of motion is important here. This ΔV can be calculated with the following equation:
[tex] \Delta V = \frac{\Delta x}{\Delta t} = \frac{x_{f} - x_{i}}{t_{f} - t_{i}} [/tex]
Where:
x: is the displacement
f: is for final and i: is for initial
Hence, the average velocity is:
[tex] \Delta V = \frac{x_{f} - x_{i}}{t_{f} - t_{i}} = \frac{15 m - 25 m}{8.0 s - 15 s} = 1.42 m/s [/tex]

why frequency remains unchanged during reflection
Answer:
Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases.
Answer:
When waves travel from one medium to another the frequency never changes.
Explanation:
As waves travel into the denser medium, they slow down and wavelength decreases. Part of the wave travels faster for longer causing the wave to turn. The wave is slower but the wavelength is shorter meaning frequency remains the same.

Please answer this. .
Answer:
a. Mucous membranes protect the inside parts of your body that are exposed to air, in a similar fashion to how your skin protects your external body. Mucous membranes are rich with mucous glands that secrete mucus to help keep the membranes moist.
b.Nose hairs act as a filter that prevents dust, pollen, and allergens from entering your lungs. When particles enter your nose, they get stuck on a thin layer of mucus that coats your hairs. Eventually, the particles either get sneezed out or swallowed. Your nose is also filled with microscopic hairs called cilia.
.
c.The epiglottis is a small, movable "lid" just above the larynx that prevents food and drink from entering your windpipe. But if the epiglottis becomes swollen — either from infection or from injury — the airway narrows and may become completely blocked.
d.Coughing can have causes that aren't due to underlying disease. Examples include normal clearing of airways, irritants such as smoke and gas, tobacco use or improperly swallowing food and liquids.
e.In humans there are about 15 – 20 incomplete C-shaped cartilaginous rings which reinforces the anterior and lateral sides of the trachea to protect and maintain the airway open. (The cartilaginous rings are incomplete because this allows the trachea to collapse slightly to allow food to pass down the esophagus.
f. .Pulmonary surfactant is a surface active material composed of lipids and proteins which is found in the fluid lining the alveoli.
g.The pleura includes two thin layers of tissue that protect and cushion the lungs. ... The very thin space between the layers is called the pleural cavity. A liquid, called pleural fluid, lubricates the pleural cavity so that the two layers of pleural tissue can slide against each other.
h.The ribs are the bony framework of the thoracic cavity. The ribs form the main structure of the thoracic cage protecting the thoracic organs, however their main function is to aid respiration. There are twelve pairs of ribs. Each rib articulates posteriorly with two thoracic vertebrae by the costovertebral joint.

A dog runs 20 m east and then 35 m west in 12 seconds.
What is the dog speed? What is the dogs velocity?
Answer: Dog's speed = (20 + 35) /12 = 4.583 m/s
Dog's velocity = (20-35)/12 = -1.25 m/s
Explanation: Speed is a scalar quantity so we don't care about direction which means we add the magnitude of both the directions i.e. east and west.
About the velocity, it's a vector quantity. So, we must be very careful with the directions and signs. In cartesian coordinates system, we generally take the right side of origin as the positive x-axis and the left side of origin as the negative x-axis. So, considering the same fact, we consider east as positive side and west as the negative side.
Therefore, when we add 20m + (-35m), we get = -15m and you already have the time period of 12 s.
