Jillian then applies 1 mL of four different types of antibiotic to the different plates. The plates are incubated in the dark at the same temperature and humidity for one week. Jillian records the number of colonies that remain on each plate at the end of each day during the week. Her results appear below. Day 1 Day 2 Day 3 Day 4 Day 5 Day 6 Day 7
Plate 1 100 90 80 70 60 50 40
Plate 2 100 87 69 55 43 43 43
Plate 3 100 95 110 125 150 138 104
Plate 4 100 50 37 16 0 0 0

What is the outcome variable (dependent variable) in Jillian's experiment?
A.
the type of antibiotic that is used
B.
the type of bacteria that is being tested
C.
the number of bacterial colonies that remain
D.
the initial number of bacterial colonies

To understand the electric potential and electric field of a point charge in three dimensions consider a positive point charge q, located at the origin of three-dimensional space. throughout this problem, use k in place of 14? ? 0. part adue to symmetry, the electric field of a point charge at the origin must point from the origin.answer in one word.part bfind e(r), the magnitude of the electric field at distance r from the point charge q.express your answer in terms of r, k, and q. part cfind v(r), the electric potential at distance rfrom the point charge q.express your answer in terms of r, k, and q part dwhich of the following is the correct relationship between the magnitude of a radial electric field and its associated electric potential ? more than one answer may be correct for the particular case of a point charge at the origin, but you should choose the correct general relationship. a)e(r)=dv(r)drb)e(r)=v(r)rc)e(r)=? dv(r)drd)e(r)=? v(r)r
