Solve the each part of following question:
Question: A 2.00-m string of mass 0.040 kg is tied to the ceiling at its upper end, and the lower end supports a weight W. When you pluck the string slightly, the waves traveling up the string obey the equation y(x, t) =9.00mm sin(2.50(rad/m)x+2000 (rad/s)t).
Question 1: What is the wavelength?
Question 2: What is the angular frequency?
Question 3: What is the speed of propagation of the wave?
Question 4: How much time does it take a pulse to travel the full length of the string?
Question 5: What is the weight W?
Question 6: What is the maximum transverse speed of the wave?
Question 7: What is the equation for waves traveling down the string?
I need expert help for the above questions.
