Maybe this can help.

In mechanics, speed increase is the pace of progress of the speed of an article regarding time (acceleration). Speed increases are vector amounts (in that they have greatness and direction). The direction of an item's speed increase is given by the direction of the net power following up on that article. The size of an item's speed increase, as depicted by Newton's Second Law, is the consolidated impact of two causes:

the net equilibrium of all outer powers acting onto that item — size is straightforwardly relative to this net coming about force;

that article's mass, contingent upon the materials out of which it is made — extent is conversely relative to the item's mass.

<u>There are two ways of thinking about it</u>:

  • First way: The definition of the acceleration states that an object accelerates when it <u>has a force applied to it</u>
  • Second way: The definition of the acceleration states that an object accelerates when it <u>changes its velocity</u>

<u></u>

<u><em>Reasons</em></u>

  • <u><em>For the first way</em></u><em>, by newton's second law, force equals to the product of mass times acceleration. The mass of the objects stays constant thus it is a constant in this equation. Thus when the Force isn't zero or bascially when it is applied, then the object must accelerate</em>
  • <u><em>For the second way</em></u><em>, acceleration is the rate of change of velocity, thus as velocity changes, the object must be accelerating</em>

Hope that helps!

What is the relationship between the internal energy of a substance and its particle movement?
ss7ja [257]

Answer: The closeness, arrangement and motion of the particles in a substance change when it changes state. Materials are a store of internal energy , due to the motion of particles and the chemical bonds between them. When a substance is heated, its internal energy increases: the movement of its particles increases.

How does the crystalline structure of a metal differ from the structure of an ionic compound, such as sodium chloride or cesium
Sergio [31]

Answer:

The metal cube lattice is made of only one kind of atom.

Explanation:

As we know that metallic crystals are made up of only one kind of element.  A metal crystal is actually a huge sea of positive charges embedded in the layers of negative charges (electrons). The whole crystal is made up of same kind of atoms, e.g crystals of gold, crystals of iron.

If we talk about structure of metallic crystal, it can be body centered cubic, simple cubic, hexagonal or close cubic packing.

Now, coming towards the ionic crystals, we know that they are basically the crystals of ionic compounds like sodium chloride or cesium chloride. These crystals are formed due to ionic bonding between two or more than two kinds of elements/atoms. It is not possible for an ionic crystal to be composed of only one kind of atom. As far as structure is concerned, they can have different structure based on bonding between atoms in an ionic compound, e.g NaCl has octahedral geometry.

Therefore, it is very evident that best option is A.
