How long does it take a packet of length 1,000 bytes to propagate over a link of distance 2,500 km, propagation speed 2.5 · 108 m/s, and transmission rate 2 mbps? more generally, how long does it take a packet of length l to propagate over a link of distance d, propagation speed s, and transmission rate r bps? does this delay depend on packet length? does this delay depend on transmission rate?

increases it

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

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

c) up is the direction the magnetic force is acting on the charge.
