For the answer to the question above,
we can get the number of fringes by dividing (delta t) by the period of the light (Which is λ/c).
fringe = (delta t) / (λ/c)
We can find (delta t) with the equation:
delta t = [v^2(L1+L2)]/c^3
Derivation of this formula can be found in your physics text book. From here we find (delta t):
600,000^2 x (11+11) / [(3x10^8)^3] = 2.93x10^-13
2.93x10^-13/ (589x10^-9 / 3x10^8) = 149 fringes
This answer is correct but may seem large. That is because of your point of reference with the ether which is usually at rest with respect to the sun, making v = 3km/s.
B. Ask a question - Hypothesize - Experiment - Analyze - Draw a conclusion
Explanation:
The scientific method is a systematic approach in which investigations are conducted in science.
It follows systematic manner;
- An observation in nature is made using the senses.
- Questions are then asked about such observations. This is the inquiry phase.
- A hypothesis is then formula to predict what might cause the observation.
- Experiments are then conducted
- The results are analyzed and a conclusion is drawn

Answer:
Neutral atom means the number of protons is equal to the number of electrons.
Explanation:
Answer:
Volume of balloon = 1000 cm^3
Explanation:
The head of a normal person can be assumed as a sphere with radius 10 cm.
Volume of sphere 
, where r is the radius.
We have approximate radius = 10 cm.
Approximate volume of head 
In the given options the closest value to the approximate volume is 1000 cm^3.
So, volume of head = Volume of balloon = 1000 cm^3
