Missing question:
a) benzene, Kf = 5.12°C/<span>m.
</span><span>b) ethanol, Kf = 1.99°C/<span>m.
c) </span></span><span>chloroform, Kf = 4.70°C/<span>m.
d) </span></span><span>carbon tetrachloride, Kf = 29.9°C/<span>m
e) </span></span>diethyl ether, Kf = 1.79°C/m.
Answer is: d) carbon tetrachloride, Kf = 29.9°C/m.
b(solution) = 0,2 m.
ΔT = Kf · b(solution).
Because molality (b) is constant, greatest freezing point lowering is solution with highest Kf (<span>the freezing point depression constant).</span>

A disk of radius 2.0 cm has a surface charge density of 6.3 μC/m2 on its upper face. What is the magnitude of the electric field
maksim [4K]

Answer:

the electric field at Z = 12 cm is E =   9.68 × 10³ N/C = 9.68 kN/C

Explanation:

Given: radius of disk, R = 2.0 cm = 2 × 10⁻² cm, surface charge density,σ = 6.3 μC/m² = 6.3 × 10⁻⁶ C/m², distance on central axis, z = 12 cm = 12 × 10⁻² cm.

The electric field, E at a point on the central axis of a charged disk is given by E = σ/ε₀(1 - \frac{z}{\sqrt{z^{2} + R^{2} }  })

Substituting the values into the equation, it becomes

E = σ/ε₀(1 - \frac{z}{\sqrt{z^{2} + R^{2} }  }) = 6.3 × 10⁻⁶/8.854 × 10⁻¹²(1 - \frac{0.12}{\sqrt{0.12^{2} + 0.02^{2} } }) = 7.12 × 10⁵(1 - \frac{0.12}{0.1216}) = 7.12 × 10⁵(1 - 0.9864) = 7.12 × 10⁵ × 0.0136 = 0.0968 × 10⁵ = 9.68 × 10³ N/C = 9.68 kN/C

Therefore, the electric field at Z = 12 cm is E =   9.68 × 10³ N/C = 9.68 kN/C
