Good evening,

can you help me with those questions

TB =Part A A sinusoidal wave with wavelength 0.500 m travels along a string. The maximum transverse speed of a point on the string is 3.00 m/s and the maximum transverse acceleration is What is the propagation speed v of the wave? 8.90 x 104 m/$2. Express your answer with the appropriate units. HA ? V = Value Units Submit Request Answer Part B K What is the amplitude A of the wave? Express your answer with the appropriate units. HA A = Value UnitsPart A Review | Constants Use these measurements to calculate the length of the wire. Assume that the weight of the wire has a negligible effect on the speed of the transverse waves. You must determine the length of a long, thin wire that is suspended from the ceiling in the atrium of a tall building. A Express your answer with the appropriate units. 2.00-cm-long piece of the wire is left over from its installation. Using an analytical balance, you determine that the mass of the spare piece is 14.5 jug . You then hang a 0.400 kg mass from the HA lower end of the long, suspended wire. When a small-amplitude transverse wave pulse is sent up that wire, sensors at both ends measure that it takes the wave pulse 28.7 ms to travel the length L = Value Units of the wire. Submit Request Answer Part B Discuss the accuracy of the approximation made in the previous part. Choose the correct statement. The mass of the wire is equal to 4.84 g . It is not negligible compared to the 0.400-kg mass. The mass of the wire is equal to 0.048 g . It is negligible compared to the 0.400-kg mass. The mass of the wire is equal to 0.48 g . It is negligible compared to the 0.400-kg mass. The mass of the wire is equal to 0.048 kg. It is not negligible compared to the 0.400-kg mass.Part A A thin string 2.50 m in length is stretched with a tension of 90.0 N between two supports.
