Answer: North of west
 North of west
Explanation:
Given
Plane wishes to fly in west 
but wind with speed 33.9 km/h towards south obstructing its path
so plane must fly at an angle of \theta w.r.t west such that it final velocity is towards west 
Plane absolute speed=195 km/h
To fly towards west velocity in Y direction should be zero 
thus 

so Plane should head towards  North of west in order to fly in west.
 North of west in order to fly in west.
So plane 
actual velocity is

 
        
             
        
        
        
Explanation:
Centripetal acceleration is:
a = v² / r
a = (4.0 m/s)² / 0.60 m
a = 26.6 m/s²
 
        
             
        
        
        
Answer:
Check the explanation
Explanation:
A) 7th Harmonic. (Of an open ended pipe, odd harmonics are allowed (3rd overtone))
b) f = n v / 4 L
n = 7
f = 7 x 350 / 4 x 0.41 = 1493.9 Hz
c) Let level of water H, If reduces the effective length of pipe
Using, f = n v / 4 Leff
n = 1
251.8 = 1 x 350 / 4 ( 0.41 - H)
H = 0.0625m
H = 6.25 cm
 
        
             
        
        
        
In 2 days there are 48 hours
to find the average speed per hour, divide 2,387 by 48
Which gets you the answer 49.72
Which rounds up to 50
The average speed is 50mph
