Question

6&7 please

A tube open at one end produces a standing wave with a fundamental frequency of 625 Hz when the temperature is -10.0°C, what is the length of the tube, in meters? b) If we wanted to produce a standing wave with the same fundamental frequency in a string with a length of 1.30 m and a mass of 4.00 g, what would be the tension in the string, in Newtons? Do not include units in your answers. a) m b) N Question 7 10 pts A 36.0C charge is placed at (-0.409m, 0.439m) and a -44.0°C is then placed at (0.154m, 0.423m). What would be the net force on a 25.0 C charge placed at the origin of this coordinate system due to the other two charges? Do not include units in your answers.
