Explanation:
modern quantum mechanics explains these periodic trends in properties in terms of electron shells. the filling of each shell corresponds to a row in the table
Answer:
#Where is in meters and in seconds.
Explanation:
Given that :
From we have:
From we have that:
Now,given that the initial value problem is given by:
Hence,the position of u at time t is given by
, in meters, in seconds.
Answer:
5.648 N/C
Explanation:
Given:
q₁ = 60 pC/m² = 60 × 10⁻¹² C/m²
q₂ = -80 pC/m² = - 80 × 10⁻¹² C/m²
Now,
Electric field is given as:
E =
ε₀ = Permittivity of Free Space
thus, due to charge q₁
E₁ =
or
E₁ = 3.389 N/C
and, due to charge q₂
E₂ =
or
E₂ = 4.519 N/C
Now,
The resultant electric field =
or
The resultant electric field =
or
The resultant electric field =
or
The resultant electric field = 5.648 N/C
