The ideal mechanical advantage of an inclined plane or ramp  is equal to the length of incline divided by height of the inclined plane. in equation
MA = L / H
since the ideal mechanical advantage of the given inclined plane is 2 and the length of inlcine is 3.8 m
MA = L / H
H = L / MA
H = 3.8 / 2
H = 1.9 m was paco above the ground
        
             
        
        
        
This question seems to really be incomplete. You must include the options but fortunately I have already encountered this problem.
Here are the choices:
<span>A. have a different frequency than the resultant wave.
B. be in phase with each other.
C. be traveling in the opposite direction of the resultant wave.
D. have a different wavelength than the resultant wave
The correct answer is letter B. be in phase with each other</span>
        
                    
             
        
        
        
Answer:
c) 2Q
Explanation:
From the given information:
The pressure inside a pipe can be expressed by using the formula:

Since the diameter in both pipes is the same, we can say:

where;
length of the first pipe A  and the length of the second pipe B
 and the length of the second pipe B 
Since the difference in pressure is equivalent in both pipes: 
Then:




 
        
             
        
        
        
Answer:
cell swell and burst(b)
Explanation:
This process is called hemolysis. it also occurs in a red blood cell.
 
        
             
        
        
        
Yes, his velocity will decrease the further he slides.
