Explain what it means when we say a substance is magnetic
MariettaO [177]
A magnetic field is a force field, invisibly pushing electrically charged objects just as a gravitational field pulls objects with mass. Whereas all objects with mass exert a gravitational field, however, not all objects have a magnetic field. Magnetic fields are created by electrical charges. Thanks to their structure at the atomic level, some substances -- like the iron in magnets -- have a permanent magnetic field.

When a guitar is tuned to adjust it pitch what is it that is changed?
suter [353]

Answer:

B) Its frequency

Explanation:

  • <u>The pitch of sound heard depends on its frequency of the sound wave. Frequency refers to how fast the sound wave is oscillating. </u>
  • A high frequency sound wave has a high pitch while a low frequency sound wave has a low pitch.
  • The faster the sound wave oscillates the higher the pitch. For instance, a guitar with a big heavy string will vibrate slowly and thus create a low pitch.

s2008m [1.1K]

Answer:

Wc = 7.84    weight of crown
