Answer:<u><em> (Light and sound both require a medium in which to travel)</em></u>
Explanation: <em>Sound and light always have the means to travel and get somewhere as fast as possible. Light is always faster than sound but it does not matter because they both almost always get where they want.</em>

<em>Part 2. light was composed of particles or waves, a wave-particle dual nature soon was found to be characteristic of electrons as well. The evidence for the description of light as waves was well established at the turn of the century when the photoelectric effect introduced firm evidence of a particle nature as well. basically when light hits a metal object . :)</em>

Explanation:
The detailed step by step calculation using the vanderwaal's equation of state for ideal gases is as shown in the attachment.
Answer:
a) The work done by a nonconservative force depends on the path taken. True.
c) A potential energy function can be specified for a conservative force. True
d) A conservative force permits a two-way conversion between kinetic and potential energies. True
Explanation:
Non-conservative forces dissipate. For example, friction or air resistance or drag.
A conservative force's property is that the work done in moving a particle does not depend on the path it has taken. For example, stored energy or potential energy. It permits two-way conversion between kinetic energy and potential energy. For example if a car goes up a hill, it converted kinetic energy in to potential energy. and if the car goes down the hill without hitting the gas pedal, it will roll down converting the potential energy in to kinetic energy.
b) A nonconservative force permits a two-way conversion between kinetic and potential energies. False
e) A potential energy function can be specified for a nonconservative force. False
f) The work done by a conservative force depends on the path taken. False
Electricity is not apart of it
