Answer:
Yes the frequency of the angular simple harmonic motion (SHM) of the balance wheel increases three times if the dimensions of the balance wheel reduced to one-third of original dimensions.
Explanation:
Considering the complete question attached in figure below.
Time period for balance wheel is:


m = mass of balance wheel
R = radius of balance wheel.
Angular frequency is related to Time period as:

As dimensions of new balance wheel are one-third of their original values


 
        
             
        
        
        
Answer:
Good government 
Explanation:
Many people will think its natural resources but its not. Africa is a proof. They have resources but leadership is what makes most of their countries 3rd world. #BADGOVERNANCE
 
        
             
        
        
        
If, 

then, with 3x time t, (suppose, new distance is h) 




Therefore, new distance h will be 9 times bigger than distance d.

Answer:
The capacite is C=5.32 uF using the equations of voltage and energy in capacitance  
Explanation:
The energy holds is 5 J and the resistor dissipates 2J so the energy total is 3J
Using:

Voltage in this case is the energy dissipated so



Using the equation to find capacitance 

 F
 F
C= 5.32 uF because u is the symbol for micro that is equal to 
 
        
             
        
        
        
Answer:
F = 2520 N
Explanation:
We have,
The maximum acceleration of a fist in a karate punch is 4200 m/s². The mass of the fist is 0.6 kg.
It is required to find the force that the wood place on the fist. Force is given by the product of mass and its acceleration such that,
F = ma

So, the force of 2520 N is acting on the wood.
