To solve this problem we will apply the concepts related to the electric field such as the smelting of the Force and the load (In this case the force is equivalent to the weight). Later we will apply the ratio of the total charge as a function of the multiplication of the number of electrons and their individual charge.

Here,
m = mass
g = Acceleration due to gravity
Rearranging to find the charge,

Replacing,


Since the field is acting upwards the charge on the drop should be negative to balance it in air. The equation to find the number of electrons then is

Here,
n = Number of electrons
e = Charge of each electron

Replacing,


Therefore the number of electrons that reside on the drop is 
Answer:
A fire hose must be able to shoot water to the top of a building 35.0 m tall ... Water enters this hose at a steady rate of 0.500 m3/s and shoots out of a round nozzle. ... I know that Flow rate=0.500 m3/s=A*V. I know the pressure needed to ... The first equation has no potential while the second has no kinetic.

The container that most likely contains a liquid is container A.
Let me know if this helped or not! :)
Answer:
from vacuum to air
Explanation:
Refraction is a property of lightwave, in which it changes speed as it passes the boundary between two media.
- When light travels from a denser medium to a less dense medium, the light wave speeds up and bends away from the normal.
- Also when light travels from a less dense medium to a denser medium, the light wave slows down and bends toward the normal.
The correct option must be from a less dense medium to a denser medium.
density of glass = 2500 kg/m³
density of air = 1.275 kg/m³
density of ice = 919 kg/m³
density of water = 1000 kg/m³
density of plastic = 940 kg/m³
density of vacuum = 6.5 x 10⁻²⁷ kg/m³
The two possible options are;
from ice to water
from vacuum to air
The difference in densities of ice and water is not larger compared to vacuum and air.
If you are required to choose two options, the two options are correct
But if it is only one option, then from vacuum to air is the correct answer.
Therefore, the correct option is from vacuum to air
