A rope has a mass of 1.5 kg and a length of 6.7 m. It is fixed at both ends. If the frequency of the first harmonic on this rope is 1.2 Hz, what is the tension of this rope in N? Enter a number with one digit behind the decimal point.A traveling wave is described by the equation y(x,t) =( 0.04 m) cos(25.4 x + 216 t ), where x is measured in meter and t in seconds. What is the velocity of this wave in units of m/s? Enter a number with one digit behind the decimal point. Remember that in one dimension the sign of the velocity functions as the direction indicator
