Earthquake measuring 4.5 is 10 times more powerful than earthquake measuring 3.5 on Richter scale.
Step-by-step explanation:
Earthquake refers to the violent shaking of the Earth crust in response to its extremely dynamic interior. Sometimes the rocks are loaded or stressed beyond its elastic limit, following which it rebounds thus emitting a wave(seismic), which is received by us as seismic waves.
The energy released during an earthquake is measured in Richter scales (named after Charles Richter). While 1 is the lower limit, there is no such upper limit. However, earthquakes above 7 are considered fragile for human existence. It is a logarithmic scale meaning successive numbers of the scale by a factor of 10.
Thus, an earthquake measuring 4.5 would be around 10 times more powerful than an earthquake measuring 3.5 following logarithmic scale.
It would most likely equal to 6. Hope this helped.

Answer:
11/22 = 1/2
Step-by-step explanation:
There are 22 students in Ms. Cathies, and 11 girls and 11 boys. The chances of her picking me are 11 out of 22. So the answer is 1/2
