A bus traveled 280 kilometers between two cities . It left the first city at 3:00 p.m. and arrived at the second city at 7:00 p.m. What was the average speed of the bus during the trip ?

The earth's plates move, slide alongside one another, pull apart, or collide. Therefore, option (A) is correct.

What is it called when tectonic plates collide?

If two tectonic plates of the earth collide there is the formation of a convergent plate boundary. One of the converging plates will usually move beneath the other is called subduction.

The fluids are released from the rock as the sinking plate moves deeper into the mantle, causing the overspreading mantle to partially melt. The new magma rises and forms volcanoes.

When two plates are pulling apart from each other, it is a divergent plate boundary. The magma rises from deep within the Earth along these boundaries and forms a new crust on the lithosphere. Most divergent plate boundaries form submarine mountain ranges known as oceanic spreading ridges and are underwater.

Another type of plate boundary that occurs when tectonic plates slide alongside one another is known as a transform plate boundary. As the earth's plates rub each other, large stresses can cause the rock to break, resulting in earthquakes.

A pitcher throws a ball toward a player holding a softballbat. The player uses the bat to hit the ball. The bat applies a 10-newton force to the ball. The statement correctly describes the reaction force between the bat and ball is the reaction force is the force applied to the bat by the player holding the bat. Therefore, option B is correct.

What do you mean by the force ?

The term force is defined as the push or pull on an object with mass causes it to change its velocity. Force is an external agent capable of changing a body's state of rest or motion. Force has a magnitude and a direction.

A force is a physicalquantity which cause a motion in an object at rest or changes to change the.The direction of motion of a moving object or the shape or size of the object.

The pitcher threw the ball but that isn't the reaction between the ball and the bat, the bat job is hit the ball.The statement correctly describes the reaction force between the bat and ball is the reaction force is the force applied to the bat by the player holding the bat.

Thus, option B is correct.

Your question is incomplete, most probably your question was as follows:

A pitcher throws a ball toward a player holding a softball bat. The player uses the bat to hit the ball. The bat applies a 10-newton force to the ball.

Which statement correctly describes the reaction force between the bat and ball?

A. the reaction force is that force which causes the ball to move towards bat.

B. the reaction force between the bat and ball is the reaction force is the force applied to the bat by the player holding the bat.

C. the reaction force is that force which pull ball towards the ground.

Answer:

B) the reaction force is the force applied to the bat by the player holding the bat

Explanation:

the pitcher threw the ball but that isn't the reaction between the ball and the bat, the bat job is to hit the ball

Final answer:

Selenium tetrafluoride (SeF4) is a molecule characterized by a covalent bond, not an ionic bond. This bond is formed by the sharing of electron pairs between selenium and fluorine atoms.

Explanation:

The question we have here asks, Is selenium tetrafluoride an ionic or covalent bond?

Selenium tetrafluoride, otherwise known as SeF4, is a molecule formed by the chemical bonding of selenium and fluorine. This bonding is not ionic in nature, but covalent. When you hear the term covalent bond, it refers to a bond formed by the sharing of electron pairs between atoms. Here, selenium and four fluorine atoms share their electrons, therefore creating a molecule of selenium tetrafluoride via a covalent bond.

Final answer:

Selenium tetrafluoride (SeF4) is a covalent bond because it involves the sharing of electrons between two nonmetals, selenium and fluorine. This contrasts ionic bonds, which typically involve a metal donating electrons to a nonmetal.

Explanation:

Selenium tetrafluoride, identified by the chemical formula SeF4, is a type of covalent bond. This classification is due to the fact that selenium and fluorine are both nonmetals. In chemistry, when two nonmetals form a compound, they usually share electrons, resulting in a covalent bond. The electrons are shared because each atom wants to achieve a stable setup, often attained with a full outer shell. Therefore, these compounds are described as covalent or molecular. An example of an ionic bond, on the other hand, involves a metal and a nonmetal. In this type of bond, the metal will lose electrons to become a positively charged cation, while the nonmetal will gain these same electrons to become a negatively charged anion.
