A frequency generator (a device that produces sinusoidal signals whose frequency and amplitude can be independently set) is used to power a horn. The frequency is set to 2000Hz, and for a particular amplitude the sound intensity is measured to be 0.050 W/m2 at a distance of 12m.

What is the power output of the horn?

What is the intensity of the sound wave 2m from the horn?

Taking the speed of sound in air to be 334m/s, what is the wavelength of this sound?

Which types of electromagnetic waves have higher frequencies than the waves that make up ultraviolet light? check all that apply. radio waves infrared light microwaves gamma rays visible light x-rays

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
