You must look down at the wall and your feet cannot leave the starting block until the other swimmer's hand touches the wall. That is why the lane judge walks up next to the starting block and watches to see the swimmers hand touch the wall in order to make sure the next swimmer does not leave early.

on the wall their is a touch pad and when touched it goes off it is all recorded electronically, when near the end watch the side of the starting block a light will flash red.
Able bodied swimming and dissability swimming is different as where people have missing limbs extra, the rules that apply in able bodied swimming cannot apply in dissability swimming. For example, on butterfly and breaststroke, the swimmer must touch each wall with both hands, but in a dissability meet, the swimmer would not be able to do this if they only hadhalf anarm. However the swimmer still has to push their half arm foreward as if they were going to touch the wall, but once their other handhas touched, they can turn. Hope this answered your question :)
soft tissue and muscle. i think.... The outside wall of a hoof is keratin--same as fingernails.
The ends of the lanes have touch pads or sensors that respond to contact or pressure from the swimmer. When they hit the wall it stops the timer. Im sure they use other methods too.
The acceleration of the swimmer can be calculated using Newton's second law: F = ma, where F is the force applied, m is the mass of the swimmer, and a is the acceleration. Rearranging the formula to solve for acceleration, we get a = F/m. Plugging in the values, a = 250 N / 70 kg = 3.57 m/s^2. So, the swimmer will accelerate at a rate of 3.57 m/s^2.

if you dont touch the wall with both hands, you will DEFINITELY get disqualified
1. IM must fly, back, breast, free in that order 2. you cannot touch the wall on your side in backstroke 3. you must touch the wall. Period. xD 4. you must keep your feet together during fly kick 5. you must touch the wall with two hands for breaststroke 6. you must touch the wall with two hands for fly 7. you can only touch the wall with one hand for free 8. you can only touch the wall with one hand for back. thats really all i can think of.
yes they put these electronic boards on the wall and it senses it when you touch it
Yes, you can put the iPod Touch wall charger into an extension cord. That extension cord has to be plugged into a wall to be able to charge the iPod, though.
