Answer:

Crystallization of solids

Explanation:

What is Crystallization?

Crystallization is a technique used for the purification of substances. A separation technique to separate solids from a solution.

Crystallization can be defined as the process through which the atoms/molecules of a substance arrange themselves in a well-defined three-dimensional lattice and consequently, minimize the overall energy of the system. When a substance is subjected to crystallization, its atoms or molecules bind together through well-defined angles.

On adding a solid substance in a liquid and stirring it, the solid dissolves in the fluid. But when adding more and more solid to the liquid, a point comes after which no more solid dissolves in the liquid. This point is called a saturation point and the fluid is called a saturation solution.

Key words and phrases:

saturation, crystallization, solids, liquids, substance, atoms, molecules, saturation solution, saturation point, purification, separation, solution, dissolve

What is acceleration?

Acceleration can be defined as the change in speed or the direction of the object.

From kinamatic equation:

[tex]D = v_{t} +\dfrac 12at^2[/tex]

Where,

[tex]D[/tex] - final velocity =  445 m/s

[tex]v_0[/tex] -  initial valocity = 0 m/s

[tex]a[/tex] - acceleration = 99. 0 m/s²

[tex]t[/tex] - time =  4. 50 s

Put the values in the formula,

[tex]D = 0\times ( 4.5) + \dfrac12\times (99)(4.5)^2\\\\D = 1002 {\rm \ m}\\\\D = 1 \times 10^3\rm \ m[/tex]

A stationary 25 kg object is located on a table near the surface of the earth. The coefficient of static friction between the surfaces is 0.50 and of kinetic friction is 0.30. A horizontal force of 300 N is applied to the object. Determine the acceleration of the object. *

Answers

The net vertical force on the object is

∑ F[vertical] = n - mg = 0

where n is the magnitude of the normal force exerted by the surface, m is the object's mass, and g is the mag. of acceleration due to gravity. It follows that

n = mg = (25 kg) (9.8 m/s²) = 245 N

The net horizontal force is

∑ F[horizontal] = 300 N - f = ma

where f is the mag. of friction and a is the object's acceleration.

We have

f = µn

where µ is the coefficient of friction. Since the object starts at rest, it won't move and accelerate unless the applied force of 300 N is sufficient to overcome the maximum static friction, which is

f = 0.50 n = 0.50 (245 N) = 122.5 N

Since f < 300 N, the box will begin to slide, at which point the coefficient of kinetic friction kicks in and the mag. of friction is

f = 0.30 n = 0.30 (245 N) = 73.5 N

Now solve for a :

300 N - 73.5 N = (25 kg) a

a = (226.5 N) / (25 kg)

a = 9.06 m/s² ≈ 9.1 m/s²

Two men pull on a 31-kg box with forces 8.3 N and 6.6 N in opposite directions.
Find the resultant acceleration of the box and the direction in which the box moves.

Please HURRY

Answers

Answer:

0.054m/s²

Explanation:

Here we are given that a 31kg block is being pulled by two men who apply forces of 8.3N and 6.6N in opposite directions .

So we know that ,

[tex]\sf \longrightarrow \boxed{\red{\rm F_{net}= \sqrt{F_1^2+F_2^2+2F_1F_2cos\theta }}}[/tex]

where [tex]\theta[/tex] is the angle between the forces .

Since the forces act in opposite directions , the angle between them will be 180° .

[tex]\sf \longrightarrow F_{net}= \sqrt{ (8.3N)^2+(6.6N)^2+2(8.3)(6.6)(cos180^o)}\\ [/tex]

Value of cos 180° = -1

[tex]\sf \longrightarrow F_{net}= \sqrt{ (8.3N)^2+(6.6N)^2+2(8.3)(6.6)(-1)}\\ [/tex]

[tex]\sf \longrightarrow F_{net}= \sqrt{ (8.3N)^2+(6.6N)^2-2(8.3)(6.6)}\\ [/tex]

RHS is in form of (a-b)² = + -2ab inside the square root .

[tex]\sf \longrightarrow F_{net}=\sqrt{( 8.3N - 6.6N)^2} \\ [/tex]

[tex]\sf \longrightarrow F_{net}= 8.3N - 6.6N \\ [/tex]

[tex]\sf \longrightarrow \red{ F_{net}= 1.7N} \\ [/tex]

Now we know that ,

[tex]\sf \longrightarrow F_{net}= mass * acceleration \\ [/tex]

[tex]\sf \longrightarrow 1.7N = 31kg * a\\ [/tex]

[tex]\sf \longrightarrow a =\dfrac{1.7N}{31kg}\\ [/tex]

[tex]\sf \longrightarrow \underline{\boxed{\bf accl^n = 0.054 m/s^2}} \\ [/tex]

And the box will move in the direction of application of 8.3N force .

A trucker drives along a straight highway for 0.25 h with a displacement of 16 km south. What is the trucker’s average velocity?

helping me would b a big help ;)

Answers

The trucker’s average velocity who drives the truck along  a straight highway is 64 km/h in south.

What is average velocity?

Average velocity of a body is the ratio of displacement of a body in the given time. In case of average velocity, the displacement of the body is the same for each interval of time.

Average velocity can be calculated with the following formula.

[tex]\overline v =\dfrac{\Delta x}{\Delta t}[/tex]

Here, Δx is the displacement and Δt is the change in time. The average velocity can be positive or negative.

A trucker drives along a straight highway for 0.25 h with a displacement of 16 km south.

The displacement of the truck is 16 km in the south direction, and change in time to cover this distance is 0.25 hours. Thus, the average velocity of the truck is,

[tex]\overline v =\dfrac{16}{0.25}\\\overline v =64 \rm\; km-h^{-1}[/tex]

Hence, the trucker’s average velocity who drives the truck along  a straight highway is 64 km/h in south.

If one person pushes on an object with a force of 200 N and another person pushes with a force of 150 N in the opposite direction, what is the net force on the object?

Answers

So, their net force on the object is 50 N in a forward direction from the first person.

Introduction

Hi ! Here, I will help you with the net forces (results of forces) acting on a two-dimensional area and in opposite directions. Steps that can be taken are as follows :

Determine where the force will go, the important thing is that you are consistent until the end. Count the values of the force acting, the force against the direction of your mind in number 1 is given a negative sign.Look at the results, if it's marked (-), then choose the opposite direction from your thoughts at number 1.

The equation for calculating the net force from this two-dimensional straight line is as follows:

[tex] \boxed{\sf{\bold{\sum F = F_1 + F_2 + ... + F_n}}} [/tex]

With the following condition :

[tex] \sf{\sum F} [/tex] = net force (N)[tex] \sf{F_1} [/tex] = first force and its direction (N)[tex] \sf{F_2} [/tex] = second force and its direction (N)[tex] \sf{... + F_n} [/tex] = You can add up the force values as many times as the question (N).

Problem Solving

We know that :

In my mind, I determined that the force will go to forward direction from the first person. So :

[tex] \sf{F_1} [/tex] = first person force = 200 N >> Because he is the frame of reference.[tex] \sf{F_2} [/tex] = second person force = -150 N >> Because he against the direction of the frame of reference (first person)

What was asked :

[tex] \sf{\sum F} [/tex] = net force = ... N

Step by step :

[tex] \sf{\sum F = F_1 + F_2} [/tex]

[tex] \sf{\sum F = 200 + (-150)} [/tex]

[tex] \sf{\sum F = 200 - 150} [/tex]

[tex] \boxed{\sf{\sum F = 50 \: N} [/tex]

Conclusion

The movement of the object is forward (from the first person) because the net force value that I calculated is not opposite (with negative sign) to the right direction. So, their net force on the object is 50 N to the forward direction from first person.

New technologies, especially IT with the huge number of modern applications, has almost become synonymous with what we call development. Every country that looks forward to development (economic, technological, etc.) is literally "hooked" by new technologies: it has introduced them in Education, strengthens their research, finances their applications, promotes in every way everything related to with them, especially with PC technology. What may not have been more deeply realized, especially in Greece, is the importance of new technologies for a quality education that is the prerequisite for any form of development of a country.B. The benefits that are expected for our Education, if properly implemented programs with appropriate educational software, are mainly the following: First, to be able to enter large libraries, foreign and Greek and to obtain the information needed, to study articles in magazines. In addition, use training programs with a combination of image - audio and text. With this technology the cultural or national lessons of a country's education system can be taught in new attractive, renewed and meaningful ways. Thus, by teaching the history of a period, you can, together with the information about the events and persons, present maps, paths, relations, parallel events of the history of neighboring countries, at the same time give information about literature, sciences, arts, tradition. , religion, the language of a people with image, with sound and of course with text.C. Such programs can work in cultural courses, aesthetics courses and knowledge courses. But the most important thing is that with such programs, the School and in general the Education and the provided Education, can regain the interest that is needed to attract the love and the essential participation of the students. It is equally important that such programs can certainly be the starting point of a radical renewal of the educational system of Greece and its reopening on new bases.D. With the introduction of new technologies in the School, the role of the teacher and the teacher in general changes completely. To date teacher and textbooks have been the main source of information.
