Answer:

In chemistry, orbital hybridization (or hybridization) is the concept of mixing atomic orbitals into new hybrid orbitals (with different energies, shapes, etc., then the component atomic orbitals) suitable for the pairing of electrons to form chemical bonds in valence bond theory.

¡Hellow!

For this problem, first, lets convert the seconds in hours:

5,4x10³[tex]\rightarrow[/tex] 5400

h = sec / 3600

h = 5400 s / 3600

h = 1,5

Let's recabe information:

d (Distance) = 386 km

t (Time) = 1,5 h

v (Velocity) = ?

For calculate velocity, let's applicate formula:

                                                    [tex]\boxed{\boxed{\textbf{d = v * t} } }[/tex]

Reeplace according we information:

386 km = v * 1,5 h

v = 386 km / 1,5 h

v = 257,33 km/h

The velocity of the train is of 257,33 kilometers for hour.

Extra:

For convert km/h to m/s, we divide the velocity of km/h for 3,6:

m/s = km/h / 3,6

Let's reeplace:

m/s = 257,33 km/h / 3,6

m/s = 71,48

Answer:

Speed = 68.75m/s

Explanation:

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the equation;

[tex]Speed = \frac{distance}{time}[/tex]

[tex]S = \frac{d}{t}[/tex]

Given the following data;

Distance = 550m

Time = 8secs

Substituting into the above equation;

[tex]S = \frac{550}{8}[/tex]

Speed, S = 68.75m/s

Explanation:

To be able to solve this type of problems it is always advisable to make a free body diagram with the forces acting on the body.

Attached is an image with the free body diagram and the proposed equations, the explanation of obtaining the equations will be described below.

Let's take the movement to the left as positive, i.e. all forces going to the left have a positive sign.

Let's use Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration.

To the left we have the two forces of tension by the cosine of the angle. And to the right the frictional force. The resultant of these forces is equal to the product of the mass (mass of the child plus the mass of the sled), by acceleration.

Answer:

Newton's second law of motion is quantitative law of force . Newton's first law of motion is qualitative law of force.

Answer:

- For the lithium ion to change to become an anion, it will have to gain one or more electrons which can be pulled away from possibly other atoms with a weaker affinity for them.

- For the lithium ion to change to become a cation, it will have to loose one or more electrons which can be drawn by other atoms with a stronger affinity for them.

Explanation:

Generally, an anion has a net negative charge arising from the fact that it has more electrons than protons while a cation has a net positive charge arising from the fact that it has more protons than electrons.

Now, for the lithium ion to change to an anion, it means it has to have more electrons than it's protons. Thus, since it has 3 number each of protons and electrons, it will have to gain one or more electrons which can be pulled away from possibly other atoms with a weaker affinity for them.

Now, for the lithium ion to change to a cation, it means it has to have more protons than it's electrons. Thus, since it has 3 number each of protons and electrons, it will have to loose one or more electrons which can be drawn out by possibly other atoms with a stronger affinity for them.

The chef can make 8 casseroles

Explanation:

Units Conversion

We need to recall 1 gallon = 16 US cups.

A casserole needs 1 cup of milk, and the chef has 0.5 gallons of milk. Those 0.5 gallons are equivalent to 0.5*16 = 8 cups, thus the chef can make 8 casseroles.

Answer:

2,250 meters deep

Explanation:

If the time taken for the the signal to return to the boat means that it took 3 seconds for the signal to travel to and from the floor the same distance. That means it took 1.5 seconds to travel to the floor at a speed of 1500m/s means that it is 1500 multiplied by 1.5 to a distance of 2,250m. (Derived from the speed = distance divided by time formula to distance = speed multipled by time)

Answer:

The magnitude of the displacement is  [tex]H = 14.14 \ km[/tex]

Explanation:

From the question we are told that

  The distance of the car to north is  d =  10 km

   The distance of car to the west is  w =  - 10 \  km

The negative sign is because the direction is  west

Generally applying Pythagoras theorem , the displacement is  

         [tex]H = \sqrt{d^2 + w^2}[/tex]

=>      [tex]H = \sqrt{(10)^2 + (-10)^2}[/tex]

=>     [tex]H = 14.14 \ km[/tex]

Answer:

4 m/s^2

Explanation:

To get the acceleration you are going to use the acceleration formula which is

Acceleration= Force/Mass.

You then do the math which is 20/5, which equals 4

Therefore you get a value of 4. You may be asking what the units are. The units of acceleration are m/s^2 (meters per second squared)

So your final answer is 4 m/s^2

Answer:

The answer is unbalanced

Explanation:

Though cases like these are not really how the science will be used, they illustrate the principle.

If the left art shows two big dogs pulling on a rope toy each pulling with a force of 20N in the opposite direction. The middle art shows a big dog on left pulling to the left on the rope toy with a force of 20N and a little dog pulling to the right with a force of 12N. The right art shows the rope toy tied to a post, with both dogs pulling on different parts of the toy and in the same direction. One large dog pulls with a force of 20 N and the small dog pulls with a force of 12 N. The atomic theory has been of priceless value to chemists, but it has more than once happened in the history of science that a hypothesis, after having been useful in the discovery Present and the co-ordination of knowledge, has been aban- position doned and replaced by one more in harmony with later of the discoveries

The amount of force exerted in each direction in the rope determines if the force in play is balanced or unbalanced ;

To determine if the force acting in two direction is balanced or unbalanced, we calculate the net force acting on the object.

If the netforce = 0 ; then the force is balanced, if otherwise , then it is unbalanced.

Left art :

Right art :

Middle :

Therefore, the value of the net force determines if the force is balanced or not.

Answer: 112.992

Explanation: If you divide 287 by 2.54, you will get 112.992125984. I just got rid of the five numbers after 992.

1 inch = 2.54 cm

?= 287 cm let, ? be (a)

cross multiply

2.54a= 1×287

a= 287/2.54

a= 112.992126

therefore 287 cm = 112.992126 inches.

It should be the first one, F= mXa (F = m times a).

Li , which is located in group 1 of the periodic table, has one valence electron.

Chlorine, which is in group 17 of the periodic table, has seven valence electrons.

When the two atoms bond, lithium will lose one electron and form the lithium cation,  Li + .

Since it loses one electron 7-1 = 6, there will be 6 valence electrons.

Answer:

t= 4.5s

Explanation:

vi=0m/s

a= 1m/s

d=10m

10m= 0(t) + 1/2(1m/s)(t^2).    0xt cancels out, 1/2 of 1= .5

10m=  .5m/s(t^2)   Divide both sides by .5

20m= t^2.  Take square root of each side

Square root of 20 is 4.472135954999579

Answer:

Energy moves from one place to another through the wave. answer A

A wave is a disturbance that transmit energy. Thus, the correct statement is energy moves from one place to another through the wave.

A wave is a disturbance that transfers energy as it moves from one point to another.

Different terminologies are used to characterise a wave as it travels. Some of these include

Considering the question given above, we see clearly from the definition of wave that the energy is transferred as the wave is moving.
