To make your formula neater:
Acceleration is equal to
,
so when you multiply it by time, you will get a velocity. In fact, you would get the change in velocity, as a*t signifies the acceleration of the object over the time, aka the change in velocity.
The initial velocity plus the change in velocity will equal the final velocity, irregardless if the change in velocity is positive or negative.
Therefore,
Answer:
I. Models are always wrong unless they are proved by a theory. TRUE
II. Elements, such as lead, are made of tiny particles that mostly consist of open space. FALSE
III. The air you breathe is an example of a heterogeneous mixture. FALSE
IV. An isotope of silver-108 has 61 neutrons. TRUE
Explanation:
I. All models are wrong because in order for them to be applied to reality, certain aspects that do not fit the theory must be considered.
II. All elements are made by atoms.
III. The air is an example of a homogeneous mixture of different gases. IA homogeneous system is that material system that has the same intensive properties in any part of that system. One way to check it is by viewing it. If the different parts that make it up cannot be distinguished, it will be homogeneous.
IV. Atomic number of Silver is 47. So if its mass number is 108, it has 61 neutrons and 47 protons
Answer:Developed the Bohr model of the atom, in which he proposed that energy levels of electrons are discrete- Niels Bohr
Discovery of energy quanta made him the originator of quantum theory -Max Plank
Formulated the wave equation; stationary and time-dependent Schrödinger equation- Erwin Schrödinger
Best known to the general public for his "mass–energy equivalence formula" ; E = mc^2-B Albert Einstein
Postulated the wave nature of electrons and suggested that all matter has wave properties- Louis de Broglie
Explanation:
All the names mentioned above contributed towards the development of the wave mechanical model of the atom. Their names were matched with their contributions as required by the question.
