Answer:
The electric flux going through the sphere is 
Explanation:
Given

Required
Calculate the electric flux
Electric flux can be computed using the formula;
Ф = q/ε
Where ε stands for the electric constant permittivity
ε 
Substituting ε
and
; the formula simplifies to
Ф = 
Ф = 
Ф = 
Ф = 
Ф = 
Ф = 
Ф = 
Ф = 
Thus, the electric flux through the sphere is 
The male skater reaches a velocity of 13.71 m/s. According to the principle of conservation of momentum, m1u1 = (m1 + m2)u2, where m1 signifies the mass of the male skater at 78.2 kg, m2 is the mass of the female partner at 48.5 kg, u1 is the male skater's resulting velocity from the push, and u2 is the velocity imparted to the female skater, which was 8.46 m/s. Through the formula, we find u1 = [(78.2 + 48.5) × 8.46] ÷ 78.2, which calculates to 1071.882 ÷ 78.2 resulting in u1 = 13.71 m/s.
Answer:
The area that remains is 4.201 m²
Explanation:
Provided that
AB=D= 4 m (R=2 m)
The area of the half-circle AB is

A=2π
The area of the smaller half-circle is
a=5π/6 + 2√3/4 m²
a=5π/6 + √3/2 m²
<pThus, the remaining area = A - a
= 2π - (5π/6 + √3/2) m²
The remaining area is expressed as 2π - (5π/6 + √3/2) m²
