Speed = frequency * wavelength
        
             
        
        
        
Answer:
The velocity is 40 ft/sec.
Explanation:
Given that,
Force = 3200 lb
Angle = 30°
Speed = 64 ft/s
The resistive force with magnitude proportional to the square of the speed, 

Where, k = 1 lb s²/ft²
We need to calculate the velocity
Using balance equation

Put the value into the formula

Put the value of k


At terminal velocity 
So, 


Hence, The velocity is 40 ft/sec.
 
        
             
        
        
        
Answer:
With the help of formula.
Explanation:
We can calculate the electric potential of any point through the formula of electric potential which is given below.
Electric potential =  Coulomb constant x charge/ distance of separation.
Symbolically it can be written as,  V = k q/ r where
V	=	electric potential  
k	=	Coulomb constant
q	=	charge
r	=	distance of separation
If we have all these data, we can simply put the data in the formula and we will get the value of electric potential.
 
        
             
        
        
        
When it rains, water will flow into its appropriate watershed. A ridge or topographical higher areas that connects two waters are called a divide. In the United States there is an area in the Rocky Mountain called the "continental divide." This refers to water on the east of the divide flows into the Atlantic. The water on the west side flows into the Pacific
