Why is the following situation impossible? An astronaut on the Moon is studying wave motion using the apparatus discussed in Example 16.3 and shown in Figure 16.12. He measures the time interval for pulses to travel along the horizontal wire. Assume the horizontal wire has a mass of 4.00 g and a length of 1.60 m and assume a 3.00-kg object is suspended from its extension around the pulley. The astronaut finds that a pulse requires 26.1 ms to traverse the length of the wire.

Solution Summary: The author explains that the gravity used in the problem is much higher than the actual value of gravity at moon. The sum of forces acting on an object is zero.

You attach a speaker to an air track cart and then attach the cart to one end of the air track by means of a spring and start the system oscillating by stretching the spring 0.597 m from its equilibrium position and then releasing it. The force constant for the spring is k = 32.8 N/m, the total mass of the speaker and air track cart are 4.00 kg, and the speaker emits sound with a frequency of 345 Hz. If your lab partner Pat stands at the end of the air track, determine the highest and lowest frequencies she hears. The speed of sound in air is 343 m/s. (Enter your answers to at least the nearest Hz.)
a) What is the highest frequency?
b) What is the lowest frequency?
The upper end of a 3.7-mm-long steel wire is fastened to the ceiling, and a 44 kgkg object is suspended from the lower end of the wire. You observe that it takes a transverse pulse 0.049 ss to travel from the bottom to the top of the wire.
What is the mass of the wire?
