A point source emits 30.0 W of sound isotropically (in all directions). A small microphone with an area of 0.750 cm2 is located 200 m away from the source. (a) Find the sound intensity at the location of the microphone in W/m2 . (b) Find the power intercepted by the microphone. (c) Find the displacement amplitude sm of the sound wave at the position of the microphone taking the frequency of the sound to be 50.0 Hz.

i have some physics questions. hopefully you can answer these
all please.
A block with mass m = 2.0-kg attached to the end of a
spring undergoes simple harmonic motion on a horizontal
frictionless surface. The oscillation period is T = 5.5-s
and the oscillation amplitude is A = 13.8-cm. When the
spring is unstretched the block sits at a distance L =
2.2-m from a wall. Suppose we snap the spring at the very moment
the block passes through...

For the questions on this page, assume that that an induction motor is rated to deliver 10kW (approximately 13.3HP} when operated at 240VRMS 60Hz. The motor has a lagging power factor of 0.8. The building electrical service only supplies 208VRMs, so the motor can not be connected directly to the electric service. An ideal transformer is used to create...

Alternative energy sources that are renewable and that can reduce greenhouse gas emissions are actively being developed. In this example, you wish to explore the feasibility of two alternative energy sources to petroleum. The U.S. petroleum consumption is approximately 3 million m per day. You may assume that the fuel value of petroleum can be represented by octane. The density of octane is 0.70...
