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...
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...
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...

Using that picture above and this data... A block of mass M slides down a plane at an angle of 37o to the horizontal. The coefficient of kinetic friction = 0.20. The horizontal lines in the picture represent magnitude of forces...
