Answer:
Conductors.
Explanation:
Conductors allow the flow of electrons i. e. the current and where some of the electrons energy gets converted into heat while some electrons energy converted into light. Conductors are the materials which has the ability to allow heat and electricity to flow through them. Metals such as gold, copper, Silver, Aluminum, Mercury, Steel, Iron and salty water etc are good conductors of heat and electricity.
 
        
             
        
        
        
Answer:
The value is 
Explanation:
From the question we are told that 
     The mass of each sphere is 
      The length of the string is   
 
      The angle of with the vertical is 
       The acceleration due to gravity is 
Generally the force acting between the forces is mathematically represented as 
        
=>     
Generally from Pythagoras theorem the radius of the circular curve created by the force is 
          
=>      
=>       
  
=>     
=>      
=>      
 
        
             
        
        
        
From the geometry of the problem, the 20 m-long cable creates
the hypotenuse of a right triangle, with the extended of the other two sides of
size 20 m * cos(30 deg), which is around 17.3 m. Therefore, the ball has increased
by 20 m - 17.3 m = 2.7 m. 
The potential energy will have altered by m*g*h, which is 1400 kg * 9.8 m/s^2 *
1.6 m , or about 37044 joules.
 
        
                    
             
        
        
        
Answer:
the middle 
Explanation:
the left one bulb gets power from the outher bulb 
the one on right has more bulbs
 
        
                    
             
        
        
        
neutron star is formed when the core of a star, that was one ginormous, collapse on its own mass thus it loses it's volume exponentially (y=a^x) while the mass of the star decreases linearly (y=mx+c) thus the neutron star has mass of 10 to 29 sun in the radius of 10 km( for scale earth has 6731 km) thus it's density is super high!!!!!!!!!!!!!!!!!!!
hope it helps you! ;)
