The Density of the copper is 8.91 g/cm³.

The density of a substance is obtained from the ratio of the mass and the volume of the substance.

The formula of density is given below:

The mass of the copper is 17.11 g

The volume of the rectangular piece of copper is calculated as:

volume = length * breath * height

Volume of the rectangular piece of copper = (2.13 * 0.79 * 1.14) cm³

Volume of the rectangular piece of copper = 1.92 cm³

Density of the copper = 17.11 g/1.92 cm³

Density of the copper = 8.91 g/cm³

Answer:

Fn = m x g

Fn = normal force

m = mass of the stone

g = gravitational force acting on the stone.

therefore, fn=m x g = 10kg x 9.8m/s2 = 98 kgm/s2 or 98 N. Which is the same as 098 N.

Explanation:

A stone with a mass of 10 kg sits on the ground. The normal force acting on the stone, keeping it at rest, is 98 N. The correct option is D.

A force is a power that changes the position of an object. This results in the action or movement of any object. Force is calculated in Newton. The force can be calculated by multiplying the mass by acceleration.

Given, the mass of the stone is 10 kg

The gravitational force act at the rate of 9.8 m/s²

The formula is

Force  = mass x gravitational rate

Fn = normal force

m = mass of the stone

g = gravitational force acting on the stone

So, fn = m x g

10kg x 9.8 m/s²

98 kg m/s²or 98 N

Therefore, the normal force acting on the stone, keeping it at rest, is 98 N. The correct option is D.

Solid state: In the solid state, the molecules are arranged in a regular and fixed pattern. The molecules in a solid are closely packed that is the solid particles can not move.

Liquid state: In the liquid state, the molecules are present in an irregular pattern. The molecules are closely packed but particles can move.

Gaseous state: In the gaseous state, the molecules are present in an irregular manner. The molecules of gases are not closely packed and can move freely.

Therefore, the solid changes to liquid on heating, and the liquid changes to solid after cooling.

Explanation:

The average speed at which the cars rolled down the track   4.28 m/s

Average Speed is defined as Total Distance Traveled ÷ Total Time Taken . SI unit of average speed is meter per second ( m/s).

Average Speed = total distance traveled ÷ total time taken

we have , jessica's car travelled 40 m in 10 sec

kristi's car travelled 40 m in 20 sec

laticia's car travelled 40m in 8 sec

Average Speed = total distance traveled ÷ total time taken

so,                          = 40+40+40 ÷ 10+20+8

                                  = 120÷28

                                = 4.28 m/s

The correct answer for  relative abundance of isotope 3 is 46.52%.

Let's consider element X, which has 3 isotopes: isotope 1 with a relative abundance of 12.99%, isotope 2  with a relative abundance of 40.49% and isotope with an unknown relative abundance.

Assuming there are only 3 isotopes of element X, we know that the sum of the relative abundances of them is equal to 100%. The relative abundance of isotope 3is:

ab(isotope 1) + ab(isoptope 2) + ab (isotope 3) = 100 %

isotope 3 = 100% - (12.99% + 40.99 % )

isotope 3 = 46.52 %

Element X has 3 isotopes: isotope 1 with a relative abundance of 12.99%, isoptope 2 with a relative abundance of 40.49% and isotope 3 with a relative abundance of  46.52%.

The percentage of atoms with a specific atomic mass found in a naturally occurring sample of an element is known as its relative abundance.

AgNo3 is a polymorph as it can be many forms.

A substance's capacity to crystallize into various crystalline forms is known as polymorphism. These crystal modifications are also referred to as polymorphs. Polymorphs behave differently in the solid state even though they are the same in the liquid or gaseous states.

The ability of some chemical elements to exist in two or more different forms, in the same physical state, is known as allotropy or allotropism. These forms are referred to as the element's allotropes. Allotropes are different structural modifications of an element in which the bonding between the atoms is altered.

If the density of the object is 1.65 g/mL. The object's weight in pounds m = 483.32 pounds.

The density can be defined as the mass per unit volume which can be described it is the ratio between mass and volume.

Density is a measurement of matter, where it determine how tightly the matter is bond together, discovered by the Greek scientist Archimedes.

To calculate the density of an object, Density = Mass/Volume

The density of the object is 1.65 g/mL, Volume of the water is 35.1 gallons

1 gallon = 3785.41 mL

35.1 gallons = 132868 mL

The correct answer is  a sphybridisation in z coordinate.So to form sphybridisation we need a s orbital and a p orbital  .

In genomics, hybridization is the process by which two complementary single-stranded DNA or RNA molecules bond together to form a double-stranded molecule.The bonding is determined by the correct base pairing between the two single-stranded molecules. When one s and one p orbital in the same main shell of an atom combine to form two new equivalent orbitals, this is referred to as sphybridization.

The newly formed orbitals are known as sphybridized orbitals. It forms linear molecules with a 180° angle. Atomic orbitals include both s and p orbitals. These orbitals represent the most likely region in which we can find an electron of that atom. The primary distinction between s and p orbitals is that s orbitals are spherical in shape, whereas p orbitals are dumvell-shaped.So to form  sp hybridisation we need a s orbital and a  p orbital .
