If a tank filled with water contains a block and the height of the water above point A within the block is 0.6 meter, the pressure at point is 5.88kPa

p= 1000 kg/m3*9.8 m/s2*0.6m = 5.88kPa.
Which of the following is true regarding the properties of light? A. Light has a dual nature and acts like both a wave and a particle. B. Light can travel only in a straight line. C. Light needs a medium to propagate through a vacuum. D. Light doesn't display interference or diffraction.
Weegy: Light has a dual nature and acts like both a wave and a particle is true regarding the properties of light. User: A wave with a period of 1 3 second has a frequency of A. 67 Hz. B. 33 Hz. C. 300 Hz. D. 3 Hz. Weegy: A wave with a period of 1 3 second has a frequency of 3 Hz. User: A wave with a period of 0.008 seconds has a frequency of A. 80 Hz. B. 12.5 Hz. C. 800 Hz. D. 125 Hz. Weegy: A wave with a period of 0.008 second has a frequency of: 125 Hz. User: If a source of sound waves is rapidly approaching a person, the sound heard by the person appears to have A. a period higher than the original period. B. a frequency higher than the original frequency. C. a pitch lower than the original pitch. D. an amplitude lower than the original amplitude. Weegy: If a source of sound waves is rapidly approaching a person, the sound heard by the person appears to have: a frequency higher than the original frequency. User: You increase the temperature from 30°C to 36°C. What's the velocity of the sound wave at this new temperature? A. 350.0 Hz B. 335.6 Hz C. 352.6 Hz D. 344.0 Hz (More)

Your boss asks you to adjust the temperature so that a sound wave travels more quickly through the air. You increase the temperature from 30 degrees to 36 degrees. Velocity of sound in air = 331.5 m/s + 0.59 m/s*°C times (the new temperature) v = 331.5 + 0.59 * 36 v= 352.6 Hz.
