The repetition of the experiment allows to support the results, therefore the correct answer is:
based on experimental evidence
The theory is a set of rules, principles and knowledge that are developed from models and experiments that are carried out repeatedly, finding similar results in any given case.
In this case, Ellie repeated each experiment several times, finding results that lead to the result that the two balls hit the ground at the same time, therefore her conclusions are supported by experimental evidence.
In conclusion the conclusions of the experiment of dropping the balls the correct answer is: it is based on the experimental evidence

Two objects of masses 50 g and 100 g are moving along the same line and direction with velocities of 5 m/s and
10 m/s respectively. They collide and after collision, the second object moves at a velocity of 8 m/s. Determine
the velocity of the second object.
Answer:
M1 v1 + M2 v2 = M1 V1 + M2 V2
Assuming we are to fine V2 (the problem is not clear on this point)
50 * 5 + 100 * 10 = 50 * 8 + 100 V2 conservation of momentum
V2 = (250 + 1000 - 400) / 100 = 850 / 100 = 8.5 m/s

252 m/s West
238 m/s, West
Answer:
7 m/s East
Explanation:
The speed of the man relative to the plane is given as 7 m/s. Given that he's walking in the corridor of the plane, this is his speed relative to the plane. Since he's moving to the back of the plane, and the aircraft is headed to west, the man's direction relative to the plane is East.

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.

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

what is the relationship between the variables on this graph? The temperature does not have an effect on flow time. As the temperature increases, the flow time increases. As the temperature increases, the flow time decreases.
Answer: As the temperature increases, the flow time increases.
Explanation: i took the test
The relationship between the variables on this graph is that As the temperature increases, the flow time increases, therefore the correct answer is option B.
What is the kelvin scale of temperature?It is a scale of temperature used to measure the temperature, the kelvin scale of temperature is also known as the absolute scale of temperature.
The Standard International unit of thermodynamic temperature is the kelvin, often known less frequently as the degree Kelvin. The formal definition of one kelvin is 1/273.16 of the thermodynamic temperature of pure water's triple point.
As shown in the graph as the temperature increase across the X axis the flow time is increasing as well, these two variables are directly proportional to each other.
Thus, The graph shows a link between the variables, showing that when the temperature rises, flow time also rises, hence option B is the proper response.

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.
