A source S emitting sound of frequency `300Hz` is fixed on block A which is attached to the free end of a spring `S_(A)` as shown in figure. The detector D fixed on block B attached to free end of spring `S_(B)` detects this sound. The blocks A and B are simultaneously displaced towards each other through a distance of `1.0m` and then left to vibrate. The maximum and minimum frequencies of sound detected by D, if the vibrational frequency of each block is `2Hz` are (Velocity of sound `v=340m//s`)

A source S emitting sound of 300 Hz is fixed of block A which is attached to free end of a spring S_A as shown in the figure. The detector D fixed on block B attached to the free end of spring S_B detects this sound. The blocks A and B are simultaneously displaced towards each other through of 1.0 m and then left to vibrate. Find the maximum and minimum frequencies of sound detected by D if the vibrational frequency of each block is 2 Hz (velocity of sound is 340 m/s).

A source S emitting sound of 300 Hz is fixed on block A which is attache to free end of a spring S_(A) as shown in figure. The detector D fixed on block B attached to free end of spring S_(B) detects this sound. The blocks A and B simultaneously displaced towards each other thrugh a distance of 2.0m and then left to vibrate. If the product of maximum and minimum freuquencies of sound detected by D is K + 10^(4) sec^(-2) . Find K . Given the vibrational frequencies of each block is 5//pi Hz . speed of sound in air = 300 m//s

A block of mass m is attached to two unstretched springs of spring constant k , each as shown. The block is displaced towards right through a distance x and is released The speed of the block as it passes through the mean position will be

A block of mass m is attached to two unstretched springs of springs constant k_(1) and k_(2) as shown in figure. The block is displaced towards right through a distance x and is released. Find the speed of the block as it passes through the mean position shown.

One end of a spring is rigidly fixed. A block attached to the free end of the spring is pulled through a distance x_(0) . On releasing the block, its amplitude of motion cannot exceed +-x_(0) . Why?

A block of mass m is attached to two unstretched springs of spring constants k_1 and k_2 as shown in figure. The block is displaced towards right through a distance x and is released. Find the speed of the block as it psses through the mean position shown.

A block of mass m is attached to four unstretched massless springs of spring constant k_1 and k_2 as shown in figure. The block is displaced towards right through distance x and is released. Speed of block when displacement of block is x/2 from mean position is :

A small block is connected to a massless rod, which in turns attached to a spring of force constnat (K =2N//m) as shown in the fig. The block is displaced down slightly and left free. Find its time period.
