<em>Pitch </em><em />is defined as the sensation of a frequency. A high frequency corresponds to a high pitch. Low frequency corresponds to low pitch. So it is right to assume that rising frequency will cause a rising pitch.
<em>Amplitude </em> is defined by the loudness of sound. It is the size of a vibration. The bigger the vibration is, the louder the sound it will produce. So it is safe to say that rising amplitude will result in rising volume. <em>Wavelength</em><em> </em>is the distance between the trough of one wave and the trough of the next wave; or the crest of one wave and the crest of the next wave. Short wavelengths mean more waves pass through a certain point at a certain time. As a result, shorter waves create higher frequencies. Longer waves, on the other hand, create lower frequencies. And using the definition of pitch above, we can then say that longer wavelengths will result in declining pitch.
in physics, resonance is a phenomenon in which a vibrating system or external force drives another system to oscillate with greater amplitude at specific frequencies. example a familiar example is a playground swing, which acts as a pendulum.
A contact force is defined as a force which requires some contact to occur. When we apply force that is in contact with the objects are called as contact forces.
In the context, Carmen is loading furniture and boxes on a moving van by picking up by picking up the boxes or furniture on a cart and pushing it onto the van. Carmen uses contact forces to lift the boxes and furniture onto the van.
