stephen stigler determined in 1977 that the speed of light is 299,710.5 km/sec. in 1882, albert michelson is there enough eviden
1 answer:
Answer: hi your question is incomplete attached below is the complete question
answer :
- population parameter( μ ) : mean speed of light measured by Albert Michelson
- null hypothesis ( H₀ ) : μ = 299,710.5km/s.
- Alternate hypothesis ( Hₐ ) : μ ≠ 299,710.5 km/sec
- Random variable : Speed of light measured by Albert Michelson.
Explanation:
Using the information provided in the question attached I will match each term with its corresponding meaning
- population parameter( μ ) : mean speed of light measured by Albert Michelson, here the parameter of interest is the speed of light measured/recorded by Albert which is represented as population mean μ
- null hypothesis ( H₀ ) : μ = 299,710.5km/s. given that the test is to determine if the speed of light recorded by both scientists are the same
- Alternate hypothesis ( Hₐ ) : μ ≠ 299,710.5 km/sec. given that the test is to determine if the speed of light recorded by both scientists are the same
- Random variable ( x ) : Speed of light measured by Albert Michelson. her we are trying to bring to conclusion data measured by Albert Michelson

Answer:
i) C decreases
ii) Q remains constant
iii) E remains constant
iv) ΔV increases
Explanation:
i)
We know, capacitance is given by:
<em>In this case as the distance between the plates increases the capacitance decreases while area and permittivity of free space remains constant.</em>
ii)
As the amount of charge has nothing to do with the plate separation in case of an open circuit hence the charge Q remains constant.
iii)
Electric field between the plates is given as:
where:
charge density,
<em>As we know that distance of plate separation cannot affect area of the plate. Charge Q and permittivity are also not affected by it, so E remains constant.</em>
iv)
- From the basic definition of voltage we know that it is the work done per unit charge to move it through a distance.
- Here we increase the distance so the work done per unit charge increases.
