Answer:
The resistance of the inductor at resonance is 258.76 ohms.
Explanation:
Given;
resistance of the resistor, R = 305 ohm
capacitance of the capacitor, C = 1.1 μF = 1.1 x 10⁻⁶ F
inductance of the inductor, L = 42 mH = 42 x 10⁻³ H = 0.042 H
At resonance the inductive reactance is equal to capacitive reactance.

Where;
F₀ is the resonance frequency

The inductive reactance is given by;

Therefore, the resistance of the inductor at resonance is 258.76 ohms.

Answer:
19372.29 N
Explanation:
Kinetic Energy of the man = Work done by the average resistive force of water.
mg(H+d) = F×d............................ Equation 1
where, m = mass of the woman, H = Height of the platform, d = depth of water reached, F = average resistive force exerted by water.
make F the subject of the equation,
F = mg(H+d)/d...................... Equation 2
Given: m = 65.0 kg, H = 10 m, d = 3.4 m, g = 9.8 m/s²
Substitute into equation 2
F = 65(9.8)(100+3.4)/3.4
F = 19372.29 N
