Answer:

(a) 0.0666 A (B) 0.0666 A

Explanation:

(A) We have given emf E_0=14 V

The resistance of the circuit = 210 ohm

Emf frequency = 100 Hz there is no use of frequency in case of resistive load as it is independent on the frequency

According to ohm's law E_0=iR

So 14=i\times 210

i=\frac{14}{210}=0.0666A

(B) We have given emf E_0=14 V

The resistance of the circuit = 210 ohm

Emf frequency = 100 KHz there is no use of frequency in case of resistive load as it is independent on the frequency

According to ohm's law E_0=iR

So 14=i\times 210

i=\frac{14}{210}=0.0666A

Note : As the resistive load is independent on the frequency so resistance will be same and so current will also be same in both case

part 1

mass = ρ x V

mass = 1739 kg/m³ x 3.8 km³ = 6608.2 kg

PE (potential energy)= mgh

PE = 6608.2 kg x 9.81 x 403

PE = 2.61 x 10⁷ J

part 2

megaton of TNT (Mt) =4.2 x 10¹⁵ J

convert PE to Mt:

2.61 x 10⁷ J : 4.2 x 10¹⁵ J = 6.21 x 10⁻⁹ Mt
