Assume the speakers are reconnected so that the 440 Hz sounds they emit are accurately out of phase. At what positions (how far should the microphone be moved to the right) are the intensity maximum and minimum now.
An aircraft weighing 991 N is accelerated at 11 m/s2 for 13 seconds, at which time the aircraft launches. How much work was done on the aircraft
A 200 km long high-voltage transmission line 2 cm in diameter carries a steady current of 1050 A. If the conductor is copper with a free charge density of 8.8 x10^28 electrons per cubic meter, how various years does it take one electron to travel ..
A house has a floor area of 115 m2 and an outside wall that has an area of 24 m2. The earth's magnetic field here has a horizontal component of 2.50 e 10-5 T that points due north and a vertical component of 4.30 e 10-5 T that points straight down..
A magnetic field is perpendicular to the plane of a single-turn circular coil. The magnitude of the field is changing, What emf and current are induced in the square coil
