    Calculate Ambient Noise Intensity Increase: 86.0 dB - 85 dB

    A machinist is in an environment where the ambient sound level is of 85 dB, i.e., corresponding to the 8 Hours/day noise level. The machinist likes to listen to music, and plays a Boom Box at an average level of 86.0 dB. A.Calculate the INCREASE in the sound level from the ambient work...

    Period of Oscillation for a Standing Transverse Wave on a Flexible String

    A snapshot of a standing transverse wave on a flexible string is taken when the displacement is at a maximum showing two trough's and two peaks(1.5 waves). The string is 1.52 m long with tension 4.00 N. The total mass of the string is 10.81 g. Find the period of the oscillation. I found the...

    Calculating Forces and Magnitude for a 2.50 kg Block on a Frictionless Table

    A block of mass 2.50 kg is pushed 2.18 m along a frictionless horizontal table by a constant 17.0 N force directed 22.6o below the horizontal. Determine the magnitude of the normal force exerted by the table. and Determine the net force on the block. I already found that the work done...
