Who are the main figures in Utilitarianism?

An act-utilitarian will only consider the immediate consequences of their actions.

A rule-utilitarian will never think critically, but only follow the rules.

Which of the following is a downside of Social Contract Theory?

A 3.00-m long gas column that is open at one end and closed at the other end has a fundamental resonant frequency 80.0 Hz. What is the speed of sound in this gas?

The tension in each of two strings is adjusted so that both vibrate at exactly 920 Hz. The tension in one of the strings is then increased slightly. As a result, six beats per second are heard when both strings vibrate. What is the new frequency of the string that was tightened?

A sound source emits 16.0 W of acoustical power spread equally in all directions. The threshold of hearing is 1.0 × 10-12 W/m2. What is the sound intensity level 30.0 m from the source?

A 5-m wire with a mass of 30 g, is under tension. A transverse wave, for which the frequency is 380 Hz, the wavelength is 0.9 m, and the amplitude is 8.4 mm, is propagating on the wire. The time for a crest of this wave to travel the length of the wire is closest to

A sound source emits 37.0 W of acoustical power spread equally in all directions. The threshold of hearing is 1.0 × 10-12 W/m2. What is the sound intensity level 30.0 m from the source?

A 2.60-m long gas column that is open at one end and closed at the other end has a fundamental resonant frequency 80.0 Hz. What is the speed of sound in this gas?
