Average velocity of a particle executing SHM in one complete vibration is:

Two springs are connected to block of mass M placed on a frictionless surface as shown below. If both the springs have a spring constant $$k$$​. the frequency of oscillation of the block is:

Two masses $$\text m_1$$​ and $$\text m_2$$​ are connected by a massless spring of spring constant k. The system is free to oscillate along the length of spring. The system oscillates with a frequency:

The period of a pendulum is given as $$T = 2\pi \sqrt{\frac{l}{g}}$$​ where g = 9.81 m/s² and π = 3.1416. The period of a pendulum of length 1 m correct to the first place of decimal in seconds is
