Why would measuring the difference between a first and second backwall echo be more accurate than between the main bang and the first backwall echo?

There is ringing on the front wall from the big bang that may interfere with detecting the back wall refections. So if you waiting for the second backwall bounce the front wall ringing should be gone and you can measure the difference between the two bounces.

How can you open the chambers in seven island?

Make sure you have a Relicanth(teach it Dig), and a Wailord. When you first enter the secret cave on Route between Pacifidlog Town and Slateport City, you will go in the middle of the brail symbols located on the backwall. Read the inscription, then use dig. The wall will open. Go inside and go to the middle of the brail symbols in the back of that room. Make sure that you have Relicanth in the FIRST slot of your Pokemon party and Wailord LAST slot of your party. Read the inscription on the wall and then three doors will be heard unlocking. They are located on Routes 105, 111, and 120.


How do you hide from both cameras on club penguin?

Hide behind the pillar on the bottom left-hand corner by clicking there until only your name can be seen. then throw a snowball at the camera labled: camera 2. aim at the eye of the camera (do this before the end of camera 1's search). that should get you full marks for that test.(To get full marks on the 'escape the blue square' test, DON'T walk to the blue square when it says. To speed up the process, throw a snowball at the box with the yellow triangle on it (that should be glowing blue)).


Where is the fuel filter located on a 1997 Honda Prelude?

That's not true, generation 4 prelude (93-96) have fuel filter on the backwall, roughly across from the steering wheel. Generation 5 (97-01) have fuel filter under brake fluid reservoir, they are hard to get to and require crow foot tool to take old filter off. Even though Honda claims they are "lifetime" filters, I'd say it's a good idea to change it around 100k.AnswerThe fuel filter is always located in one of two places. It is either located in the fuel tank, or somewhere between the engine and fuel tank. Get down under the car and follow the fuel lines from the tank forward, you will find it. If you don't see it, then it is in the tank. Answernot positive but i believe its near the firewall in the engine bay. id have to double check tho.


Where do you hide so that camera 1 and 2 cant see you during thr epf test on club penguin?

On club penguin, to become apart of the Elite Penguin Force, you have to pass the test. One of the challenges is to hide! To hide from camera 1, (the camera that is screening you all the time) step behind the pillar in the right bottom corner. To hide from camera 2,(the camera that is to the left of the big screen giving you orders) throw a snowball at it's lens. The snowball will stick and it won't see you! Hope this helps!

How do take care of a assassin bug?

I can tell you how to take care of Platymeris biguttatus, the Twin-spotted Assasin bug. P. rhadamantus, the Red-spotted assassin bug requires similar care.They can be kept in groups, they live together without problems and if you feed them enough, won't prey on each other. I often see my assassin bugs sharing as big roach, even with nymphs.I would recommend a 10 or 20 gallon terrarium or tank for a group of 20 bugs, with cork or bark pieces as hiding places. They can be kept at room temperature and require no special humidity. I use potting soil as substrate, but they are just as happy with sand, coconut fibre bedding or tissue papers. Some sort of backwall (cork for example) will give them more room to climb. If you use a tank, a tight-fitting lid is a must. The bugs don't like to fly, but they can climb glass without problems and the nymphs are tiny.Since they will leave plants alone, you can decorate the tank with such houseplants as pothos ivy, spider plant, bamboo ect. I mist the tank once every week and keep the substrate moist, for the plants and for the eggs.I feed my group every week and they get roughly one insect per adult assassin bug and some additional roach nymphs for the babies. They prey on almost anything that moves: crickets, locusts, mealworms, butterworms, but roaches are my favourite because they are easy to breed. You will need a steady supply of insects for a assassin bug colony, so breeding your own is probably a good idea. They can kill insects that are their own size, but do better with smaller prey (and the prey dies more quickly).An adult assassin bug lives for up to two years and females produce a huge number of eggs. They are about 2 millimeters long are purple, with white caps. To hatch, they need to be kept moist. You can either leave them with the adults or you check the substrate at least once a month for eggs and raise the nymphs seperately. Right after hatching, the nymphs are bright red with yellow legs, older nymphs are purple-black with black legs.Even though they have a painful bite and can spray you with defensive liquid, assassin bugs are peaceful and not at all aggressive. I don't recommend handling them, but you can take them out of the tank with their hiding places or whatever they are sitting on without problems if you want to clean the tank.
