Explanation:
a) Three types of chemical bondings:
- Ionic bonding: Complete transfer of electrons from an electropositive atom to an electronegative atom.
- Covalent bonding: Equal sharing of electrons between the atoms with less or zero electronegativity difference.
- Metallic bonding: The bonding between the conduction electrons(electron cloud of delocalised electrons) and positively charged metal ions
b) Those elements are named as Noble gases which inert in nature that is less reactive due to fully filled electronic configuration.
Their general electronic configuration is given by:
n = principle quantum number
c) In an ionic bonding, electrons are transferred to the electronegative atom from the electropositive atom.
Electronegative: An atom which gains an electrons.Negative charge carrying ion is formed.
Electropositive : An atom which looses electrons.Positive charge carrying ion is formed.
d) This because the band width between the conduction band and valence band is large due to which electrons will not able to jump from valence band to conduction band.This makes the non metal poor electrical conductors.
Answer:

2.) 237m
Explanation:
Hello!
To solve this exercise follow the following steps, the description and complete process is in the attached image
1. Draw the full sketch of the problem.
2. The work is defined as the product of the trajectory by the force that is parallel to this direction, for this reason to find the work done we multiply the horizontal distance (250m) by the applied force (454N)
3. The potential energy is equal to the product of mass, gravity and height and is equal to the work done by the force applied by the cyclist, of this relationship and using algebra we can find the height that the cyclist climbed
4. We use the sine function to find the diagonal distance using the height and angle of the slope
Answer:
The diameter is 0.022m.
Explanation:
The magnetic field 
at the center of the coil is given by
(1). 
where 
is the magnetic constant, 
is the current, 
number of coils, and 
is the diameter of the coil.
Now, if we call 
the length of the wire, then it must be true that
<em>(this says </em><em> coil circumferences (</em>
<em>) fit into </em><em> )</em>
putting this into equation (1) we get:
solve for 
putting in the numerical values
we get:
Answer:
0
Explanation:
the block is being pulled at a constant velocity meaning it has no acceleration. the rule is fnet=mass x acceleration so if theres no acceleration there is no force net!
Answer:
-0.056 is the deceleration
