Explanation:

There are two forces acting upon the book. One force - the Earth's gravitational pull - exerts a downward force. The other force - the push of the table on the book (sometimes referred to as a normal force) - pushes upward on the book.

There are mainly 3 forces which acts on a book.

Listed below are the forces and their points:-

• Earth's Gravitational force of attraction- Usually, we may not consider or notice this force, but when a book falls, we understand this, because the book falls due to this gravitational force.

• Force exerted on book while pushing it- While we push a book, we apply Push Force, due to which the book moves on the pushing it on a table.

• Frictional Force- We notice that while pushing a book, it does not continuously move in motion. At a certain distance, this Frictional force increases and therefore, the book comes to a halt.

Location- Opposite of exerted force in all directions

Answer:

Although expansion seems to imply a Big Bang, no other specific predictions of the Big Bang theory were tested and confirmed until the 1960s.  

Explanation:

Answer:

Today, the consensus among scientists, astronomers and cosmologists is that the Universe as we know it was created in a massive explosion that not only created the majority of matter, but the physical laws that govern our ever-expanding cosmos.  This is known as The Big Bang Theory. For almost a century, the term has been bandied about by scholars and non-scholars alike. This should come as no surprise, seeing as how it is the most accepted theory of our origins.

Hey there! Here's your answer:

10 km

Here's why:

The bus's displacement has two components, a number of km and the direction of the final position from the initial position.

The bus's displacement is the hypotenuse of the triangle, 10 km southeast of the initial position.

But southeast is only a rough estimate of the direction.

The tangent of the angle is 6/8 or .75, so the amount of angle to the east of south is 37 degrees.

South (180 degrees) minus 37 degrees is 143 degrees.

The car’s displacement is more accurately called 10 km in a direction of 143 degrees from the initial point.

Have a good day!

Answer:

An ionic bond is likely because they will want to give away two valence electrons in order to become stable.

Considering the octet rule and the definition of ionic bond,   the correct option is the second option: "An ionic bond is likely because they will want to give away two valence electrons in order to become stable."

Consider first the octet rule, which states that atoms combine or form ions with the goal of obtaining 8 electrons at their last level. In this way, an electronic configuration similar to that of the closest noble gas in the periodic table is reached. This happens because this configuration, of full electronic level, is very stable from the energy point of view

On the other hand, an ionic bond is a type of chemical bond that occurs when one atom gives up an electron to the other, in order for both to achieve electronic stability.

This union normally occurs between metal and nonmetal elements with different electronegativity, which means that the elements have different capacity to attract electrons. In general, metal elements are willing to donate an electron while nonmetals are willing to receive it.

In summary, an ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.

Finally,  the correct option is the second option: "An ionic bond is likely because they will want to give away two valence electrons in order to become stable."

Answer:

The answer would be 35.1

a) Liters ... It COULD be.  The "Liter" is a perfectly good unit of volume, but it's typically used for liquids and gases, not solids.

b) Grams ... definitely NOT.  The "gram" is a unit of mass, not volume.

c) Cubic centimeters ... Yes. This is a unit of volume.

d) All of the above ... No.

The kinetic energy is high because, the mass of the object is large and thus has a great momentum and its velocity low because it has a large mass.

We know that kinetic energy of an object K = 1/2mv² where m = mass of the object and v = velocity of the object and its momentum, p = mv

For a given value of kinetic energy, the mass of the object m = 2K/v². This implies that m ∝ 1/v².

So, as the mass of the object increases, its velocity decreases.

So. an object with large mass has low velocity while an object with small mass has high velocity.

Also, the kinetic energy, K = 1/2mv². So, K ∝ mv². So, if m is large and v is small, the product mv² is large and thus K = 1/2mv² is high.

So, the kinetic energy of heavy vehicles is high because, the mass of the object is large and thus has a great momentum and its velocity low because it has a large mass.

To develop technology responsibly, people must evaluate both the immediate and the long-term consequences of the technology.

This entails considering not only the short-term benefits and potential gains but also the potential risks, ethical implications, and broader societal impacts that the technology may introduce. Responsible development requires a comprehensive analysis of how the technology could affect individuals, communities, economies, and the environment. Striking a balance between innovation and accountability is essential to ensure that the benefits of technology are maximized while minimizing any unintended harm. By thoroughly examining both the immediate and long-term consequences, developers can make informed decisions that prioritize the well-being of all stakeholders and foster a more sustainable technological landscape.

In a chemical reaction the total mass of all the substances taking part in the reaction remains the same. Also, the number of atoms in a reaction remains the same. Mass cannot be created or destroyed in a chemical reaction.

Answer:

The upstroke is a mechanism that helps to raise the plunger and downstroke helps to help lower the plunger. On the up-stroke of the plunger, the lower valve opens and the upper valve is closed. Whereas, on the downstroke, the lower valve closes and the upper one opens.

For the coin that is flipped straight up we have:

a. The velocity at the top of its trajectory (at the maximum height) is 0.

b. When it reaches a high point of 0.25 m above where it was released, the initial velocity is 2.21 m/s.

c. The time that the coin spends on the air is 0.44 s.

a. The velocity of the coin at the top of its trajectory is zero because in the maximum height the ball will stop and then will start to move down.

b. When the coin reaches a high point of 0.25 m above where it was released, the initial velocity can be calculated as follows:

[tex] v_{f}^{2} = v_{0}^{2} - 2gh [/tex]

Where:

[tex] v_{f}[/tex]: is the final velocity = 0 (at the maximum height)

[tex] v_{0}[/tex]: is the initial velocity =?

g: is the acceleration due to gravity = 9.81 m/s² (it is negative because its direction is the opposite to the direction of motion of the coin)

h: is the height = 0.25 m

Hence, the initial velocity of the coin is:

[tex] v_{0} = \sqrt{2gh} = \sqrt{2*9.81 m/s^{2}*0.25 m} = 2.21 m/s [/tex]

c. The time that the coin spends on the air is given by the sum of the rise time and the fall time:

Rise time

[tex] t_{s} = -\frac{v_{f} - v_{0}}{g} = -\frac{0 - 2.21 m/s}{9.81 m/s^{2}} = 0.22 s [/tex]

Since the ball is caught at the same height as it was released, the rise time is the same as the fall time, so the total time is:

[tex] t = 0.22 s*2 = 0.44 s [/tex]  

Therefore, the coin spend 0.44 seconds in the air.

Divide the value of time by a thousand

From the Periodic Table...

Francium is a group 1 Element and Barium is a Group 2 Element

This statement is a giveaway as it already tells you that Barium has more valence electrons than Francium since it has 2 electrons in its Outer shell.

This Eliminates Options A and B

Francium has more electrons than Barium

So It should be at a higher energy level.

The correct statement is Francium has fewer valence electrons, but they are in a higher energy level.

The energy level of an element is the region of space around the nucleus where its electrons are found. This corresponds to the period of the element in the periodic table.

Thus, we can conclude that, Francium has fewer valence electrons, but they are in a higher energy level.
