The pitch of a sound is decreased, when a sound source approaches the observer.
Explanation:
Pitch is nothing but it is a property that helps to determine whether the sound is high or low. Doppler effect helps to understand this concept easily. The pitch of the sound is mainly calculated based on the frequency of the sound wave arose from the sound source.
As the wellspring of sound waves moves toward an audience, the sound waves draw nearer together, expanding their recurrence and the pitch of the sound.

The sentence can be completed as follows:
"Electricity is the movement of charges from one atom to another along a conductor."
The movement of the the charges is due to the presence of a potential difference across the conductor, which pushes the charges. More specifically, in normal conductors, the carriers of electricity are the electrons. Therefore we can rewrite the sentence as
"Electricity is the movement of electrons from one atom to another along a conductor."
Final answer:
Electricity is the flow of electrons from one atom to another along a conductor such as a metal wire. This motion is driven by a potential difference or voltage. While the overall speed of electron movement is slow, the propagation of the electrical effect (current) is near light speed.
Explanation:
Electricity is the movement ofelectrons from one atom to another along a conductor. These carriers of electric charge move due to potential difference, also known as voltage. For example, in a metal wire, free electrons move from the negative (low potential) end towards the positive (high potential) end of the wire, creating a flow of electricity.
An interesting detail is that while the electrons move quite slowly overall, the electric effect they produce, the electric current, propagates almost at the speed of light.
The conductor is a material that allows this movement of electrons to occur efficiently, metals like copper or silver are typical conductors.
