(a) The reactance of the inductor is 25.46 ohms.
(b) The expression for the current through the inductor is I(t) = (6.32 A) sin(134t)
<h3>Ractance of the inductor</h3>
The reactance of the inductor is calculated as follows;
XL = ωL
where;
- ω is angular frequency
- L is 190 mH
v(t) = (161 V) sin(134t)
v(t) = V sin(ωt)
The reactance of the inductor is calculated as follows;
XL = (134) x (190 x 10⁻³)
XL = 25.46 ohms
<h3>Peak current in the circuit</h3>
I₀ = V₀/XL
I₀ = (161) / (25.46)
I₀ = 6.32 A
<h3>Expression for the current through the inductor</h3>
I(t) = (6.32 A) sin(134t)

Answer:
3. Large butterfly in flight, flying through the air?
Explanation:
Momentum is simply defined as the quantity of motion a body possess. It is mathematically given as;
Momentum = mass x velocity
The larger the mass, the larger the momentum and also the velocity
Since the large butterfly is in flight, it has the largest velocity.
A sleeping bear and resting caterpillar have no momentum because their velocity is 0
Sodium (Na) is very reactive because it does not have a full valence shell.
