Find the lowest frequency for which destructive interference
Two loudspeakers, A and B, are driven by the same amplifier and emit sinusoidal waves in phase. Speaker B is 2.00 m to the right of speaker A. Consider point Q along the extension of the line connecting the speakers, 1.00 m to the right of speaker B. Both speakers emit sound waves that travel directly from the speaker to point Q. a) What is the lowest frequency for which constructive interference occurs at point Q? b) What is the lowest frequency for which destructive interference occurs at point Q?
Net force acting on particle of mass 2 kg is 10N in north direction.At t=o, particle was moving eastwards with 10m/s. Find displacement and velocity of particle after 2 seconds.
if two metal spheres are mounted on insulators then how will we give them equal charge by using a charged glass rod?
How long does it take for reach that speed
How to set out a scientific report and include a collection and analysis of data to support my claims/findings. I am making a model and videoing it, i am wondering how to do a scie

two insulated charged copper spheres A and B of identical size have charge q and -3q respectably .when they are brought in contact with each other and then separated,what are the n
Methods of Demagnetization: 1. A magnet loss it's magnetic properly when it is heated strongly. 2. Practically a magnet can be demagnetized by hammering when it is placed in
