Answer:
they are metals so they are:-
-malleable
-ductile
because metallic bonding is the same in all direction throughout the solid
Answer:
Explanation:
Given parameters:
Density of cobalt = 8.9gcm⁻³
Mass of cobalt = 17.8g
Solution
Density can be defined as the mass per unit volume of a substance:
Density = 
The unknown in the problem is Volume:
Volume = 
Volume = 
= 2cm³
Newton's third law (for every action, there is an equal and opposite reaction) means that in every interaction (in this case, that of the objects in the image), there is a pair of forces acting on the two interacting objects. <span>When you sit on a chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body. There are two forces resulting from this interaction - a force on the chair and a force on your body. This is embodied in the image by the two objects exerting force on each other (indicated by the arrows).</span><span>
