It's going to depend on the vertical gradient of refractivity in the atmosphere.
That directly affects the curvature of a beam of light or radio etc., so it directly
determines how far away the horizon is. Of course, maximum line of sight is
double the distance to the horizon.
Let's assume that the vertical gradient is zero, corresponding to a K-factor of 1,
meaning simply that the light doesn't curve at all, and follows a perfectly straight
path through the atmosphere between the tops of the towers. This is not too
common, but it's the way everybody always visualizes the situation ... as if light
doesn't bend ... and it makes the arithmetic easier.
We want d1d2/(1.5K) = 100-ftwhere d1 and d2 are the distances from each tower
to the horizon, or 1/2 of the total distance, and K = 1.
d2 = 150 and the total distance = 2d = 2 sqrt(150) = 24.5 miles (rounded)
(If you're following closely, you should be screaming in great irritation because of
the cavalier way in which we started with quantities in feet, and suddenly came up
with an answer in miles. You're entirely correct. The only reason that works is that
the number of feet in 1 mile happens to be so close to 1.5 times the number of miles
in the radius of the earth. That's the reason for the 1.5 in the denominator of the
deceptively simple formula highlighted above, and the reason why that formula is
only good for feet and miles, not for meters and Km.)
The absolute value is the distance between a number and zero on a number line.

Line of sight
oof
your line-of-sight is greater than 30 seconds ahead
a resistor
radio signal bents around the curvature of earth and hence travel longer distance than the line of sight signal. At ultra high frequencies signal follows the line of sight path and hence maximum communication distance is limited due to curvature of earth for given height of transmitting and receiving antenna
Smaller as their distance from the observer increases.Foreshortened: the size of an object's dimensions along the line of sight are relatively shorter than dimensions across the line of sight.
600mm is the distance between two conductors in 11kv line
The absolute value is the distance between a number and zero on a number line.
The distance between these numbers is 48.
Actual distance travel is the total distance you actually traveled, including all the loops and curves. Straight line distance is the direct distance between the 2 places, in a straight line without a curve
