Answer:
0.07 V
Explanation:
The electric field between two parallel plates is uniform, and its magnitude is given by
where
is the magnitude of the charge density on each face
is the vacuum permittivity
In this problem, we have
So, the electric field is
So now we can calculate the potential difference between the two plates, given by:
where is the distance between the two plates. Substituting, we find
The scientific method is a group of methods for examining occurrences, obtaining new information, or modifying and assimilating previous knowledge.
The methods of scientific method are:
Ask a question
Do background research
Construct a hypothesis
Experimentation
Analyze results
Draw conclusions
Report results
These tools enable the specific execution of a task or a group of tasks allowing the fulfillment of specific objectives within different stages of product development
Answer:
14.625 years
Explanation:
Because acceleration/deceleration are negligent we can simplify this problem into 2 basic parts:
First: how long before the astronaut arrives? Since the speed of the craft is 0.8 times the speed of light and the distance to travel is 6.5 light-years, the equation to answer this part is:
0.8t=6.5
solve for t by dividing by 0.8
t=6.5/0.8 or 8.125
so, she will arrive in 8.125 years.
Then, once she sends her message, it will travel towards earth at 1 times the speed of light or:
1.0t=6.5 which is just t=6.5
so, her message will arrive back to Earth (8.125+6.5) 14.625 years after takeoff.
