The formula relevant for this is:
h = v0t + 0.5 gt^2
since the rock was dropped, therefore:
h = 0.5 gt^2
we can see that:
h / t^2 = 0.5 g = constant
therefore:
4.9 m / (1 s)^2 = h / (3 s)^2
<span>h = 44.1 m </span>
Answer:
Correct answer: V₀ = 10 m/s
Explanation:
Depending on time and acceleration, the distance formula is:
D = V₀t + a t²/2
in accordance with the given formula we conclude that the
initial velocity is V₀ = 10 m / s

<u>Question:
</u>
The law of conservation of mass follows from the concept that a. atoms are indivisible. b. atoms of different elements have different properties. c. matter is composed of atoms. d. atoms can be destroyed in chemical reactions.
<u>Answer:</u>
The law of conservation of mass follows from the concept that atoms are indivisible
<u>Explanation:
</u>
The law of conservation of mass tells that atoms in an object neither can be created nor be destroyed, but they can be transferred around and transformed into various particles. Also, it says that the total mass preceding the chemical reaction corresponds to the total mass after the chemical reaction.
In other words, the mass remains intact. Lavoisier formulated this law as a result of a combustion experiment in which he stated that the weight of his starting material - a glass jar, tin and air - was equal to the mass of the material produced - a glass jar, "Tin calcium" and the rest of the air.
The term "atom" arrives from the language of Greek and means indivisible, because atoms were thought to be the tiny things present in the universe and could not be divided. But not familiar that atom comprises with three particles: proton, neutron and electron- even tiny particles like quarks.
