The answer is Element.
Because they are found on the periodic table and they are represented by symbols.
Example: Oxygen; its symbol is O. And it is found in group 16 on the periodic table.
I'm 99% sure that it's "D. Electric Field"
<h2>Right answer: acceleration due to gravity is always the same </h2><h2 />
According to the experiments done and currently verified, in vacuum (this means there is not air or any fluid), all objects in free fall experience the same acceleration, which is <u>the acceleration of gravity</u>.
Now, in this case we are on Earth, so the gravity value is
Note the objects experience the acceleration of gravity regardless of their mass.
Nevertheless, on Earth we have air, hence <u>air resistance</u>, so the afirmation <em>"Free fall is a situation in which the only force acting upon an object is gravity" </em>is not completely true on Earth, unless the following condition is fulfiled:
If the air resistance is <u>too small</u> that we can approximate it to <u>zero</u> in the calculations, then in free fall the objects will accelerate downwards at and hit the ground at approximately the same time.
Answer:
Bluegills are the primary food source in every farm pond. They spawn from May to September and provide a large amount of food to the predators in the pond.
Explanation:
Answer:
A. The one with the circular cross section will stretch more.
Explanation:
According to the given data:
Two rods are made of brass and have the same length
Both rods having circular and square cross-section
Diameter of circular cross-section given is 2 a
therefore, Cross-section =
If the length of square=2 a
then, Cross-section = = (2a)²=>4a²
Change in Length of rod = PL / AE
δL
Now, we are considering other factors same
the area of cross-section of square rod is more than Area of cross-section of circular rod
thus, the one with the circular cross section will stretch more
