Explanation:
To find the answer use the equation speed of light=wavelength multiplied by frequency (c=lambda*f) by substituting the value for the frequency the the speed of light
 
        
             
        
        
        
The Newton’s law Nikolas would use to come up with this idea is the <span>Third law that states:
</span><span>When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.
</span>
So, in this case, let's name the first Body 
A which is the skateboard and the second body 
B which is <span>the compressed carbon dioxide in a fire extinguisher. Then, as shown in the figure below, according to the Third law:

Explanation:
Given parameters: 
Distance  = 15miles north = 24140.2m
Initial velocity  = 0m/s 
Final velocity  = 4m/s 
Unknown: 
Speed, velocity and acceleration = ? 
Solution: 
The speed is the distance divide by time. It is a scalar quantity and has no directional attribute. 
   Speed  =  
  
   The speed of the student is 4m/s 
Velocity is the displacement divided by time. It is a vector quantity which specifies the direction and magnitude; 
     Velocity  =  
  
    The velocity of the student is 4m/s due north 
Acceleration is the change in velocity with time; 
      To find the acceleration, we use 
       v²  = u² + 2as 
v is the final velocity 
u is the initial velocity 
a is the acceleration
s is the distance 
      4² = 0² + 2x a x 24140.2 
        a  =  = 0.00033m/s²
  = 0.00033m/s²
 
        
             
        
        
        
Answer:
49.85 V
Explanation:
u = 0, s = 5.62 cm, t = 1.15 x 10^-6 s
Let the electric field is E and voltage is V.
Use second equation of motion
s = ut + 1/2 a t^2 
5.62 x 10^-2 = 0 + 0.5 a x (1.15 x 10^-6)^2 
a = 8.5 x 10^10 m/s^2 
m x a = q x E
E = m x a / q
E = (1.67 x 10^-27 x 8.5 x 10^10) / (1.6 x 10^-19)
E = 887.19 V/m
V = E x s 
V = 887.19 x 5.62 x 10^-2 = 49.85 V
