I believe it is C. Increase the temperature of coal
<span>Tides do place a drag on the earth's rotation, but gradually. This energy lost from the earth's rotation is picked up by the moon's orbit around the earth. The moon is receding from the earth. So, in answering your question, the length of the day has been increasing. Without getting into the arduous math involved, in the very distant future the moon will have reached its max distance and the earth's rotation will be in step with the moon's orbit.</span>
<span>The volume of water that moves past a point on a river in a given time is called the river’s DISCHARGE or FLOW RATE. The flow rate is used to measure and study bodies of water to better understand how they work. It is useful in areas such as wastewater treatment. Water flow or velocity typically increases as the the depth or hydraulic radius of the river increases.</span>
Mmm, you can work this one out in your head by reversing it.
<span>12.5 = 50g/4 </span>
<span>1/4 = 1/2 * 1/2 </span>
<span>thus in 14.4 seconds there have been 2 times the half life. 14.4/2 = 7.2 </span>
<span>the half life is 7.2 seconds.</span>
