IM sure there is C, D, and E in kuiper belts, but not really sure of silicon and iron
        
             
        
        
        
Picosecond = 10 ^ -12 seconds.
Zeptosecond = 10^ -18 seconsds
Petaseonds  =  10^15  seconds
To express Picoseconds into any of other two, you have to divide  10^-12 by the power index of the one in question
1Picosecond :   10^-12  /  10^-18 =    10^ (-12- 18) =  10^ (-12+18)= 10^6  zeptoseconds
1Picosecond :   10^-12  /  10^15 =    10^ (-12-15) =  10^-27  Petaseconds.
1Picosecond = 10^6  zeptoseconds
1Picosecond = 10^-27  Petaseconds
        
             
        
        
        
Answer:
Moment of the force is 20 N-m.
Explanation:
Given:
Force exerted by the person is, 
Distance of application of force from the point about which moment is needed is, 
Now, we know that, moment of a force 'F' about a point at a perpendicular distance of 'd' from the same point is given as the product of the force and the perpendicular distance.
Therefore, the moment of the force about the end of the claw hammer is given as:

Hence, the moment of the force exerted by the person about the end of the claw hammer is 20 N-m.
 
        
             
        
        
        
Answer:
= 0.5 m/s²
Explanation:
- According to Newton's second law of motion, the resultant force is directly proportion to the rate of change of linear momentum.
Therefore;<em> F = ma , where F is the Force, m is the mass and a is the acceleration.</em>
<em>Thus; a = F/m</em>
<em>but; F = 5 N, and m = 10 kg</em>
<em>  a = 5 /10</em>
     <u>= 0.5 m/s²</u>
 
        
                    
             
        
        
        
Because metallic bonds involve all of the metal atoms in a piece of metal sharing all of their valence electrons with "delocalized" bonds.
