The second one is best. Gravity is an attractive force that acts between all objects, whether they're in contact or not.
Answer:
Explanation:
The energy, E, from a capacitor, with capacitance, C, and voltage V is:
If we increase the Voltage, the Energy increase also:
The voltage difference:
<span>A
sound wave is a pressure wave that results from the vibration of the particles
o the medium from the source. The motion of the particles in the medium is
parallel to the direction of the energy transport. The type of wave formed by a
sound wave is the longitudinal wave. </span>A longitudinal wave is
characterized by rarefactions. A longitudinal wave is a wave motion wherein the
particles in the wave medium are displaced parallel to transport. When motion
is detected from the source, the particle next to it vibrates from its rest
position and a progressive change in phase vibration is observed at each
particle within that wave. The result is that the energy is transported from
one region to the other. These combined motions result in the movement of
alternating regions of rarefaction in the direction of propagation.
