Speed = (wavelength) x (frequency
Speed = (.020 m) x (5 / sec)
Speed = 0.1 m/s

pythagorean theorem : ✓a² + b² = c²
c² = a² + b² = 4 + 49 = 53
c = ✓53 km
displacement = c = ✓53 km
distance = 10 + 3 + 2 = 15 km
 
        
             
        
        
        
To develop this problem we will apply the linear motion kinematic equations. Specifically, the second law that describes the position of a body as a function of its initial velocity, time and acceleration.

Here,
u = Initial velocity
t = Time
g = Acceleration due to gravitation
If we replace the values to find the gravitational acceleration we have then,


Recall that the force of gravity on the planet Jupiter is 24.79 m / s² so the measure is closer to this planet. It is likely that you are in Jupiter.
 
        
             
        
        
        
The cross section is the little tiny circle you see when you cut a wire 
and look at the flat, cut end.
The cross-sectional area of the wire is the area of that little circle.  
It's equal to
                           Area = (pi) x (1/4) x (Diameter of the wire)²
