what are the characteristic of the first one?
They are designed to open softly. During deployment, the slider slides down from the canopy to just above the risers. The slider is slowed by air resistance as it descends and reduces the rate at which the lines can spread
Parachute
Main parachutes used by skydivers today are designed to open softly. Overly rapid deployment was an early problem with ram-air designs. The primary innovation that slows the deployment of a ram-air canopy is the slider; a small rectangular piece of fabric with a grommet near each corner. Four collections of lines go through the grommets to the risers (risers are strips of webbing joining the harness and the rigging lines of a parachute). During deployment, the slider slides down from the canopy to just above the risers. The slider is slowed by air resistance as it descends and reduces the rate at which the lines can spread. This reduces the speed at which the canopy can open and inflate.

At the same time, the overall design of a parachute still has a significant influence on the deployment speed. Modern sport parachutes' deployment speeds vary considerably. Most modern parachutes open comfortably, but individual skydivers may prefer harsher deployment.

what short stories did edgar allan poe write MS. Found in a Bottle was he in military? Yes - he was in the United States Army as a private on May 27, 1827 what are some of the components of the us army? Regular Army, the Army Reserve and the Army National Guard does it have special forces? Yes - 1st Special Forces Group (Airborne), 3rd Special Forces Group (Airborne), 5th Special Forces Group (Airborne) which vehicle do they use? M1A2 Abrams, M2A3 Bradley,  Stryker, AH-64 Apache attack helicopter who produced the third vehicle? General Dynamics Land Systems does it contain weaponry? Yes -  .50 in (12.7 mm) M2 machine gun,  7.62 mm M240B machine gun, or 40 mm Mk 19 grenade launcher. what is its variant? M1256 ICVV, M1252 MCVV, M1255 CVV what are some of its mechanical features? Pneumatic or hydraulic systems and its engine features? For its powerpack the Stryker uses a Caterpillar diesel engine common in U.S. Army medium-lift trucks, eliminating additional training for maintenance crews and allowing the use of common parts. the insect name that you just mentioned, how does it effect the health of humans? Caterpillar hairs sometimes have venoms in them and species from approximately 12 families of moths or butterflies worldwide can inflict serious human injuries ranging from urticarial dermatitis and atopic asthma to osteochondritis, consumption coagulopathy, kidney failure, and brain bleeding. how is it related to economy? Caterpillars cause much damage, mainly by eating leaves.The cotton bollworm causes enormous losses. Other species eat food crops. Caterpillars have been the target of pest control through the use of pesticides, biological control and agronomic practices does it have any positive effect on economy? Yes - The silk industry is based on the silkworm caterpillar. how is the product that you just mentioned cultivated? Silk moths lay eggs on specially prepared paper. The eggs hatch and the caterpillars (silkworms) are fed fresh mulberry leaves. After about 35 days and 4 moltings, the caterpillars are ready to begin spinning a silk cocoon which industries uses it? Silk had many industrial and commercial uses, such as in parachutes, bicycle tires, comforter filling and artillery gunpowder bags.
