As dry air rises, it expands, and this causes it to cool about 1 degree celsius for every 100 meter rise, up to a height of 12 km. if the ground temperature is 27â write a formula for the temperature t in terms of the height h (where h is measured in meters and less than 12 km) above ground.

For 0 <= h < 12000 
t = 27 - int(h/100) will give a whole number answer for t. int means take the integer part of the division. If you don't care about whole number answers, you can write it as
t = 27 - h/100

Julia would be observing a. static electricity was caused by her sweater rubbing against her shirt and transferring electrons. she didn't touch anything metal, so that would cancel out b.she most likely didn't rub her sweater against her hair either, so that cancels out c.she also didn't scoot across the carpet while trying to take her sweater off, that cancels out d.so that leaves a.a. is correct.
