Energy is never created and energy never is destroyed
krok68 [10]3 years ago
5 0

Explanation:

The process in which energy gets transferred from one form of energy to another is called energy transformations. This process also defines the law of conservation of energy.          

"Energy is neither be created nor be destroyed" is explained by the law of conservation of energy. It only changes one form of energy to another.

There are many forms of energy i.e. electrical energy, mechanical energy, electromagnetic energy, sound energy etc.

The example of energy transformation is best explained by a roller coaster. At the top of a big hill, there exists only kinetic energy. As it descent the hill, the kinetic energy is converted to gravitational potential energy.

Hence, the correct options are (c) Energy is never created. and (e) Energy is never destroyed.

pysical property is defined as a blank that can be observed blank changing the matter into another type of blank
Molodets [167]

Physical property is defined as a property that can be observed without changing the matter into another type of matter.

<h3>What are physical properties of matter?</h3>

Physical properties of matter are those properties which can be easily observed without a change in the composition of the substance,

Some physical properties of matter include:

  • Volume
  • Shape
  • Density
  • Taste
  • Color
  • Mass
  • Electrical conductivity

In conclusion, physical properties do not change the composition of matter and can easily be observed.

Describe and give an example of the doppler effect
Alexxandr [17]
The Doppler effect is when the frequency of a sound changes as the position of you and the sound changes. For example, if a fire truck comes at you, the siren sound will increase, then, after it passes you, then the sound will decrease. The thing that just happened is the Doppler effect!

Have a nice day! :)
