Richter Scale and Mercalli Scale are the parts of different tools used by experts to ascertain the level of intensity, magnitude and the strength of a natural disaster like earthquake. They can also be used to give a kind of forecast about the possible occurrence of natural disasters like earth tremor or earthquake so as to actively and adequately create various measures that will counter the effects of the possible occurrence. However, there are some differences between Richter scale and Mercalli scale.
Richter scale is made in form of a barometer to measure the magnitude of the earthquake in the affected area. While, Mercalli scale is used to measure the intensity of the seismic activity. Richter scale can be regarded as the older instrument out of the two. Mercalli scale is just a newer version of Richter which has been subjected to a lot of modifications. Richter scale is widely used and experts prefer it to Mercalli scale.
Scales and balances are machines that are used to weigh objects. These terms are often confused with one another, and they are used interchangeably. However, the process by which this is done is different from one another. Scales work to measure weight through the use of a tension force of constraint. The scale is used to measure the weight of objects.
Scales are sensitive to environmental factors; this makes reading inaccurate. Balance is used to measure the mass of objects. It works by comparing the unknown mass with a known mass. It is not affected by the gravitational force. The reading of a balance remains the same irrespective of the location.
The correct answer is option C
On the map,
½ inches = 12mi
And the distance from Gainesville to Columbus is 4 inches.
Then, the actual distance from Gainesville to Columbus will be:
4 inches = ?
If ½ inches = 12
4 inches = 8 (1/2 inches)
8 12 = 96
Therefore, the actual distance between Gainesville to Columbus is 96mi.
The ABEC is known to be a rating system. If you are a skater or you are familiar with using the skateboard, then you know that these are two different things. ABEC means Annular Bearings Engineerings Committee. The higher the ABEC values, the higher the bearing of the skateboard overall. The ABEC will mean that you can get the strictest tolerance and will make sure that everything will be correctly made.
ABEC 5 bearings are usually chosen to upgrade the stock bearings of the skateboard. ABEC 7 is known to be more high-class and will sometimes be used by professionals. ABEC 5 is known to be cheaper than ABEC 7.
I sort of thought the "how" was not important. The "why" seemsok to clarify why you are really doing something.
