This would be louder sound. Higher pitch would be represented by a more compressed wave that oscillates more times over a shorter period. Higher amplitude represents higher sound because the wave oscillates at the same speed, yet higher.
Hope this helped, and have a nice day!

Answer:
the gas does no work.
Explanation:
An isochoric process is a process in which the volume of a gas is kept constant.
The work done by a gas during a transformation is given by:

where
p is the gas pressure
is the change in volume of the gas
For an isochoric process, the volume of the gas does not change, so

and so, according to the previous equation, the work done by the gas is zero:
W = 0
The collision between a photon or a bundle of energy and an electron is known as the Compton Effect in which there is a transference of energy and momentum by the photon to the recoiling electron. It must be noted that both energy and momentum are being conserved during this elastic collision. After such phenomena, the photon acquires energy (represented by hf/) and the electron also has acquired a kinetic energy (represented by K).
The change in pitch of a train's horn as it passes while you are
standing still can be described by the Doppler effect, but that
doesn't explain it.
