Answer:
the sp³ orbital, is a very directional orbital that forms the bonds called covalent. the material is an electrical Insulator. hardness of the material comes from the energy needed to break the covalent bonds (sp³)
Explanation:
Carbon has several structures, for its different ways of bonding, in all these the orbital s is excited and mixed with the orbitals p, creating hybrid orbitals sp³, sp² and sp, there are some π orbitals around the latter.
Each type of hybrid orbital is linked differently, the sp³ orbital, is a very directional orbital that forms the bonds called covalent, where when it binds to another atom they share an electron, therefore the 4 sp³ orbitals form a stable molecule with full orbitals (8 electrons).
As the electrons are in the direction of the links, they cannot be easily moved, so the material is an electrical Insulator.
The hardness of the material comes from the energy needed to break the covalent bonds (sp³), there are only a few directions in which the links can be separated
Answer:
X = 5.44 m
Explanation:
First we can calculate the normal force acting from the floor to the ladder.
W₁+W₂ = N
W1 is the weigh of the ladder
W2 is the weigh of the person
So we have:
The friction force is:
Now let's define the conservation of torque about the foot of the ladder:
Solving this equation for X, we have:
Finally, X = 5.44 m

The speed of the cart after 3 seconds of Low fan speed is equal to 54 cm/s.
<h3>How to calculate the speed?</h3>
Mathematically, speed can be calculated by using this formula;
Speed = distance/time
At Low fan speed after 3 seconds, the distance covered is 162 cm:
Speed = 162/3
Speed = 54 cm/s.
At Medium fan speed after 5 seconds, the distance covered is 600 cm:
Speed = 600/5
Speed = 120 cm/s.
At High fan speed after 2 seconds, the distance covered is 128 cm:
Speed = 128/2
Speed = 64 cm/s.

Explanation:
A machine is an object or mechanical device that receives an input amount of work and transfers the energy to an output amount of work. For an ideal machine, the input work and output work are always the same. The six common simple machines are the lever, wheel and axle, pulley, inclined plane, wedge, and screw.
