Hiii please help me At the end of a very long taut string, of mass 0.008 kg, and linear density 0.021 kg / m, a MAS is produced, perpendicular to the direction of the string, of amplitude 0.322 cm and frequency 16 Hz. If this disturbance propagates along the rope with velocity 43m / s, determine:
a. the wavelength of the generated waves.
B. The energy that these waves transmit.
C. The power that transmits the waves produced along the string.

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
