Explanation:
The given data is as follows.
Area (A) = 0.7 
.
Electric field between the plates, (E) = 55 N/C
Since, electric field is related to surface charge density as follows.
Also, E = 
or, 
Therefore, charge will be calculated as follows.
Q = 
= 
= 
= 341 pC
Thus, we can conclude that magnitude of the charge on each plate is 341 pC.
The solution to the problem is as follows:
Normal force is m*g plus 240 N*sin30.
<span>30 kg*9.8 m/s^2 + 240 N*sin30 = 414 N

Answer:
We know the information about atomic size, energy, electronic configuration etc. of atom from the periodic table.
Explanation:
- Periodic table is the arrangement of elements that are arranged according to their properties and electronic configuration.
- In periodic table, on furthest right side of the periodic table, noble gases like He, Ne, Ar etc are arranged.
- The atomic number of element increases while moving from left towards right in the periodic table.
- The metallic character of element decreases as we proceed the table towards right.
- They readily accept electron to fill the valence shell hence becoming more metallic in character.
