If you try to fit the edges of both continents than they should somewhat fit each other like puzzle pieces
I don’t see any answer choice but the best way is asking questions about the natural phenomenon, making hypothesis, and predicting the consequences in the hypothesis.
Given that ;
Energy (work ) Produced by bulb =20 KJ = 20000 J
Input power = 15 KW
Output power given by the bulb = Rate of doing work
= Work ÷ time
= 20000 ÷ 1800 <em>(since 1 min = 60 seconds)</em>
= 11.11 W
Noe, efficiency is the ratio of output power to input power
η = output power ÷ input power
= 11.11 ÷ 15
= 0.74
= 74%
<em>Efficiency of light bulb is 74%</em>

<span>The earth gets most of its energy from the sun. The answer is letter B. This
is because most of the living organisms on earth need sunlight to perform
activities that would balance the ecosystem. Sunlight is the reason for the
climate system on earth, the production of food through cellular respiration
and many more.</span>
