Answer:
2.12 × 10⁻⁷ C
Explanation:
Given:
Charge on the glass sphere, Q = 10.9 nC = 10.9 × 10⁻⁹ C
Distance between the glass and the metal sphere, r = 4.0 cm = 0.04 m
Force experienced by the metal sphere, F = 0.0130 N
let the charge on the metal sphere be 'q'
Now,
the force due to a charge on the other charge is given as:
where,
k is the coulomb's constant = 9 × 10⁹ N.m²/C²
on substituting the values in the formula, we get
or
q = 2.12 × 10⁻⁷ C
Answer:
Engineering
Explanation:
STEM mainly incorporate knowledge from four disciplines which are:

Answer:
Stress corrosion cracking
Explanation:
This occurs when susceptible materials subjected to an environment that causes cracking effect by the production of folds and tensile stress. This also depends upon the nature of the corrosive environment.
Factors like high-temperature water, along with Carbonization and chlorination, static stress, and material properties.
Answer:
Equilibrium Concentration = 0.105mg/kg
Explanation:
Let initial concentration be C₀
S(aq) at initial = C₀ , S(s) at initial = 0
S(aq) at equilibrium = C₀ - Xe , S(s) at equilibrium = Xe
Xe = 1312.5 mg/kg
At equilibriuim Kd = [S(s)]/[S(aq)]
12500 = 1312.5/(C₀ - 1312.5)
C₀ = 1312.605 mg/kg
Equilibrium Concentration = 1312.605 - 1312.5 = 0.105mg/kg
