When water is a gas following are its characteristics:

Like every other substance, water also exists in three forms on the basis of its physical state:

The properties of steam are similar to the properties of any gaseous substance. The particles in the gaseous state are farthest from each other than in any other state. The velocity of molecules is maximum in a gaseous state.

As the velocity of molecules is maximum, several collisions between the molecules take place every second and these collisions are perfectly elastic.

Like the Bullard balls on a pool table, gas particles are ubiquitous, so they are similar.

When two billiard balls collide the collision is nearly elastic. In an elastic collision the kinetic energy of the system is conserved before and after the collision. Therefore for simplicity, we can assume that the collision with the billiard ball is perfectly elastic. Momentum is conserved regardless of the type of impact. This means that the total momentum of all colliding objects before the collision is equal to the total momentum after the collision.

If you hit straight and the cue ball stops at impact the cue ball's momentum should all be eight This is because momentum is conserved Hitting diagonally keeps both balls moving after the collision. That is ball one exerts the same force on the ball two as ball two exerts on ball one This way momentum is conserved, so every time ball two gains momentum ball one loses This is Newton's third law.

Matter is the substance which have some mass and can occupy space is well.

Matter is any substance which has mass and occupy some space by having the volume. All physical things are made up of matter and an easily observed property of matter is its state or phase. There are three states of matter Solid, Liquid and Gas. These three matter are responsible for the production of things. The matter can occupy the space but the same matter can not occupy the same space.

The state of a substance directly depends on the balance between kinetic energy of the individual particles and the intermolecular forces between them. If forces are strong, state of matter changes into solid and liquid.

So we can conclude that matter is the substance which have some mass and can occupy space is well.

The racer which accelerates at 50.0 m/s2 for 5 seconds then brakes at 60.0 m/s2 to a complete stop has an acceleration of  2 m/s^2, travels a distance of  100m in 5 seconds.

What is acceleration  ?

Acceleration is the measure of a change in velocity. Acceleration frequently, but not always, denotes a shift in speed. The direction of motion is changing, therefore an object travelling at a constant speed along a circular path is still going ahead.

Given:

Acceleration, a=?

Time, t =  5 seconds

Final velocity, v= 60.0 m/s2

Initial velocity, u=  50.0 m/s2

Therefore putting the formula,

v = u + at

=> 60 = 50 +5.a

therefore, a = 2 m/s^2

Therefore distance can be found by the formula,

x = u + 1/2 at^2

Where x is the distance.

=> x = 50 + 2 . 5^2

x = 100m

To find out the coefficient of kinetic friction between the box and the floor we will the formula,

μ = F/N

where,

F is friction force

N is normal force

So by question given is mass and acceleration we have to calculate friction force,

So to find F we use,

F = ma

F = 10 x 0.75 m/2

F = 7.5 m/2

By using formula of coefficient of kinetic friction,

μ = F/N

μ = 7.5 / 75

μ = 0.1 m/2

The kinetic friction coefficient (F) is the ratio of the kinetic friction force (F) between both the surfaces in contact during motion to the normal force Ff/N. The static and kinetic coefficients of friction are both affected by the surfaces in contact. Their values are determined through experimentation.

According to the given statement the final speed is v = 25 m / s.

Velocity's rate of change with time, both in terms of speed and direction. A point or object going straight ahead is accelerated when it increases or decelerates. Even if the speed remains constant, motion on a circle increases because the direction is always shifting.

We utilise the relations and kinematics for this exercise.

The train accelerates in the first section from v0 = 7.0 m/s to 13 m/s in a time of t = 8.0 s.

v = v₀ + a t

a = [tex]\frac{v-v_o}{t}[/tex]

a = 13-7/8

a = 0.75 m / s²

Second part Accelerate again for t = 16 seconds

v = v₁ + a t

For this interval the initial velocity is v₁ = 13 m / s

v = 13 + 0.75  16

Explanation:

the wight of an object is determined by the pull of gravity on it

Red hot is not as hot as blue hot because as the temperature increases the frequencies of light emitted becomes higher leading to emission of smaller wavelength lights.

All objects emits light, even at room temperature. But it cannot be seen with human eyes as the wavelength is too high. When heated the wavelength starts to decrease ( reaching the visible spectrum ) as high heat produce high frequency lights.

The wavelength of colour visible to human eyes starting from highest wavelength to lowest wavelength is as follows: Red, Orange, Yellow, Green, Cyan, Blue and violet.

The bag would move in the direction of the applied force.

What is the direction?

Recall that work is done when the force applied moves a distance in the direction of the force. In this case, we can see that the force was applied from the right. Do not also forget that the force applied must make the object to move in a given direction. The direction in which the acceleration is imparted must also be in the direction of the force.

The understanding of the impact of force on motion could be seen from the Newtons law. We know from the Newton’s law that an object would remain at rest or in  a state of uniform motion unless it I acted upon by an external force. This external force makes the object to move in the direction of the force.

When energy moves through a medium (such as air, water, or any other liquid or solid matter), it creates a pattern of disruption that propagates away from the source of the sound.

Two identical loudspeakers separated by distance delta X each emit sound waves of wavelength lambda and amplitude A along the x-axis.

What is the minimum value of the ratio delta X/ wavelength for which the amplitude of their superposition is also A?

On a location along the X axis, we receive a portion of the difference in their attacks when we talk along the X axis. The attacks over the wavelength are equal to the phase difference, or delta. Lambda divided by pi. The square of the temperature tude of the first three waves plus the square of the second wave's temperature, B plus two times even a two times course delta, is what determines the amplitude following a superimposed wave. Okay. The resultant amplitude, A, equals the square root of a squared plus a squared plus two times a squared in this situation because the amplitude is tiny.

Delta is now, of course, square on both sides. And we discover that A squared equals two A squared plus cost. This widget's delta are is equivalent to -1/2. Delta will be seven Pi over six.
