S1 and S2
Two coherent sources of sound, S1 and S2, produce sound waves of the same wavelength, λ = 1 m, in phase. S1 and S2 are placed 1.5 m apart (see fig). A listener, located at L, directly in front of S2 finds that the intensity is at a minimum when he is 2 m away from S2. The listener moves away from S1, keeping his distance from S2 fixed. The adjacent maximum of intensity is observed when the listener is at a distance d from S1. Then, d is

As Fig. shows, S1 and S2, are spring balances. Block A is hanging from spring balance S1 and immersed in liquid L which is contained in beaker B. The mass of beaker B is 1 kg and mass of liquid L is 1.5 kg. Balances S1 and S2 reads 2.5kg and 7.5kg, respectively. What will be the readings of S1 and S2 when block A is pulled up out of the liquid. Find the reading of S1 and `S_(2)?

Bainbridge’s mass spectrometer separates ion having the same velocity. The ions, after enteering through slits, S1 and S2, pass through a velocity selector composed of an electric field produced by the charged plates P and P’ and a magnetic field B perpendicular to electric field and the ion path.Thew ions that then pass undeviated through the crossed E 1 and B fields enter into a region where a second magnetic field B exists, where they are made to follow circular path. A photographic plate ( or a modern detector) registors their arrival. If r is the radius of the circular orbit , then specific charge qm of ion is
