A projectile launched at an angle of 45 degrees above the horizontal travels through the air. Compared to the projectile's theoretical path with no air friction,
the actual trajectory of the projectile with air friction is *

Please answer fast

It is either a  proton or a neutron im almost positive. hope this .

The anwser is: wave a has a greater pitch and frequency.

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.
