Determine the intensity meter error when measuring the intensity of a sound wave having a frequency of 2 kHz in air with a sonic velocity of 344 m/s (1129 fps). The spacer thickness is 12 mm (0.472 in). The measured overall sound pressure level around an electric motor (including background noise) is 73.6 dB. The measured background sound pressure level is 71.1 dB. Determine the sound pressure level for the electric motor alone (background noise removed).

A wire of length L1=30cm has a fixed end and the other end is welded to another wire, whose linear mass density is 4 times smaller. The second wire passes over a pulley and a mass of 10kg is suspended from its other end.The distance L2 between the welding point and the pulley is 80 cm. A standing wave is produced in the composite wire, whose ends on the left wall and on the pulley remain fixed.If the frequency is as low as possible and there is a node at the weld spot, what is the number of nodes in this standing wave, including nodes on the left wall and on the pulley?a)3b)4c)5d)6e)7f)8g)9h)10i)11j)12k)13l)14m)15

The bore of each cylinder in a four-cylinder four-stroke internal combustion engine is 38 mm and the stroke of each piston is 165 mm. During testing, the engine runs at 180 revolutions per minute (rpm) with a pressure-volume indicator diagram showing a mean net area of 3.4 cm2 and a diagram length of 1.2 cm. The pressure scale on the indictor diagram is set to 150 kN/m2 per cm. Calculate the mean effective pressure (m.e.p) and the indicated power developed by this four-cylinder four-stroke engine.
