Rapid back and forth motion of a particle about its mean position is called _____.

A particle executes a simple harmonic motion of time period T. Find the time taken by the particle to go directly from its mean position to half the amplitude.

A closed circular wire hung on a nail in a wall undergoes small oscillations of amplitude 2^@ and time period 2s. Find a the radius of the circular wire. b. the speed of the particle farthest away from the point of suspension as it goes though its mean position c. the aceleration of this particle as ilt goes through its mean position and extreme position. Take g=pi^2 sms^-2

Consider an oscillator which has a charged prarticle and oscillates about its mean position with a frequency of 300 MHz. The wavelength of electromagnetic waves produced by this oscillator is

The position velocity and acceleration of a particle executing simple harmonic motion are found to have magnitudes 2cm, 1ms^-1 and 10ms^-2 at a certain instant. Find the amplitude and the time period of the motion.

For each natural number k, let C_k denotes the circle radius k centimeters in the counter-clockwise direction.After completing its motion on C_k , the particle moves to C_[k+1] in the radial direction. The motion of the particle continues in this manner. The particle starts at (1,0).If the particle crosses the the positive direction of the x-axis for first time on the circle C_n ,then n equal to

The maximum speed and acceleration of a particle executing simple harmonic motion are 10 cm s^-1 and 50 cms^-2. Find the position of the particle when the speed is 8cms^-1.
