Answer:
12N
Explanation:
Force acting on any body is equal to mass of body multiplied by acceleration produced in the body.
Its formula is
F = M*a
where F is the force acting on body
M is the mass of the body
a is the acceleration produced in the body
Unit of force is Newton represented by N
1 N is force acting on body of mass 1 kg which produces acceleration of 1m/s^2.
_____________________________________
Given
a = 0.50 m/s^2
M = 24 kg
therefore
F = 24*0.5 = 12 N
Thus, magnitude of the boy's pushing force is 12 N.
Answer:
Explanation:
because it wouldnt connect
b-a smooth surface on a rough surface
c-a rough surface and air
d-a rough surface on a rough surface
B). Does not dissolve in water
C). Forms crystal structures
D). Does not conduct electricity
Answer:
The answer is D
Explanation:
Ionic compounds have high melting and boiling points.They can dissolve in water.And they donot form crystal structurs by dissolving.And they donot conduct electricity.
Table salt (an ionic compound) forms crystal structures, similar to other ionic compounds, due to the strong electrostatic forces holding its ions in a well-organized lattice. So the correct option is C.
The property of table salt, which is also a property of other ionic compounds, is that it forms crystal structures. Table salt, like all ionic solids, exhibits a crystalline structure because its ions are held together by strong electrostatic forces of attraction in a rigid and well-organized lattice. In contrast, ionic compounds typically have high melting points, dissolve in water, and can conduct electricity when dissolved or molten because ions are free to move, allowing for the flow of electric charge.
