Which of these events is an example of resonance? a bridge collapses due to the overloading of vehicles using it. a baker kneads dough by pounding it repeatedly. the sound of two guitars changes from loud to soft every second. an ambulance siren rises and falls in frequency as it passes you by. an opera singer breaks a thin glass with only the use of her high frequency voice.

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping

Place me with this question is my last question

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?
