A wave generator produces 16.0 pulses in 4.00 seconds. What is the period? 4. What is the frequency for the problem above? 5. If a water wave has 10.0 meters between crests and have a frequency of 5.0 Hz‚ what is the speed of these waves? 6. The shortest time in which a wave motion

Measure the length of the air column from the surface of the water to open end. 7. Repeat the above steps for the remaining two tuning forks. 8. Record all collected data in tabular (chart or table) format. Calculation: For tuning fork having frequency of 256Hz V = 331.4 + 0.606 X (T) V = 331.4 + 0.606 X (20) V = 343.52 Now‚ V = L F L = 343.52/256 L = 1.34 Ln = (2n-1) x L

the C-‚ Ku- and Ka-bands. C-band is the oldest allocation and operates in the frequency range around 6 GHz for transmission (uplink) and between 3.7 and 4.2 GHz for reception (downlink). Ku-band is the most common transmission format in Europe for satellite TV and uses around 14 GHz for uplink and between 10.9 and 12.75 GHz for downlink. Ka-band uses around 30 GHz up- and between 18 and 20 GHz downlink frequency. C-band and Ku-band are becoming congested by an increasing amount of users‚

WOMEN EMPOWERMENT OR MILITARY EFFICIENCY? AN ANALYSIS REGARDING THE RECENT US POLICY LIFTING THE BAN AGAINST WOMEN IN COMBAT ZONES Etana Fides Introduction History has always defined war fighting to have an inclination towards being a "males only" activity with laws and policy established to reflect and maintain that exclusivity. And yet‚ women have always been of service in and out of the warzones‚ even if "unofficially." The last fifty years have produced significant changes

Acoustic imaging can cover a width from several kilometers down to 10 meters. There is a trade off between range and resolution. This depends on the frequency that is being used. Lower frequency models are either ship mounted or towed behind to give a broad picture of the site where the higher frequencies provide a much clearer image. The next method that

Repetitive sound vibrations such as chanting‚ drumming‚ and toning have been used as part of spiritual practices to restore and rejuvenate mind‚ body and spirit. Everything in the universe is in a state of vibration。This vibration causes a natural frequency in every object including the human body. When our energy centers (Chakras) become blocked because of negative thinking‚ excessive stress and exposure to environmental factors‚ they begin to vibrate out of tune‚ and we experience “dis ease” or disease
