Next, she places all four plants on the same windowsill, so they all receive the same amount of light each day. plant 1 stays in
the same position throughout the experiment. plant 2 is turned 180 degrees every 12 hours. plant 3 is turned 180 degrees every
24 hours. plant 4 is turned 180 degrees every 48 hours.
mrs. fairchild monitors the plants daily. she counts the number of leaves on each side of the plant, and she uses a protractor to
measure how far each plant is leaning away from the stick.
what is the test variable (independent variable) in the experiment?
pls

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.
