Answer: the answer is radiation
Explanation: Radiation, because heat travels in all directions Convection, because heat travels in all directions Conduction, because heat travels from hot to cold Radiation, because heat travels from cold to hot. 
 
        
             
        
        
        
Answer:
surface charge density on each sphere is  C
 C
Explanation:
given data 
radius of smaller sphere = 5 cm 
radius of  larger sphere is 12 cm
electric field at surface of larger sphere = 660 kV/m = 660 × 1000 v/m
solution
we apply here electric field formula that is express as
E =  .................1
    .................1
put here value 
660000 =  
  
Q1 = 1056 ×  
 
and 
here field inside a conductor is zero so that electric potential ( V ) is constant 
 ..................2
   ..................2
so Q2 will be 
Q2 =   
   
Q2 =   C
  C
