Liquid water is not itself wet, but can make other solid materials wet. Wetness is the ability of a liquid to adhere to the surface of a solid, so when we say that something is wet, we mean that the liquid is sticking to the surface of a material.
The answer is A
Hope that helps!
So you problem ask to find or calculate the approximate diameter of the planet Neptune, based on my calculation the diameter of Planet Neptune would be 5972. I hope you are satisfied with my answer and feel free to ask form more.
Answer:
a) L= 3568 m
b) 9×10^{-5} sec
c) 8.92×10^{-5} sec
Explanation:
runway length on the Earth L_o = 3600 m
Speed of the spacecraft flying past v= 4.00×10^7 m/s
then Einstein's length contraction theory,
Solving we get L= 3568 m
b) Time interval for an observer on earth when the spacecraft is directly over one end of the runway until it is directly over the other end.
L_o= 3600 m
speed v= 4.00×10^7 m/s
Then time interval Δt = L_o/v= = 9×10^{-5} sec
c) for the pilot the time interval will be
Δt_o = L/v = = 8.92×10^{-5} sec
