What does that mean about the densities of the phases of water?
The solid state is the most dense, followed by the liquid state, then the gas state.
The solid state is more dense than the liquid state.
The liquid state is more dense than the solid state.
The gas state is the most dense, followed by the liquid state, then the solid state
The correct option is 2. The solid state is more dense than the liquid state.
The solid form of most substances is denser than the liquid phase so a block of most solids will sink in the liquid but a block of ice floats in liquid water because ice is less dense. Upon freezing the density of water decreases by about 9%. This is due to cooling of intermolecular vibrations allowing the molecules to form steady hydrogen bonds and locking into positions of hexagonal packing upon freezing to ice. These bonds are shorter in the crystal than in the liquid.

Which equation can be used to calculate the normal force on an object if you know the speed of the object, the coefficient of kinetic friction, and the force of kinetic friction on the object?
Answer:
D
Explanation:
The friction force is the weight force times the coefficient of friction. So diving by the coefficient gives you the weight force which is equivalent to the normal force.
The equation that we can used to determine the frictional force using the coefficient of kinetic friction and the normal force is given by the expression : F = u N.
Where N is the normal force by the weight of the body.
What is frictional force?Frictional force is a type of force acting on a body to prevents its motion. Hence, the frictional force is always negative. Frictional force acting on an object is making a resistance to the motion of the object.
There are both kinetic frictional force and static frictional force. The coefficient of frictional force is the ratio of the frictional force to the normal force on the object. The normal force on the object is equal to m g that is the force by its own weight.
If u is the coefficient of kinetic friction and N be the normal force acting on the object, then the force of kinetic frictional force F is given by,
F = u N.
Where N = mg.

The statement that best describes Keisha errors is an object in either state of equilibrium must have no net force acting on it.
What is an object at dynamic equilibrium?An object is said to be on a dynamic equilibrium when it moves at a constant speed, and all the forces on the object are balanced.
An object is also said to be on static equilibrium when it is unable to move because all the forces which act on it compensate for one another.

In other words, this effect is the change in the perceived frequency of any wave motion when the sender and receiver, or observer, move relative to each other.
In summary, there is always a change in the frequency of sound as the source of the sound moves towards or away from the observer. So, the Doppler Effect is an alteration of the observed frequency of a sound due to the movement of the source or the observer, that is, they are changes in the frequency and wavelength of a wave due to the relative movement between the wave source and the observer.

What is the volume of the cone?
Answer:
42.417 cm³
Explanation:
The formula to find the volume of a cone is :
V = [tex]\frac{1}{3}[/tex] × π r² h
Here,
r ⇒ radius ⇒ 3 cm
h ⇒ height ⇒ 4.5 cm
Let us find it now.
V = [tex]\frac{1}{3}[/tex] × π r² h
V = [tex]\frac{1}{3}[/tex] × π × 3 × 3 × 4.5
V = [tex]\frac{1}{3}[/tex] × π × 9 × 4.5
V = [tex]\frac{1}{3}[/tex] × π × 9 × 4.5
V = [tex]\frac{1}{3}[/tex] × π × 40.5
V = [tex]\frac{1}{3}[/tex] × 3.142 × 40.5
V = [tex]\frac{1}{3}[/tex] × 127.251

motion of its particles?
OA. They move more slowly and become fixed in position.
O B. They move more quickly and begin to move past one another.
C. They move at the same speed and in the same direction.
D. They move at the same speed but in random directions?
When a substance changes from a liquid to a solid, they move more slowly and become fixed in position. Option A is correct.
When a substance changes from a liquid to a solid, its particles lose energy and move more slowly. As the temperature decreases, the particles lose kinetic energy and start to arrange themselves into a fixed, ordered pattern. This causes the substance to solidify and the particles become fixed in position.
The transition from a liquid to a solid state is called freezing or solidification. During this process, the particles lose energy and their motion becomes more restricted, causing them to move more slowly and eventually become fixed in position. Option A is correct.
