Describe the relationship between the tension and pitch

Wave Velocity in String. The velocity of a traveling wave in a stretched string is determined by the tension and the mass per unit length of the string. for a string of length cm and mass/length = gm/m. For such a string, the fundamental frequency would be Hz.

answer: option c.

explanation:

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
