What type of rays result in shorter days? (science)

Answers

Answer 1

Answer:

verical rays

Explanation:

Answer 2

The rays result in shorter days are the vertical rays.

What are vertical rays ?

Vertical rays are another name for direct rays. Rays that are straight overhead are referred to as vertical. Because the Earth is spherical, not all the Sun's rays hit it directly or vertically.

Vertical rays lose less heat because they cover a shorter distance. Slanted rays cover more ground and dissipate more heat. Sun's vertical rays fall between the Tropics of Cancer and Capricorn, along its migratory belt.

The length of a day is determined by the Earth's rotation around its axis, which has been accelerating during the past several decades. Our days have been becoming shorter due to this tendency.

Thus, vertical rays are responsible for shorter days.

There are no transition elements between the Group 2 element magnesium and the
Group 3 element aluminium.
Give a reason why, in terms of electronic structure.

Answers

Answer:

Atomic orbital energy ordering.

Explanation:

The transition metals constitute the d-block. The answer to your question has to do with the energy ordering of atomic orbitals. Specifically, the 3s orbitals are lower in energy than 3p, which are lower in energy than 4s, which are lower in energy than 3d (remember the principal quantum number for d orbitals is one minus the principle quantum number of the shell so n = 4 level's d orbitals are the 3d orbitals). According to the Aufbau principle, atomic orbitals are filled with electrons from the lowest energy up. So the orbitals would have to be filled in the order of 3s, 3p, 4s, and then 3d. Magnesium has its last valence electron residing in the 3s orbital and Aluminum has its last valence electron residing in the first 3p orbital (specifically the 3px orbital, which is aligned horizontally in the 3d plane. The three p orbitals for all principle quantum levels are px, py, pz, with the x, y, z describing the orientation in the 3d plane). The 3d has not yet been reached in terms of energy ordering. This is why there are no transition elements between magnesium and aluminum, in terms of electronic structure.

paragraph, create an imaginary example of finding a given amount of Lokium and
DOL in a rock, and then determining the absolute age of that rock. Assume that
each trial represents 1,000 years

Answers

Answer:

The situation given here is imaginary such that the life of Rock has to be found using the half-life of the element lokium that has been found inside the rock.

Half-life of any material is the amount of time taken by that particular material to decay. Now the amount of lokium found in rock can show after how many half-lives this amount has been left out.

The time elapsed will be log (L) atoms X half-life.

0.5

Answers

Considerando la definición de molaridad, la molaridad de una solución acuosa de ácido sulfúrico (H₂SO₄) es 0.5 [tex]\frac{moles}{litro}[/tex].

La molaridad es una medida de la concentración de un soluto en una disolución que se define como el número de moles de soluto que están disueltos en un determinado volumen.

La molaridad de una solución se calcula dividiendo los moles del soluto por el volumen de la solución:

[tex]Molaridad=\frac{numero de moles de soluto}{volumen}[/tex]

La Molaridad se expresa en las unidades [tex]\frac{moles}{litro}[/tex].

En este caso, sabes que una solución acuosa se preparó al mezclar 4 moles del ácido con suficiente agua hasta completar 8 litros de solución. Entonces, sabes que:

número de moles de soluto= 4 molesvolumen= 8 litros

Reemplazando en la definición de molaridad:

[tex]Molaridad=\frac{4 moles}{8 litros}[/tex]

Resolviendo:

Molaridad= 0.5 [tex]\frac{moles}{litro}[/tex]

Finalmente, la molaridad de una solución acuosa de ácido sulfúrico (H₂SO₄) es 0.5 [tex]\frac{moles}{litro}[/tex].

what are the uses of the periodic table​

Answers

Answer:

In today's world, the periodic table is very valuable for both students and scientists since it allows them to forecast the sorts of chemical reactions in which a specific element is likely to engage. Rather than memorizing facts and figures for each element, students and scientists can learn a great deal by simply looking at the table. They can learn about an element's reactivity, whether it is likely to conduct electricity, whether it is hard or soft, and many other characteristics by simply looking at the table.

Groups are made up of elements that are in the same column as one another and have attributes that are comparable to one another. If we look at the first column (the alkali metals), for example, we see that they are all metals that have a 1+ charge in reactions, react quickly with water and combine easily with nonmetals.

Periods are made up of elements that are arranged in a row next to one another and have the same maximum unexcited electron energy level as one another.

The periodic table also has the advantage of providing all the information you need to balance chemical processes at a glance, which is a very valuable feature. The atomic number and, in most cases, the atomic weight of each element are included in the table. The group of an element indicates the characteristic charge of that element.

All the given elements are representative elements as they have valence electrons present in p -orbital except option a which has valence electron d-orbital and hence is not a representative element.

It is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.

Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.

The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

Thus, all the given elements are representative elements as they have valence electrons present in p -orbital except option a which has valence electron d-orbital and hence is not a representative element.

If two trucks are moving at the same speed, but truck A has a mass of 3,000 kg, and truck B has a mass of 4,500 kg, what statement is true?

Question 3 options:

Truck B will have a greater stopping distance.


Truck A will have a greater stopping distance.


Truck B has less kinetic energy.


Truck A has greater kinetic energy.

Answers

We want to compare the kinetic energy of two moving objects, we will see that the correct option is the first one:

"Truck B will have a greater stopping distance."

Remember that the kinetic energy of an object of mass M and velocity V is given by:

[tex]E = \frac{M}{2}*V^2[/tex]

Here we know that truck A and truck B have the same velocity, but truck B has a larger mass.

Knowing that the kinetic energy increases linearly with the mass, we can conclude that truck B has the largest kinetic energy.

Because of this, we can also conclude that truck B will have a greater stopping distance, this happens because there is more kinetic energy that must be dissipated.

So the correct option is the first one:

"Truck B will have a greater stopping distance."

A student graphed the position of a cart during a 7-second time interval.
Which statement best describes the cart?

A.
The cart was stationary except for a short burst of acceleration of 0.5 m/s².

B.
The cart accelerated at a constant rate of approximately 0.8 m/s².

C.
The cart was stationary with a velocity of 0 m/s for the entire 7 seconds.

D.
The cart moved at a constant velocity of 0.5 m/s for the entire 7 seconds.

Answers

Hi!
Answer: D the cart moved at a constant velocity of 0.5m/s for the entire 7 seconds.

The cart accelerated at a constant rate of approximately 0.8 m/s². Option (B) is correct.

Option B is the best description based on the graphed position data during the 7-second time interval. The cart's acceleration can be determined by analyzing the shape of the position-time graph.

If the cart was stationary, the position-time graph would be a horizontal line (option C). If the cart moved at a constant velocity, the graph would be a straight line inclined at a constant angle (option D).

However, the graph likely shows a curved line, indicating changing position over time. This suggests that the cart experienced acceleration. To further confirm, calculate the acceleration:

Acceleration (a) = Δv / Δt,

where Δv is the change in velocity and Δt is the change in time.

Given the time interval is 7 seconds, and the initial and final velocities are likely different, you can calculate the average acceleration. If the average acceleration is approximately 0.8 m/s², then option B is correct.

The graphed data aligns with the scenario of constant acceleration, supporting option B.
