I suppose it wouldn't have been a common occurance, but I wouldn't label it impossible. When wind hits sails -- especially a strong gust -- it can easily haul a man or maybe even two or three right off his or their feet. I have personally watched a fellow get dragged right across the stern of a small tall ship when the wind grabbed the sail and caught him off guard. In order for someone to end up upsidedown, he would have to get his foot somehow wrapped in the line that was attached to the sail that got grabbed by the wind. It would have to be securely wrapped, too. And, it would have to be one of the lines that is attached to a tackle aloft somewhere ... so, I suppose it is possible for it to happen, but not entirely likely.
What are the similarities between a bat and an owl?
They have wings and navigate largely by "SONAR".
Other than that they have almost no similarities as owls are birds and bats are mammals.
How would you describe economic development?
Economic development, generally speaking, is a process of change that is focused on the betterment of the community, state, and/or nation.
Peak DetectorA peak detector determines the peak voltage on an ac wave and converts it into a dc voltage. A diode puts the peak voltage on a capacitor. The second op amp is a buffer. This means it holds the same voltage input and output, but it allows current to be used at the output without altering the voltage. An op amp buffer is created by connecting the output to the inverting input.The purpose of the buffer in this instance is to tell the first op amp what the voltage is on the capacitor. In simple designs, this is done by simply connecting the inverting input of the first op amp directly to the capacitor. But the buffer allows a second diode to be used in the feedback loop without altering the capacitor voltage. The diode then pulls against the output of the buffer instead of the capacitor.The purpose of the feedback diode is to prevent the output from saturating on the down-swing. Saturation means the output goes to the supply rail, while excess current is drawn through the input, which can create undesirable effects. The feedback diode pulls the inverting input down to the same level as the noninverting input, which means the output is never more than 0.6V lower than the noninverting input or the bottom of the voltage swing on the ac input wave. The feedback resistor allows a difference in voltage to be created between the inverting input and the output of the buffer.The design challenge of a peak detector is in the fact that the diode pulls the voltage up but not down. Something needs to bring the dc voltage on the capacitor back down, either when the voltage being measured decreases, or when an over-voltage spike is created for some reason such as noise, contact of leads or turn on of the device.Leakage current through the diode when reverse biased will be enough to control the capacitor voltage when stable measurements are being made. At other times, more current is needed to bring the capacitor voltage down. A resistor can be used for that purpose. But it will then create some ripple on the capacitor, because it will be pulling voltage down while the diode is not pulling it up. The ripple is greatest for lowest frequencies, because then there is more time during each cycle for voltage to decrease. Therefore, low frequencies require some compromise between ripple on the dc and rate of equilibration.Here's how to calculate ripple on the capacitor. Start with this formula: V/S = I/C. It says volts per second equals current over capacitance. Say there is one volt on the cap. Divided by 10M of resistance equals 0.1µA of current. Divided by 0.47µF equals 0.213 volts per second. If the frequency is 10Hz, there is 0.05 seconds for each half of the wave. So 0.213V/S times 0.05S equals 11mV of ripple. If the frequency is increased to 1KHz, a half wave is 0.5mS, and ripple is 0.0005 × 0.213 = 0.11mV. If the cap voltage is increased to 2V, the ripple is 0.21mV, or twice as much, but the same percent.The rate at which the voltage equilibrates is not linear. At 1V on the cap, it is 0.213 volts per second; but at 2V, it is 0.426V/S. So it would take about 3-5 seconds to equilibrate when 1V too high. Pulling it down instantly with a push button switch is so easy that it is better than compromising the design or waiting for equilibration.
Qigong originated before recorded history. Scholars estimate qigong to be as old as 5,000-7,000 years.
Does sonar uses sound waves to measure water depth?
Yes.
Active sonar generates a pulse, the echo is heard some time later. The time it takes for sound to travel from the generator to the reflector and back to the sensor discloses the distance from the sonar equipment to the object reflecting the sound waves.
Passive sonar just listens and does not generate any sound pulses itself but through various analysis algorithms certain information about the distance to an object that does make sound can be obtained. Passive sonar is not used for finding the depth of water but for listening to ships.
Does walmart sell retractable vampire fangs?
No. Target sells them for $9. They are out at the store and online. So that means no.
What date did the sacrifice fly rule change from an at bat to not an at bat?
As long as the sacrifice fly has been a part of the MLB rules the batter has not been charged with a time at bat. However, the rule has been discontinued and continued several times. MLB started the sacrifice fly rule in the 1908 season. It was discontinued in the 1931 season only to become a rule again in 1939. It was discontinued again in 1940 and restarted in 1954.
So there was no sacrifice fly rule in MLB prior to 1908, between 1931-1938, and between 1940-1953.
Why don't aluminum bats break as easy as wooden bats?
Aluminum is much stronger than ash wood, and the handle of an aluminum bat is a thin cylindrical tube with reasonably thick walls (thicker than the barrel portion). As such, the bat handle is very strong and will not break. The barrel, where the walls are thinner, may dent - or even crack if the walls are too thin, the but bat will not break. New alloys and treatment processes (cryogenic treatment) even improve the strength of the aluminum further
What part in the Body makes a Vampire Bat change into a person?
the metosora this part is found near the heart. the bat can change into a human when ever it feels like. you can tell if its a vampire by its eyes(the bat) if there red its a vampire if not then its a normal bat the metosora this part is found near the heart. the bat can change into a human when ever it feels like. you can tell if its a vampire by its eyes(the bat) if there red its a vampire if not then its a normal bat
How would you describe a value chain?
Identification of all such processes within an organization along with a specification of the relationships among them provides a value chain.
What do fruit bats and horses have in common?
Both are mammals. Both have fur and give birth to live young. Both are consumers who live on plant matter. Both have long "noses." Both like fruit.
Does daken still have 3 claws?
Technically speaking, he does, but Wolverine cut off his wrist claws and they are in the process of growing back so you don't see them very much.

Why are some baseball bats black?
Baseball bats are made from either wood or aluminium. They can be stained or sprayed almost any colour. A black bat will not reflect the lights of the stadium as much as a silver coloured bat.
Why do vampire bats live in Central and South America?
They live there because of the climates. And the caves provide shelter for during the day.
"Radar the Bat" was a Beanie Baby stuffed plush from TY toys, produced beginning the day before Halloween, October 30, 1995. Later "bat" toys included "Batty the Bat" (1996) and "Bat-E" (2003). (see related link)
