One end of a stretched ideal spring is attached to an airtrack and the other is attached to a glider with a mass of 0.360 kg. the glider is released and allowed to oscillate in shm. if the distance of the glider from the fixed end of the spring varies between 2.05 m and 1.06 m, and the period of the oscillation is 2.15 s, find the force constant of the spring, the maximum mass of the glider and the magnitude of the maximum acceleration of the glider.

An air bubble of volume 20 cm³ is at the bottom of a lake 40 m deep, where the temperature is 4.0°c. the bubble rises to the surface, which is at a temperature of 20°c.take the temperature of the bubble’s air to be the same as that of the surrounding water. just as the bubble reaches the surface, what is its volume?
