In the SI system of units, the standard unit of acceleration is 1 metre per second squared<span> (abbreviated as m/s2). Other units include the gal (sometimes known as a galileo, in either case with symbol Gal), which equals 1 centimetre per second squared, and the g (gn), equal to 9.80665 m/s2.</span>
A magnitude-5.0 earthquake releases about <u>32</u> times more energy than a 4.0 magnitude earthquake.
Explanation:
The characteristics of an earthquake are mostly measured through its magnitude and intensity.
A earthquake will generate seismic energy waves which will spread outwardly on the earth's surface in all directions.
The magnitude of an earthquake is the quantitative measure of the amount of energy released during a seismic activity or an earthquake.
The intensity of an earthquake is a descriptive measure of the severity or the strength of the earthquake based on the impact it has done on the earth’s surface, human population, and other man-made structures on the earth and the potential danger.
The magnitude measured using a seismograph is expressed as a whole number or a decimal fraction like 5.7, 4.5 etc. The severity of the magnitude is compared against the standard Richter’s Scale.
The intensity is denoted in Roman numerals and compared against various scales like Mercalli or Rossi-Forel Scales.
Based on the logarithmic application of the scale, each whole number increase in an earthquake’s magnitude depicts a ten-fold increase in severity of the amplitude of the earthquake as measured on the seismogram and denotes about 32 times increased energy release

The answer is c. Deciduous trees lose their leaves to prevent nutrient and water loss.
Losing leaves is a trees' strategy to survive cold winters. It is known that trees primarily lose water through leaves. In the winter, there is no enough water to replace that lost water. If the trees were not to throw away their leaves, they will soon dry out. Also, before falling the leaves begin, reabsorb all nutrients from the leaves and store it for the cold winter. Thus, losing leaves is important to prevent both nutrient and water loss during the winter.
