<h3>What is a parallel circuit?</h3>

A parallel circuit is a circuit in which the components are connected to a common junction. This implies that if one bulb goes out in a parallel connection, all the bulbs will go out.

As such, Jasmine need to correct the error by switching the headings on the columns adding the title parallel circuits.

The temperature of a heat engine is 500 K. Some of the heat generated by the engine flows to the surroundings, which are
Naddik [55]

Answer:

The efficiency of the engine is 75%  under given conditions.

<u>Explanation: </u>

<em>Efficiency is defined as the ratio of work done by the engine to the total heat supplied to a heat engine</em>. We know work done by the heat engine be difference between total heat supplied \left(Q_{h}\right) by total heat utilized \left(Q_{c}\right). We can derive formula for efficiency by considering the above factors, \text { efficiency }=\frac{\text { work done }}{\text { heat suplied }}=\frac{Q_{h}-Q_{c}}{Q_{h}}=1-\frac{Q_{c}}{Q_{h}}=1-\frac{T_{1}}{T_{2}} \therefore \text { efficiency }=1-\frac{T_{1}}{T_{2}}  

Now consider a heat engine is at a temperature of 500K and the heat produced by the engine released to the surroundings at a temperature of 125K. The efficiency is calculated by using the above formula, \text { efficiency }=1-\frac{T_{1}}{T_{2}}=1-\frac{125}{500}=1-0.25=0.75

∴ Efficiency of the engine is 75%
