That is true.
In the solid state the molecules of water have the lowest energy content.
To pass from solid state to liquid stated water needs to gain some energy to increase vibration and motion of the molecules and reach a higher energy states.
To pass from liquid state to vapor (gaseous state) the molecules of water have to gain more energy to increase more the motion of the molecules and reach a more energetic stated.
Then you can think that when the water vapor becomes liquid (droplets) it needs to release some energy.
The droplets formed on a glass of ice water is an example of water condensation, one of the processes of the water cycle.
The droplets on the external surface of a cold glass are the result of condensation of water.
Condensation is the pass from vapor state to liquid state. As whe have stated, when water passes from vapor state to liquid state it has to release energy because liquid state is lower in energy than vapor (the molecules in water experiment slower motion than molecules of vapor).
Answer:
The electromagnetic force
Explanation:
The electromagnetic force is one of the four fundamental forces of nature. Namely, they are:
- Electromagnetic force: it is the force exerted between electrically charged particles (and between magnetic fields). The force can be either attractive (if the two charges have opposite signs) or repulsive (if the two charges have same sign), and it acts over an infinite range.
- Gravitational force: it is the force exerted between objects with mass. It is always attractive, and it also has an infinite range of action. It is the weakest of the four fundamental forces.
- Strong nuclear force: it is the force that acts between protons and neutrons inside the nucleus, and it is responsible for keeping the nucleus together and preventing it from breaking apart (due to the electrostatic repulsion between protons)
- Weak nuclear force: it is the force responsible for certains nuclear decays, such as the beta decay, in which a neutron turns into a proton, emitting an electron and an antineutrino.
Answer:
b. a large elliptical galaxy
Explanation:
In elliptical galaxies the stars are grouped in an elliptical shape, it has a low quantity of gas and dust in comparison to spiral galaxies, and its stars belong to an old population, there is not new stellar formation in it.
The stars orbit in a messy way which made to believe that they form from the merger of galaxies.
They are also really massive (around 
solar masses).
The most massive and luminous can be found in the center of cluster of galaxies.
Answer:
Acceleration is the rate of change of velocity with time.Acceleration occurs anytime an object's speed increases or decreases, or it changes direction. Much like velocity, there are two kinds of acceleration: average and instantaneous. Average acceleration is determined over a "long" time interval.
Explanation:
good luck
Vê quantidade de movimento precisa ta em kg.m/s certo?
a questão disse que a gravidade é de 10 int posso dizer q minha massa é de 36kg pois p(360n)= massa . gravidade(10).
ja a velocidade esta km/h int vou dividir por 60 por 3,6 ou 600 por 36, aumentando de 10 vezes pra poder ajudar no calculo.
quantidade de movimento é Q= m(36) . velocidade( 600/36)
Q= 36.600/36 se corta 36 de cima com o 36 de baixo vai ficar 600kg . m/s
