Answer:
Thermal expansion occurs when an object expands and becomes larger due to a change in that specific object's temperature. Temperature is the average kinetic (basically movement) energy of the molecules in a substance. A higher temperature means that the molecules are moving faster on average.
Answer:
Electronmagnetic waves: yes
Mechanical waves: no
Explanation:
Electromagnetic waves consist of electric fields and magnetic fields that oscillate perpendicularly to each other, and also in a plane perpendicular to the direction of propagation of the wave (therefore they are called "transverse waves".
As all waves, electromagnetic waves transport energy (but not matter). In particular, the type of energy transferred by electromagnetic waves is in the form of radiation, also called light energy.
Conversely, mechanical waves consist of oscillations of the particles in a medium. Mechanical waves also carries energy (but not matter), but not in the form of radiation (light energy): in fact, the energy is carried as vibrations of the particles in the medium, so it is a different type of energy.
Answer:
The Richter Scale is used to define the power of earthquakes, it was created by Charles Ritcher in the 1930s to work as a seismogram, regulated and assessed by a seismometer, which responds to ground motions at a distance of around 62 miles from the event, and records the seismograph, a <em>base 10</em> logarithmic scale.
Thereby the most suitable options are <em>A)</em><em>, </em><em>B)</em><em> </em>&<em> </em><em>D)</em><em>.</em>
Answer:
directly
Explanation:
In linear circuits, voltage and current are directly related. In nonlinear circuits, the relationship depends on the nonlinearity. We generally study linear circuits.
