2 a/s

(c) find the current 0.250 s after the circuit is closed.
3 a

(d) find the final steady-state current.
4 a

(a). The initial rate is 2.60 A/s.

(b). The rate of current increases is 0.8658 A/s.

(c). The current is 0.435 A.

(d). The final steady-state current is 0.75 A.

Explanation:

Given that,

Inductance = 2.30 H

Resistance = 8.00 Ω

Voltage = 6.00 V

(a). We need to calculate the initial rate of increase of current in the circuit.

Using formula of initial rate

Put the value into the formula

The initial rate is 2.60 A/s.

(b). We need to calculate the rate of increase of current at the instant when the current is 0.500

Using formula of rate of increase of current

....(I)

Where,

Using formula of current

The rate of current increases is

Put the value in the equation (I)

The rate of current increases is 0.8658 A/s.

(c). We need to calculate the current

Using formula of current

Put the value into the formula

The current is 0.435 A.

(d). We need to calculate the final steady-state current

Using formula of steady state

The final steady-state current is 0.75 A.

Hence, This is the required solution.

what was the answer?

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
