Answer:
Efinal / Einitial = 1
Explanation:
Applying Gauss´s Law to a closed spherical surface encircling the sphere of radius R, it can be showed that the electric field, at a distance r> R, behaves like all the charge of the sphere (which is distributed over the surface) were concentrated in the center, so the sphere produces the same electric field as the one created by a point charge located at that point.
The expression for the field E initial is as follows:
So, at a distance r> R, as the center of the sphere is located at the same point, the electric field will be the same as before.
The expression for E final is as follows:
So the ratio 
is equal to one.
Forensic scientist and technicians who work with law enforcement to solve crime, they use electron microscope the physical evidence collected from the crime scene. Microbiologist frequently use microscope to identify bacteria, and other microorganisms. Microbiologist who work with the smallest forms of life like viruses have to use electron microscope.
Answer:
To the nearest integer, the penny's speed in m/s be right as it reaches the ground if it was dropped from rest = 91 m/s
Explanation:
We have equation of motion
S = ut + 0.5at²
Here u = 0, a = g and t = 9.3 s
We have equation of motion v = u +at
Substituting
v = u +at
v = 0 + 9.8 x 9.3 = 91.14 m/s
To the nearest integer, the penny's speed in m/s be right as it reaches the ground if it was dropped from rest = 91 m/s
