A 800 kg car zooms away from a red light with an acceleration of 7.6 m/s2. What is the
average net force in Newtons that the car experiences?
Answer:
6080 N
Explanation:
From the question given above, the following data were obtained:
Mass (m) of car = 800 Kg
Acceleration (a) of car = 7.6 m/s²
Force (F) =?
The force experienced by the car can be obtained as illustrated below:
Force (F) = mass (m) × acceleration (a)
F = m × a
F = 800 × 7.6
F = 6080 N
Thus, the experience a force of 6080 N

How many moles would there be in 500,000,000,000 atoms of silver? Show your calculation
and answer in unit
Answer: 3.01 * 10^35
Explanation:
500,000,000,000 * 6.02 * 10^23
There are 3 [tex]\rm \times\;10^3^5[/tex] moles of silver present in the 500,000,000,000 atoms of silver.
According to the concept of molar mass:
1 atom = [tex]\rm 6.023\;\times\;10^2^3[/tex] moles
500,000,000,000 atoms of silver can be written as:
5 [tex]\rm \times\;10^1^1[/tex] atoms of silver.
1 atom = [tex]\rm 6.023\;\times\;10^2^3[/tex] moles
5 [tex]\rm \times\;10^1^1[/tex] atoms = 5 [tex]\rm \times\;10^1^1[/tex] [tex]\times[/tex] [tex]\rm 6.023\;\times\;10^2^3[/tex] moles
5 [tex]\rm \times\;10^1^1[/tex] atoms = 30.115 [tex]\rm \times\;10^3^4[/tex] moles
= 3 [tex]\rm \times\;10^3^5[/tex] moles.
The moles of silver are present in the 500,000,000,000 atoms of silver are 3 [tex]\rm \times\;10^3^5[/tex] moles.

give me examples of everyday problems you think involve the green substances copper acetate or copper sulfate.
Answer: Copper sulfate is also called blue vitriol, Roman vitriol, Salzburg vitriol, blue copperas or bluestone, which is an inorganic or chemical compound comprised of Copper, Sulphur and Oxygen. It is an odorless crystalline substance, electric blue and highly toxic, which is produced in industries by treating the copper metal with hot concentrated sulfuric acid or treating its oxides with dilute sulfuric acid. It can be produced by slowly leaching low-grade copper ore in air and bacteria may be used to hasten the process.

Thermal energy is a form of... A. kinetic energy. B. electrical energy. C. potential energy. D. chemical energy.
Answer:
A. Kinetic Energy
Explanation:
Thermal energy is when the molecules and atoms are vibrating faster due to higher temperatures.
Kinetic energy fits this because the meaning of it is the energy of a moving object.
Since thermal energy comes from moving molecules and atoms, it is therefore a for of kinetic energy.
Words made from letters of the alphabet are similar to molecules made from atoms. Based on what you already know about matter, which statement best explains this comparison?
A. Atoms can make many different molecules, just like letters can make many different words.
B. Molecules must contain many different atoms, just like words must contain many different letters.
C. There are 26 different atoms that are used to form molecules, just like there are 26 different letters that are used to form words.
D. There are no rules for how letters combine to make words, just like there are no rules for how atoms combine to make molecules.
To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. The correct option is option A.
What is atom?
Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit. Atoms can make many different molecules, just like letters can make many different words.
In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron.
Therefore, the correct option is option A that is Atoms can make many different molecules, just like letters can make many different words.

particles?
Answer:
This question is incomplete
Explanation:
This question is incomplete but one can assume the answer from the definition of quantum mechanics. Quantum mechanics is the science that describes particles in nature at the atomic and subatomic particle (electron, proton and neutron) level. Thus it can be assumed that atoms and subatomic particles are used to broadly describe particles.
