A water wave passes a boat. An observer on the boat notices that 120 water waves pass the boat in a time of 1 minute. The boat is at anchor (it is not moving). a Calculate the frequency of the water waves in hertz, Hz.

b The water waves have a wavelength of 1.8 m. Calculate the wave speed of the water waves.

If a substance is in the gas phase, which of qualities of the gas will stay constant? a: volume b: mass c: shape d: position of particles

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
