Answer:
All change in their form in relation to amount of heat energy.
Explanation:
- Due to the chemicals bonds that are within these forms of matter. The solids are compact and have strong bonds where the atomic molecules are attached to each other firmly.
- While in gases the bonds are least developed and molecules are able to move freely with the least friction. In water, the bonding is neither compact nor loose.
- All this is possible due to the addition of heat to molecules as they gain energy they start to move. Hence changes their forms, while the water molecules one hydrogen bond that is attached to nonbonding pairs of electrons. The water molecules form and reform continuously.
Answer:
D. 1.33 segundos.
Explanation:
El cuerpo es experimenta un movimiento en caída libre al modificarse su velocidad por efecto de la gravitación terrestre. Este cuerpo alcanza instantáneamente el reposo cuando se encuentra a su altura máxima, el tiempo puede obtenerse sabiendo la aceleración y las velocidades incial y final a partir de la siguiente ecuación cinemática:
Donde:
- Velocidad final del cuerpo, medida en metros por segundo.
- Velocidad inicial del cuerpo, medida en metros por segundo.
- Aceleración gravitacional, medida en metros por segundo al cuadrado.
- Tiempo, medido en segundos.
Ahora se despeja el tiempo:
Si 
, 
y 
, entonces:
Por ende, la respuesta correcta es D.

Answer the point I wish you would have the greatest potential energy is when you are coming down the swing and getting ready to go up the greatest kinetic energy is whenever you’re falling back down from the height of how far you went up
