Answer:

Scientific models are used to explain phenomena that can not be experience directly and it is also used for prediction.

Explanation:

An example of idea model is the Eistein equation.  An idea model shows how things interact together to produce a particular result.

An example of physical model is the solar system.

Computer model is used to predict long term events and an example of this is computer simulations.

For each pair; which has higher kinetic energy?
RideAnS [48]

Explanation:

Kinetic energy is defined as the energy obtained by an object due to its motion. Whereas energy obtained by an object due to its position is known as potential energy.

(a)   When a sled is resting at the top of a hill then it means the sled in not moving. Hence, then it has only potential energy. But when a sled sliding down the hill  then it is moving from its initial position.

Hence, when a sled is sliding down the hill then it has higher kinetic energy.

(b)    When water is above the dam then it only has potential energy but when the water falls over the dam then it has higher kinetic energy.

Hey there!

Label A: Sublimation
Label B: Condensation
Label C: Melting

Remember sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state. Condensation is the conversion of a vapor or gas to a liquid. Melting is becoming liquefied by heat.

Hope this helps!
