Florence Griffith-Joyner recorded a time 10.61 seconds (wind reading +1.2) in the final at the 1988 U.S. Olympic Trials the wind reading for this race is not in doubt, and the performance should be the official IAAF women's 100-m world record
Work = force * distance
W = F * d
Infrasound versus Ultrasound: Infrasound is sound that is beneath the lower furthest reaches of human hearing, under 20 Hz, and ultrasound is over the maximum furthest reaches of human hearing, over 20,000 Hz. People use infrasound - this repeat run for checking seismic quakes and volcanoes, charting rock and oil improvements under the earth. Infrasound is depicted by an ability to get around blocks with little dispersing.
For example, a couple of animals, for instance, whales, elephants and giraffes pass on using infrasound over huge distances. Heavy slides, volcanoes, seismic quakes, ocean waves, water falls and meteors produce infrasonic waves. Indicative ultrasound, moreover called sonography or definite clinical sonography, is an imaging method that uses high-repeat sound waves to make pictures of designs inside your body. The photos can give significant information to diagnosing and treating a variety of infirmities and conditions.
Answer:
the buoyant force on the chamber is F = 7000460 N
Explanation:
the buoyant force on the chamber is equal to the weight of the displaced volume of sea water due to the presence of the chamber.
Since the chamber is completely covered by water, it displaces a volume equal to its spherical volume
mass of water displaced = density of seawater * volume displaced
m= d * V , V = 4/3π* Rext³
the buoyant force is the weight of this volume of seawater
F = m * g = d * 4/3π* Rext³ * g
replacing values
F = 1025 kg/m³ * 4/3π * (5.5m)³ * 9.8m/s² = 7000460 N
Note:
when occupied the tension force on the cable is
T = F buoyant - F weight of chamber = 7000460 N - 87600 kg*9.8 m/s² = 6141980 N
