(1) Oil droplets are introduced into the space between two flat horizontal plates 5.0mm apart.
The plates voltage is then adjusted to exactly 780V so that one of the droplets is held
stationary. Then the plate voltage is switched off and the selected droplet is observed to fall
a measured distance of 1.50mm in 11.20s. Find the mass and the charge on the droplet

step-by-step explanation:

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
