Indicate what a specific property of matter is. Also explain why the specific properties of matter are useful compared to the general ones.

Solution

The specific properties of matter are properties that describes the intensive properties of the system. They are properties that do not depend on or change with the extent or size of the system. They are usually obtained by dividing the generalised properties or extensive properties by the extent or size of matter to make them independent of size/extent/Mass.

Examples of specific properties include specific heat capacity, specific volume etc. They usually have units of general units/Mass units.

The specific properties of matter are more important than the general ones because

- They help in general comparisons of the properties of different materials. They are used to rank, classify and compare properties of different materials.

- They are used in reference table/data to easily record easily accessible properties of matter. It helps to record standards that are general and independent of sizes/extents/Mass, thereby keeping the reference table/data/chart precise and concise.

- They provide us with values that are easy to memorize and remember, unlike trying to cram the different properties of different masses/sizes of matter.

In Spanish/En español

Las propiedades específicas de la materia son propiedades que describen las propiedades intensivas del sistema. Son propiedades que no dependen ni cambian con la extensión o el tamaño del sistema. Por lo general, se obtienen dividiendo las propiedades generalizadas o las propiedades extensivas por la extensión o el tamaño de la materia para hacerlas independientes del tamaño / extensión / masa.

Los ejemplos de propiedades específicas incluyen capacidad calorífica específica, volumen específico, etc. Usualmente tienen unidades de unidades generales / unidades de masa.

Las propiedades específicas de la materia son más importantes que las generales porque

- Ayudan en las comparaciones generales de las propiedades de diferentes materiales. Se utilizan para clasificar, clasificar y comparar propiedades de diferentes materiales.

- Se utilizan en la tabla / datos de referencia para registrar fácilmente propiedades de materia fácilmente accesibles. Ayuda a registrar estándares que son generales e independientes de tamaños / extensiones / masa, manteniendo así la tabla / datos / tabla de referencia precisa y concisa.

- Nos proporcionan valores que son fáciles de memorizar y recordar, a diferencia de tratar de agrupar las diferentes propiedades de diferentes masas / tamaños de materia.

Answer: 366.56 meters.

Explanation:

Velocity of the cannon ball = 425m/s

Velocity of sound = 345 m/s

For the "position" of both, we have the equation:

Pc = 425m/s*t

Ps = 345m/s*t

Where t is time in seconds.

If the position of Chris is X, we have that if the ball reaches the position of Chris in T seconds, then the soundwave reaches the position of Chris in T + 0.20 seconds, we can write this as:

425m/s*T = X

345m/s*(T + 0.20s) = X

Now we can solve this system of equations. First we can replace the first equation in the second equation and get

345m/s*(T - 0.20s) = 425m/s*T

Now we solve this for T.

345*T + 69 = 425*T

69 = (425 - 345)*T = 80*T

T = 69/80 = 0.8625 seconds.

Now we replace this in the first equation and get:

X = 425m/s*T = 425m/s*0.8625s =  366.56 meters.

Answer:

No

Explanation:

She will not be able to measure the length of her window accurately due to instrumental error from her choice of instrument. The elastic nature of her tape would alter the measurement because it will stretch as she is taking her readings, thus reducing the true measurement of the length of her window.

To measure the length of her window, she could use an inelastic tape rule or a metre rule. These instruments would eliminate instrumental error.

Answer:

133.33 mm

Explanation:

First we need to find the volume of the sphere. The volume of a sphere is given by:

V = (4/3) * pi * r^3

With a radius of 10 cm, we have:

V = (4/3) * pi * r^3 = 4188.79 cm3

The sphere will be moulded into a cylinder, so the volume will be the same. The volume of a cylinder is:

V = pi * r^2 * h

Where h is the height of the cylinder, and for this case, it will be the length.

The radius is the same old radius, so we have:

4188.79 = pi * 10^2 * h

h = 4188.79 / 100pi = 13.3333 cm

In millimeters, we have h = 133.33 mm

     Add the negative protons, to make a positive charge. It's just like math a double negative makes a positive.

The first and second velocities of the car, with four washers attached to the pulley, are both 0.125 m/s.

We must apply the following calculations to determine the car's first and second velocities with the four washers attached to the pulley:

v1 = 0.25 m / t1

v2 = 0.25 m / (t2 - t1)

Here, t1 denotes the typical time needed for the car to go 0.25 metres, and t2 is the typical time needed to travel 0.50 metres.Let's say that t1 and t2 are the typical times, each lasting two seconds on average.The first formula allows us to determine v1:

v1 = 0.25 m / 2 s = 0.125 m/s

Using the second formula, we can calculate v2:

v2 = 0.25 m / (4 s - 2 s) = 0.125 m/s

Table E can be used to record these values as the velocities at the relevant distances.

Answer:

 R (120) = 940Ω

Explanation:

The variation in resistance with temperature is linear in metals

           ΔR (T) = R₀ α ΔT

where α is the coefficient of variation of resistance with temperature, in this case α = -0,0005 / ºC

let's calculate

            ΔR = 1000 (-0,0005) (120-0)

            ΔR = -60 Ω

            ΔR = R (120) + R (0) = -60

            R (120) = -60 + R (0)

            R (120) = -60 + 1000

            R (120) = 940Ω

- Determine the number of protons and neutrons in the nucleus of the atom of beryllium.

- Determine the structure of the nuclei of the isotopes of uranium and thorium

- Which forces are called nuclear forces.

- List the peculiarities of nuclear forces.

Solution

Note that the number of protons in the nucleus of an atom is the atomic number of that atom.

And the mass number of the atom is the sum of protons and neutrons in the nucleus of the atom.

The nucleus of an atom is the most massive part of an atom containing almost exclusively the neutrons and the protons of the atom.

- Beryllium has an atomic number of 4 and a mass number of 9.

Hence, its number of protons = atomic number = 4

(Number of protons) + (Number of neutrons) = mass number

Number of neutrons

= (mass number) - (Number of protons)

= 9 - 4 = 5

- Uranium has atomic number of 92 and mass number of 238.

Number of protons = 92

Number of neutrons = 238 - 92 = 146

Thorium has atomic number of 90 and a mass number of 232.

Number of protons = 90

Number of neutrons = 232 - 90 = 142 neutrons.

- Nuclear forces are the forces that keep the neutrons and protons of an atom bonded to the nucleus of an atom. The constituents of the atom's nucleus are called nucleons. Nuclear forces are the forces between two or more nucleons.

- The nuclear forces are about 10 million times stronger than the forces that bind atoms together in molecules and compounds.

Hence, massive energies are required to break into the nucleus of atoms.

This is why nuclear reactors produce about a million times more energy per kilogram fuel compared to chemical fuel.

However, the range of the nuclear force is short, only about 10⁻¹⁵ m, beyond which it decreases rapidly.

This is why, in spite of its enormous strength, we do not feel anything of this force on the atomic scale or in everyday life.

In Romanian/In limba romana

Rețineți că numărul protonilor din nucleul unui atom este numărul atomic al acelui atom. Și numărul de masă al atomului este suma protonilor și neutronilor din nucleul atomului. Nucleul unui atom este partea cea mai masivă a unui atom care conține aproape exclusiv neutroni și protonii atomului.

- Beriliu are un număr atomic de 4 și un număr de masă de 9.

Prin urmare, numărul său de protoni = numărul atomic = 4

(Număr de protoni) + (Număr de neutroni) = număr de masă

Numărul de neutroni = (număr de masă) - (Număr de protoni) = 9 - 4 = 5

- Uraniul are numărul atomic de 92 și numărul de masă de 238.

Numărul de protoni = 92

Numărul de neutroni = 238 - 92 = 146

Toriul are un număr atomic de 90 și un număr de masă de 232.

Numărul de protoni = 90

Numărul de neutroni = 232 - 90 = 142 neutroni.

- Forțele nucleare sunt forțele care mențin neutronii și protonii unui atom legați de nucleul unui atom.

Constituenții nucleului atomului se numesc nucleoni. Forțele nucleare sunt forțele dintre doi sau mai mulți nucleoni.

- Forțele nucleare sunt de aproximativ 10 milioane de ori mai puternice decât forțele care leagă atomii împreună în molecule și compuși.

Prin urmare, energiile masive sunt necesare pentru a pătrunde în nucleul atomilor.

Acesta este motivul pentru care reactoarele nucleare produc aproximativ un milion de ori mai multă energie pe kilogram de combustibil în comparație cu combustibilul chimic.

Cu toate acestea, domeniul forței nucleare este scurt, doar aproximativ 10⁻¹⁵ m, dincolo de care scade rapid.

Acesta este motivul pentru care, în ciuda puterii sale enorme, nu simțim nimic din această forță pe scara atomică sau în viața de zi cu zi.

Answer:20kgm/s

Explanation:

Mass=10kg

Velocity=2m/s

Momentum=mass x velocity

Momentum=10 x 2

Momentum=20

Momentum=20kgm/s

The object with mass m when moving with the velocity, its momentum can be calculated. The momentum of the object A is 20 kg.m/s.

Momentum is the product of mass and velocity of a moving object.

If the momentum is p, the mass of the object is 10 kg and the velocity is 2.0 m/s, then the momentum will be

p = 10 × 2.0

p = 20 kg.m/s

The answer is "C. 3.0 ohms". 

Explanation:

Ohm's law states the following:,

V = IR

where:

Voltage (V) = 1.5 volts × 4 batteries = 6.0 volts

Current (I) = 2.0 amps

Resistance (R) = ? ohms

To solve for Resistance (R) the equation must be rearranged this way:

 R = V / I

Then, the variables must be replaced with the known values:

 R = 6.0 volts / 2.0 amp

R = 3.0 ohms

The answer is  C. 3.0 ohms.
