A hypnotist's watch hanging from a string swings back and forth every 0.95s. What is the frequency of oscillation in HZ
Mars rotates on its axis once every 24.8 hours. Part A What is the speed of a geosynchronous satellite orbiting Mars? Express your answer with the appropriate units. Part B What is the altitude of a geosynchronous satellite orbiting Mars? Express your answer with the appropriate units.
A round-robin tournament is an event wherein every competing team plays every other team once and only once. Assuming no ties, every game can be depicted on a graph G using a directed edge (x, y), where team x has defeated team y. (a) Assuming n teams participate in a round-robin tournament, how many vertices and edges will graph G depicting the tournament have? (b) Is it preferable to be a source or a sink in graph G? (c) Can...
Suppose that you find the fundamental frequency at 45.0 Hz. This means that the entire string forms a wave with a single anti-node. At what frequency (in Hz) do vou expect to sce the fourth harmonic (four anti-nodcs)기 expcct to see the fourth harmonic standing wave at Hz.
Answer QUESTION 5 Describe what happens at the molecular level once equilibrium is reached--that is, once the solution is saturated with Cu(IO_3)_2. Why must some solid remain in contact with a solution of a sparingly soluble salt in order to ensure equilibrium? Describe how you are going to calculate the [Cu^2+] for the saturated solution of copper iodate once you know the absorbance value of the copper ion. How will you use this concentration to find the K_sp value for...
Suppose that the frequency of an ideal spring at the first harmonic is 20.0 Hz and the wavelength of the wave is 4.0 m. At the fourth harmonic, what would be the wavelength, the frequency, and the speed of the wave? The frequency of the standing wave when there is one loop is called the fundamental frequency of the first harmonic. In general, what statement can be made about the degree to which the frequency at each of the harmonics...
