Assuming nothing else blocks their view, approximately how far can two people stand from each other in clear atmosphere until they can not longer see each other due to the curvature of the earth ? [take : radius of earth = 6400 km] (assume height of each people is 2m) (1) 10 m (3) 1 km (2) 100 m (4) 10 km

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba
