they will both do the exact same thing, as long as they are bothh identical
Answer:
C. A ball dropped from a height of 10 m will hit the ground at a higher speed than an identical ball dropped from a height of 5 m.
Explanation:
The statement of the hypothesis is that " the greater the height from which you drop a ball, the faster the ball will be traveling when it hits the ground because gravity has more time to speed it up ".
The hypothesis statement is quite explicit. We can deduce that objects at a higher height above the ground will hit the ground much more faster and harder compared to those at a shorter height.
A ball at height of 10m is expected to drop with a higher speed on the ground compared to an identical ball at a height of 5m.
If the balls are at the same height, they are expected to fall with the same speed so far they are identical. Also, a ball at a shorter height will fall at a lower speed.
Answer:
Atomic mass
Explanation:
Atomic mass (Also called Atomic Weight, although this denomination is incorrect, since the mass is property of the body and the weight depends on the gravity) Mass of an atom corresponding to a certain chemical element). The uma (u) is usually used as a unit of measure. Where u.m.a are acronyms that mean "unit of atomic mass". This unit is also usually called Dalton (Da) in honor of the English chemist John Dalton.
It is equivalent to one twelfth of the mass of the nucleus of the most abundant isotope of carbon, carbon-12. It corresponds roughly to the mass of a proton (or a hydrogen atom). It is abbreviated as "uma", although it can also be found by its English acronym "amu" (Atomic Mass Unit). However, the recommended symbol is simply "u".
<u>
The atomic masses of the chemical elements are usually calculated with the weighted average of the masses of the different isotopes</u> of each element taking into account the relative abundance of each of them, which explains the non-correspondence between the atomic mass in umas, of an element, and the number of nucleons that harbors the nucleus of its most common isotope.
In contrast, the atomic mass of an isotope does coincide approximately with the mass of its nucleons. This difference is due to the fact that the elements are not formed by a single isotope but by a mixture with certain abundances for each of them. While when we measure the mass of a particular isotope, we do not take abundance into account. In any case, not even the atomic mass of the isotopes equals the sum of the masses of the nucleons. This is due to mass defect.

Answer:
Arrhenius
H, H₃O⁺
OH, OH⁻
Explanation:
The earliest and simplest definition of acids and bases was suggested by <u>Arrhenius</u>. He/They defined an acid as a substance with <u>hydrogen</u> in its formula that dissociates in water to yield <u>H₃O⁺ </u>and a base as a substance with <u>OH</u> in its formula that dissociates in water to yield<u> OH⁻</u>.
Acid:
An acid is the substance that sour in taste and turns the color of litmus paper from blue to red.
pH of acid is less than seven.
Base:
An acid is the substance that bitter in taste and turns the color of litmus paper from red to blue.
The pH of base is 7-14.
Arrhenius gives the simplest definition of acid and base.
Arrhenius acid:
A substance that increase the concentration of hydronium ion in solution is called acid.
HNO₃ → H⁺ + NO₃⁻
(H₂O)
Arrhenius base:
A substance that increase the concentration of OH⁻ ion in solution is called base.
KOH → K⁺ + OH⁻
