properly in the adventure that your outfits are not made up of cotton they received't shrinkmaximum outfits have some cotton yet when it has slightly quantity or none there is not any longer something to cut backThe cotton is what shrinks.
Her dryer probably gets a lot hotter then yoursDon't set the timer for an hour try a 1/2 hour or you could always take your clothes back to your home and dry them.
F 1000 + 7(10 - z), as the cable shortens, the force required to life the ball-cable system becomes smallerSo W Int{ z 0 to 10} F dzThen just evaluate the integral.
