four tenths of a second
About 6-8 pitches
It depends on the speed of the ball.
A batter must request and then be given time from the home plate umpire. If the batter backs out of the batter's box without time being called the pitch is legal and valid.
normal 3-7 seconds
Batter is charged with a strike, ball is dead (like a time out). No runner can advance.
Depends on a lot of factors. Perception to finger movement is somewhere in the ballpark of .215 seconds "average". Average range is something like .14 to .33 seconds. Reaction times as low as .1 seconds are likely possible but hard to measure consistently. Reaction times below .12 seconds would make you part of an elite minority. Some resources to check out: www.humanbenchmark.com Normal distribution of reaction times on a specific task. www.visualexpert.com/recources/reactiontime.html Good rundown of factors that influence "reaction time".
When a baserunner makes the last out of an inning, the batter at the plate gets a fresh count to lead off the next inning.
No.
10 seconds from the time the pitcher has the ball in the circle. This rule is seldom ever enforced. The only way you will ever get this call is for the pitcher to get on the rubber and ready to pitch which will show a delay by the batter.
Because everyones reaction time is different. And 3 might be a bit too much.
The average (median) reaction time is 215 milliseconds.
in baseball the pitcher is standing 66feet 6 inch from the plate in fastpitch the pitcher is standing 43 feet from the plate ,there is less reaction time for the fastpitch batter
Only in one situation and that is if he can convince the umpires that he suffered an injury between the time he was called in and the time the batter enters the batter's box (like during his warmup pitches). Otherwise, he must pitch to at least one batter.
it depends how hard the pitch is coming or how hard the ball is hit but you have to have quick reflexes
