Answer:
zenith distance = 39 degree
Explanation:
given data
declination of star = -13.00º
latitude = 26.00º N
to find out
distance in degrees between the star and zenith
solution
we know the formula that is
latitude = star declination+ its zenith distance ....................1
and
zenith distance = latitude - star declination
zenith distance = 26 - ( -13 )
zenith distance = 26 + 13
zenith distance = 39 degree
If the coast-to-coast distance is about 2900 miles, it will take about ...
... (2900 mi)/(186000 mi/s) ≈ 15.6 ms
for the signal to travel coast-to-coast at light speed.
_____
There are time delays due to the amplifiers and repeaters required in the path, and due to the fact that the signals don't actually travel at the speed of light in a wire.
A test of internet speed between Seattle and Washington, DC shows a round-trip time of about 87 ms when traffic is light. Modern communication channels tend to be faster than the telegraph (especially when measured in words per minute).
"we hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights." last two phrases talk about how all men created equal.
