archerfish physics problem

This isnt good for the archerfish, because water that is more spread out will strike the insect with less pressure (force divided by area). If your line of sight to the fish is 68.0 degrees below the horizontal in air, and assuming the spear follows a straight line path through the air and water afte, It has been claimed that an insect called the froghopper is the best jumper in the animal kingdom. aquamarinegiraffe605 Lv1. Forget lullabies! Suppose the archerfish squirts water with a speed of 2.30 m/s at an angle of 52.0 degrees. Physics questions and answers; The archerfish is a type of fish well known for its ability to catch resting insects by spitting a jet of water at them. That idea stayed with me, and Empirical Zeal documents my attempts to play with the universe, to poke at it gently, and to work out what makes it tick. Archerfish are incredible creatures. The archerfish has high accuracy at distances of 1.2 m to 1.5 m, and it sometimes makes hits at distances up to 3.5 m. A groove in the roof of its mouth, along with a curled tongue, forms a tube that enables the fish to impart high velocity to the water in its mouth when it suddenly closes its gill flaps. PLoS ONE 7(10): e47867. It cannot be emphasized enough how much easier a problem will be once it is drawn out. Phys.org is a part of Science X network.

It uses science to give itself superhuman (or rather, superfish) strength -- like the Hawkeye of the animal kingdom, it's always on target and never runs out of arrows. This aptly named creature captures its prey by shooting a stream of water drops at an insect, either flying or at rest. Suppose a pelican starts its dive from a height of 19.0 m and cannot change its path once committed. It has been found that Archer fish are able to strike their prey when sighting upwards at angles of 40 degrees with the normal. Note: References These detectors, located in their noses and called ampullae, are so sensitive they, You are fishing off a bridge. As water trickles down a faucet, the stream sometimes breaks into small drops of water. 2. Herman Miller's Action office inspired a slew of copycats, which begat the dreaded office cubicle.

And, surprisingly, the soun, Lolliguncula brevis squid use a form of jet propulsion to swim. The water jet would break up into blobs due to surface tension, but the archerfish has ensured that the blobs in the rear are moving faster than the ones in front. Again, no air resistance. And now, scientists at the University of Bayreuth have learned, the fish can pack that extra punch by reinforcing the first spit with a rapid series of follow-up spits too quick to see except with a high-speed camera. DOI: 10.1371/journal.pone.0047867. Such a ray of light is said to be approaching the boundary while traveling along the normal. They eject water out of jets that can point in different directions, allowing them to change direction quickly. The trap-jaw ant can snap its mandibles shut in as little as 1.4 10^( 4) s. In order to shut, both mandibles rotate through 91 degree angle. Very cool! (A) Find the acceleration of th, Three spiders are resting on the vertices of a triangular web. The entire strike happens in just 4 hundredths of a second, or 10 times faster than the blink of an eye. Tutorials are also presented along with dozens of solvd examples. In fact, the physicists believe the technique means the animal has a striking power that is five times more than what a vertebrate muscle can generate. If it is a long problem, read and understand it in parts till you get even a slight understanding of what is going on. They strike with remarkable accuracy, and just a tenth of second after the prey is hit, they quickly move to the spot where it will hit the water. Our experts can answer your tough homework and study questions. Cleverer still is the fishs aim, as the tiny creature takes into account the way light bends as it enters water. Only he's not very good at it. This field creates a potential difference of a few volts between the head and tail, which in turn, Steelhead trout migrate upriver to spawn.
