how does the value of g on the earth is related to the mass of the earth and its radius drive it
The relationship between acceleration due to gravity (g), mass of earth (M) and the radius of earth (R) is [tex]g = \frac{GM}{R^2} [/tex].
What is weight of an object?
The weight of an object is determined as the product of the object's mass and acceleration due to gravity.
F = mg
The gravitational force on objects in the universeThe gravitational force between two objects in the universe is directly proportional to the product of mass of the objects and inversely proportional to the square of the distance between the objects.
[tex]F = \frac{GmM}{R^2} [/tex]
[tex]mg = \frac{GmM}{R^2} \\\\ g = \frac{GM}{R^2} [/tex]
where;
M is the mass of the earth
R is the radius of the earth
Thus, the relationship between acceleration due to gravity (g), mass of earth (M) and the radius of earth (R) is [tex]g = \frac{GM}{R^2} [/tex].

3.How many moles of CO2 gas are in a 101.25 L container filled with CO2 gas?
4.What is the mass of 13.7 moles of N2 gas?
5.How many moles are in 78.5 molecules of CaCO3?
Answer:
1. 39.997 g/mol
2. 6.022⋅1023 atoms of aluminium
3. 0.026 moles
4. 14 grams is the molar mass of nitrogen meaning that one mole of nitrogen atoms is 14 grams. One mole of any substance has 6.02*10^23 atoms/molecules of that subtance therefore there are 6.02*10^23 atoms of nitrogen in 14g of nitrogen
5. 78.5

Copper has a density of 8.96 g/cm^3. What is the mass of a piece of copper with a volume of 2.62 cm^3?
Answer:
23.48
Explanation:
Good Luck!
Answer: 23.48 g
Explanation:
formula: mass = density x volume
Volume of copper = 2.62 cm^3
Density of copper = 8.96 g/cm^3
mass = 8.96 x 2.62 = 23.4752
Why are ionic compounds not considered to be molecules?
Answer:
No, ionic compounds are crystals of infinite cations and anions bound together. There is no “molecule” of ionic compounds such as, for example, NaCl, because there are no single units of the compound.
Explanation:
Ionic compounds are not considered to be molecules because they do not consist of discrete, covalently bonded units like molecules.
In ionic compounds, the bonding occurs through the transfer of electrons from one atom to another, resulting in the formation of ions. These ions are held together by strong electrostatic attractions, known as ionic bonds.
Unlike molecules, which are formed by the sharing of electrons in covalent bonds, ionic compounds do not have individual units with fixed numbers of atoms. Instead, they exist as a three-dimensional lattice structure composed of alternating positive and negative ions. The ions are arranged in a repeating pattern throughout the crystal lattice.

100 ml of nitrogen collected at 27 degree celcius cooled to -73 degree celcius at same pressure.calculate the contraction in volume.
Explanation:
P1. V1/T1 = P2. V2/T2
Apply this
since here, P1 = P2
100 ml / 300 = V2/ 200
==> 100*200/300 = V2
===> V2 = 66.66 ml

What is the mass number (A) of an atom that has an atomic number (Z=26) with 29 neutrons and 26 electrons?
Answer:
A = 55
Explanation:
The atomic number is the number of protons also = the number of electrons, so basically we have 29 neutrons, 26 electrons and 26 protons. Anyway, it's asking the mass number which is the neutrons + the protons, so you just take 29+26 = 55
Atomic number=26
Neutrons=29
Electrons=26
Mass number=Proton+neutron
Protons=26
Mass number=26+29
=55

La energía cinética está relacionada con la velocidad de las partículas.
Sabemos que la velocidad de las moléculas de gas depende de la temperatura del cuerpo. La temperatura de un cuerpo es una medida de la energía cinética promedio de las moléculas del cuerpo.
Debemos notar que cuanto mayor es la temperatura del cuerpo, mayor es la velocidad de sus moléculas. Por lo tanto, a una temperatura de 10,000,000 ° C, las moléculas en el núcleo del sol tienen una velocidad mayor que las moléculas en la superficie del sol.
Todas las moléculas, ya sea en el núcleo o en la superficie del sol, se mueven a mayor velocidad que las moléculas de la limonada a una temperatura mucho más baja. La energía cinética está relacionada con la velocidad de las partículas.

Where is the magnetic field strongest?
A. closest to the wire
B. Farthest from the wire
Answer:
In general, the magnetic field is strongest close to the wire and weaker farther away. In fact, the magnetic field weakens as 1/r1/r where rr is the distance from the wire. This can change a bit depending on the length and shape of the wire. Far enough away, the magnetic field decays as 1/r21/r2 .
Answer:
Closest to the wire
Explanation:
In general, the magnetic field is strongest close to the wire and weaker farther away. In fact, the magnetic field weakens as where is the distance from the wire. This can change a bit depending on the length and shape of the wire.
