What does the mass of an object depend on?
Answer:
the mass of an object depends on inertia greater is the inertia greater will be the mass or vice versa
Explanation:
hope it help ^_^
Mass is the most basic property of matter and it is one of the fundamental quantities. Mass is defined as the amount of matter present in a body. The SI unit of mass is the kilogram (kg). The formula of mass can be written as:
Mass = Density × Volume
The mass of a body is constant; it doesn’t change at any time. Only in certain extreme cases when a huge amount of energy is given or taken from a body, the mass may be impacted. For example, in a nuclear reaction, a tiny amount of matter is converted into a huge amount of energy, this reduces the mass of the substance.
There are various units for calculating mass, like, kilograms, grams, lbs, pounds, etc., but the SI unit of mass is "kilograms" or kg. Every unit of mass can be converted to other units by using a proper conversion formula without affecting the meaning and essence of the quantity to be measured.

What example of scientific thinking does Bohr response best indicate
Answer:
The Bohr model shows the atom as a central nucleus containing protons and neutrons with the electrons in circular orbitals at specific distances from the nucleus (Figure 1). These orbits form electron shells or energy levels, which are a way of visualizing the number of electrons in the various shells

Answer:
GoldExplanation:
A single atom of silver has a total of 47 protons and electrons and 61 neutrons. ... Therefore, gold has a density of 19.32 g/cm3 whereas silver has a density of only 10.49 g/cm3. Thus, a 1 oz bar of gold will be almost half as large as a 1 oz bar of silverwhy are group viia elements very active nonmetals

A given volume of methane diffuses in 20 seconds How long will it take the
same volume of sulphur (IV) oxide to
diffuse under the same condition
(Methane = 16, Sulphur (IV) oxide=64)
Explanation:
Relative molecular mass of CH4 = 12 * 1 + 4 = 16
Relative molecular mass of SO2 = 32 + 10 *2 = 64
tSO2/tCH4 = √MSO2/MCH4
t/20 = √64/16 = √4
t/20 = 2
∴ t = 20 * 2 = 40sec
What does a straight line represent on a distance vs time graph?
Answer:
It represents the relationship between the distance travelled and time spent as constant or at a stop.
Explanation:
This is because as the line progresses, the time increases the distance should change as well my moving up or down, in a linear equation this relationship is constand but if the line is horizontal though, the distance is not changing despite time passing which means it has come to a stop.

Briefly summarize how heavy elements are created
Answer:
Heavy elements are created by fusing two elements together in a lab. They look for “events” that comprise a series of alpha decays that result in spontaneous fission.
Explanation:
Atoms of different element can not have same atomic number because only same type of atoms combine to form element. Atoms belonging to different element can have different atomic number. Therefore, in below given ways we can summarize how heavy elements are created.
What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.
Elements heavier than iron cannot be created by fusion because the reaction requires energy to occur. We do, however, perceive elements other than iron all around us. This is accomplished by supernova explosions, which result in neutron capture processes and the production of heavy materials.
Therefore, in above ways we can summarize how heavy elements are created.

An experiment was conducted to find the mass of one mole of carbon atoms. The results of the experiment showed that a mole of carbon atoms had a mass of 15.78 g. The accepted value of a mole of carbon atoms is 16.00 grams. What is the percent error in this experiment?
Answer:
1.375%
Explanation:
Percent Error = measured value - accepted value/ accepted value x 100
Measured Value: 15.78
Accepted Value: 16.00
Work:
[tex]\frac{15.78-16.00}{16.00}[/tex] * 100
[tex]\frac{-.22}{16}[/tex] * 100 = -1.375
You cannot have a negative percentage. Therefore the answer is 1.375%
