NeX [460]3 years ago
4 0

Answer:

<em>The reactance is 80 Ω</em>

<em></em>

Explanation:

Inductance H = 2 H

voltage v = 10 V

angular speed ω = 40 rad/s

The reactance of an inductive ac circuit  X_{L} = ωL

X_{L} = 40 x 2 =<em> 80 Ω</em>

<em></em>

The current in the circuit is = V/X_{L} = 10/8 = 1.25 A

What causes objects to move or stay still?<br> Claim <br><br> Reasoning:<br><br> Evidence:
kari74 [83]

Answer:

For an object to move, there must be a force. A force is a push or pull that causes an object to move, change direction, change speed, or stop. Without a force, an object that is moving will continue to move and an object at rest will remain at rest.

Part B Write the balanced chemical equation for the neutralization reaction that occurs when an aqueous solution of hydrobromic
Doss [256]

Answer:

HBr(aq) + LiOH(aq) → LiBr(aq) + H2O(l)

Explanation:

A neutralization reaction is a process in which an acid, aqeous HBr reacts completely with an appropriate amount of base, aqueous LiOH to produce salt, aqueous LiBr and water, liquid H2O only.

HBr(aq) + LiOH(aq) → LiBr(aq) + H2O(l)

Acid + base → Salt + Water.

During this reaction, the hydrogen ion, H+, from the HBr is neutralized by the hydroxide ion, OH-, from the LiOH to form the water molecule, H2O.

Thus, it is called a neutralization reaction.
