Sublimation is the state shown in the model

<h2>Hello!</h2>

The answer is: Sublimation.

<h2>Why?</h2>

From the model, we have that the phase transition type is sublimation since there is a substance in the solid phase changed to the gas phase.

Sublimation is the process where a substance changes its phase (state) from solid to gas phase without passing through the liquid phase.

When the molecules of a substance are joined, meaning that the space between them is minimum, it's called a solid phase.  

When the molecules of a substance are separated, even more than they are in the liquid phase, there is a new phase called the gas phase.

Have a nice day!

They can share electrons. By sharing, they form a covalent Bond and that way atoms can be stable.

A bullet glider and a target glider both have a mass of 0.200 kg. The bullet glider is moving 0.450 m/s
Romashka [77]

Answer:

the two gliders collide, the mobile glider will transfer a bit of time to the fixed glider, which is why it comes out with a speed that is smaller than that of the bullet glider.

Explanation:

When the two gliders collide, the mobile glider will transfer a bit of time to the fixed glider, which is why it comes out with a speed that is smaller than that of the bullet glider.

Changes can occur that the gliders unite and move with a cosecant speed less than the initial one.

The whole process must be analyzed using conservation of the moment.

             p₀ = m v₀

celestines que clash case

             p_f = (m + M) v

             po = pf

             m v₀ = (n + M) v

             v = \frac{m}{m+M}

calculemos

            v= \frac{0.200}{0.200+M} 0.450

            v= 0.09 m/s

elastic shock case

           p₀ = m v₀

           p_f = m v₁ +M v₂

           p₀ = p_f

           m v₀ = m v₁ + m v₂

Anna drives north at a speed of 50 km/h for the first hour. Then, she drives north for a second hour but slows down to 30 km/h.
8090 [49]

Answer:

The correct answer is A The distance is greater in the first hour because her speed is faster.

Explanation:

During the first hour, Anna is driving at a speed of 50 km/h. During the second hour, she is only driving at a speed of 30 km/h. The faster she goes, the farther she will go.

Hope this helps,
