Explanation:
Answer:
563.64 m
Explanation:
Given that as per the question
x = 5 cm = 0.05 m
D = 4.2 × 107 m
d = smallest aperture size
As per the situation the solution of the smallest aperture telescope that she can get away with is below :-
We will use Rayleigh's diffraction limit which is

The equation will be
d = 563.64 m
So, the answer is d = 563.64 m
Answer:
B.6.86 m
Explanation:
Given that
Compression in spring ,x= 9 cm
Spring constant ,K= 830 N/m
Mass of the rocket ,m= 50 g = 0.05 kg ( 1 kg = 1000 g)
Now by applying energy conservation


Now by putting the values ( we are taking g= 9.81 m/s²)

h= 6.853 m
Therefore the answer is B.
B.6.86 m
