Answer:

As the phase changes occur, the freedom of motion of the particles increases

Explanation:

In thermodynamics the state of matter: solid, liquid and gaseous.

We can characterize them, the solid state maintains a certain shape, which is why particles are tightly bound and can hardly move from their equilibrium positions.

The liquid state does not hold its shape, so the particles have more energy and can move a lot from their equilibrium position.

The gaseous state does not maintain the shape or the volume, so the interaction between the particles is very small, so they can move almost freely.

When examining the answer, the correct one is: As the phase changes occur, the freedom of motion of the particles increases.

a projectile is shot horizontally from the edge of a cliff, 230m above the ground. the projectile lands 300m from base of the cl
bekas [8.4K]

Answer:

The time taken by the projectile to hit the ground is 6.85 sec.

Explanation:

Given that,

Vertical height of cliff = 230 m

Distance = 300 m

Suppose, determine the time taken by the projectile to hit the ground.

We need to calculate the time

Using second equation of motion

s=ut+\dfrac{1}{2}gt^2

Where, s = vertical height of cliff

u = initial vertical velocity

g = acceleration due to gravity

Put the value in the equation

230=0+\dfrac{1}{2}\times9.8\times t^2

t=\sqrt{\dfrac{230\times2}{9.8}}

t=6.85 sec

Hence, The time taken by the projectile to hit the ground is 6.85 sec.
