All the weight of the wooden board rests solely on the support situated at the center of the rod, while the other support positioned at one end experiences no reaction force, resulting in a 0 reaction force.

Thus, the reaction force at the central support corresponds to the weight of the board, whereas the end support has 0 reaction force.

Answer:

 Baseball mass:    

Explanation:

 Circumference of a baseball is calculated using 2πr = 23 cm

 Thus, the radius comes out to be 3.66 cm, which equals m

 The mass density of the baseball matches that of a neutron or proton.

 Proton mass = kg  

 Proton diameter = m

 Proton radius =   m

 Volume of the baseball is

 Now by substituting all values into the mass per unit volume equation for the baseball, we get:  

         

           

         

       Therefore, the baseball mass amounts to
