The internal energy of a system....

Physics
1 answer:
Angelina_Jolie [31]3 years ago
5 0

Answer:

C. Equals the sum of all forms of energy contained within the system.

D. Equals the heat entering the system at constant volume.

E. Equals the heat entering the system plus the work done on the system

Explanation:

Internal energy is defined as the sum of internal kinetic energy and internal potential energy, that is, the energy contained within the system.

The first law of thermodynamics relates the change in the internal energy with the heat entering the system (Q) and work done on the system (W), with the following expression:

\Delta U=Q+W

If the system is at constant volume the work done is zero. Therefore, the heat entering the system increases its internal energy:

\Delta U=Q

Two speakers emit the same sound wave, identical frequency, wavelength, and amplitude. What other quantity would be necessary to
Komok [63]

Answer:

Phase Difference

Explanation:

When the sound waves have same wavelength, frequency and amplitude we just need the phase difference between them at a particular location to determine whether the waves are in constructive interference or destructive interference.

Interference is a phenomenon in which there is superposition of two coherent waves at a particular location in the medium of propagation.

When the waves are in constructive interference then we get a resultant wave of maximum amplitude and vice-versa in case of destructive interference.

  • For constructive interference the waves must have either no phase difference or a phase difference of nλ, where n is any natural number.
  • For destructive interference the waves must have a phase difference of n×0.5λ, where n is any odd number.
