Answer:
Ionic or electrovalent bond
Explanation:
The electronegativity of an atom determines to what extent an atom would attract an electron towards it. So, they can form combine.
The nature of chemical bonding depends upon the difference between the electronegativity of the combining atoms.
When the electronegativity difference is
< 0.4 - forms non-polar covalent bonds
between 0.4 and 1.7 - polar covalent bonds
> 1.7 - ionic bond
Hence, when there is a large difference between the electronegativity of atoms, it forms ionic bonds.
Answer:
3924 N
5124 N
4004 N
2884 N
4004 N
Explanation:
m = Mass of elevator = 400 kg
g = Acceleration due to gravity = 9.81 m/s²
a = Acceleration
f = Friction force = 80 N
When the elevator is stationary only the acceleration due to gravity will be acting on it
Tension
The tension is 3924 N
The balanced force equation would be
The tension is 5124 N
When velocity is constant acceleration is zero
The tension is 4004 N
The tension would be 2884 N
When velocity is constant acceleration is zero
The tension is 4004 N
