Answer:
The capacitance is 1.75 nF
Explanation:
From the question we are given that 
     The inner radius is 
      The outer radius is 
     Length of the capacitor is 
     The dielectric constant is 
    The dielectric constant is  
Generally the capacitance of a capacitor can be mathematically represented as 
                 
                    
                   
                   
                   
                   
                     
 
        
             
        
        
        
Answer:
7.328m/s
Explanation:
Given parameters: 
height of table = 0.68m
final velocity of the ball = 6m/s 
Unknown: 
Initial velocity of ball = ? 
Solution: 
To solve this problem, we are going to employ the appropriate motion equation. 
We must understand that this fall occurs in the presence of gravity; 
             V = U + 2gH 
Where; 
  V is the final velocity
  U is the initial velocity 
  g is the acceleration due to gravity
  H is the height of the pool table
     Since U is the unknown, let us make it the subject of the expression; 
            U = V - 2gH 
         U = 6 - (2 x 9.8 x 0.68)  = 7.328m/s(deceleration)
 
        
             
        
        
        
Alike - both part of the light spectrum, cannot be seen with the naked eye
Different - IR is less energetic than UV, UV has a shorter wavelength than IR
IR - infrared
UV - ultraviolet
        
             
        
        
        
The answer is 300 feet. The stop lamp or lamps on the rear of a vehicle must show a red light that is set in motion upon application of the service or foot brake and, in a vehicle manufactured or assembled on or after January 1, 1964, must be visible from a distance of not less than 300 feet to the rear in normal sunlight. Take note, if the vehicle is manufactured or assembled January 1, 1964, the stop lamp or lamps must be visible from a distance of not less than 100 feet. Also, the stop lamp may be combined with one or more other rear lamps.
