Question

A burner consumes 110kj of energy in 55 seconds what is its power in kW

Answer 1

Answer:

power = 2KJ/S

Step-by-step explanation:

power = work done/ time

power = 110/55

power = 2KJ/S

Answer 2

The power is 2kW

Explanation: Power and energy are frequently seen as synonyms. Although they are not the same type of physical quantities, energy and power are believed to be closely related. Despite the fact that they have been utilised in daily life, there is a fine but noticeable difference between them.

Running, jumping, and other physical actions all require energy, however, the definition of power is the speed at which the work is done or the energy is delivered. Joules, ergs, and calories are the terms used to describe energy. Watts, often known as ergs per second or even joules per second, are the units used to measure power.

Given, that a burner consumes 110kJ of energy in 55 seconds

We know Power P =$\frac{Energy}{Time}$

Energy $E=110kJ=110\times 10^3J$

Time $t=55s$

$\Rightarrow P=\frac{110\times 10^3}{55}\\\\\Rightarrow P= 2\times 10^3W\\\therefore P=2\ kW$
