1. If ice is melting, energy is applied. We need energy whenever we need to change the state either from solid to liquid or from liquid to gas. The energy is used to break the molecular force between the water molecules of the ice so that they can be farther apart and become liquid state.

2. And at atomic level, the atoms are speeding up. Part of the energy is used to increase the kinetic energy of the ice particles, since the faster the particles are, the hotter an object will be. Therefore, since melting requires the ice to become a hotter substance, the particles are obviously moving faster.

Which respiratory-associated muscles would contract or relax during forced expiration, for example blowing up a balloon?
Nutka1998 [239]
The correct answer is B, internal intercostal muscles and abdominal muscles would contract.
Exhalation is the flow of the breath out of the body. During forced exhalation, internal intercostal muscles contracts which lower the rib cage and decrease thoracic volume, while the abdominal muscles push up on the diaphragm which causes the thoracic cavity to contract.

Vera_Pavlovna [14]
An hypothesis is a possible explanation for a set of observations or answer to a scientific question. A supposition or proposed explanation made on the   
basis of limited evidence as a starting point for further  
 investigation. 
 And practically, an hypothesis is used as the basis for further experiments, where the hypothesis is rigorously tested under varying conditions. The hypothesis that is tested and modified under different conditions may become a general 
 theory
 .The hypothesis that has the least number of variables sufficient to explain the phenomenon is preferred.

Select the correct answer. which sentence describes an object that has kinetic energy? a. a seagull sits on top of a fence post.
ololo11 [35]

" a boat sails across the ocean" possess Kinetic energy. hence option d is correct.

<h3>What is Kinetic energy?</h3>
  • Chemical energy, thermal energy, electromagnetic radiation, gravitational energy, electric energy, elastic energy, nuclear energy, and rest energy are only a few of the many different types of energy that exist. Potential energy and kinetic energy are the two basic categories that can be used to group them.
  • An object's kinetic energy is what drives its motion. Kinetic energy can be converted into other types of energy and transported between objects.
  • The energy an object has as a result of motion is known as kinetic energy in physics. It is described as the effort required to move a mass-determined body from rest to the indicated velocity. The body holds onto the kinetic energy it acquired during its acceleration until its speed changes.
