Calculate the missing information in each question plz help mee Wave Speed = ?
Wavelength = .9 m
Frequency = 91 Hz

Wave Speed = 68 m/s
Wavelength = ?
Frequency = 146 Hz

Wave Speed = 9 m/s
Wavelength = .5 m
Frequency = ?​

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

Awind turbine is rotating counterclockwise at 0.5 rev/s and slows to a stop in 10 s. its blades are 20 m in length. (a) what is the angular acceleration of the turbine? (b) what is the centripetal acceleration of the tip of the blades at t=0s? (c) what is the magnitude and direction of the total linear acceleration of the tip of the blades at t=0s?

Often called simply "velocity," this is the velocity of an object at a particular moment in time.
