The decibel level of noise from a jet aircraft is 130 dB when measured 30.0 m from the aircraft. How much sound power does the jet aircraft emit? How much sound power would strike the 5.0 x 10^-5 m^2 eardrum of a worker 10.0 m from the jet plane?

the pKa value of HAsO42- is 11.6. Is this value consistent with paulings rules

Figure 23-33 shows a zero-resistance rod sliding to the right on two zero-resistance rails separated by the distance L = 0.47 m. The rails are connected by a 11.7 resistor, and the entire system is in a uniform magnetic field with a magnitude of 0.750 T. a) Find the force that must be exerted on...

Two replicas of the same signal impinge on an antenna. The power flux density of each is 1 microwatt per square meter. The difference in path length for the two signals is 20 meters. The frequency is 1GHz. Calculate the combined power flux density of the sum of the signals.
