Using this scale, a magnitude 5 earthquake would result in ten times the level of ground shaking as a magnitude 4 earthquake (and ...

Rainfall intensity is calculated as millimeters per hour over a given duration. Since the heaviest rainfalls are usually quite short in length, the average time frame used for the calculation is 5 minutes.Find the heart rate reserve (HRR); HRR = MHR – RHR. Calculate high and low THR by plugging in a percentage range and then adding in the RHR. In this example, 60 and 80% are being used. THRlow = HRR x .60 + RHR. THRhigh = HRR x .80 + RHR. The resulting low and high THR numbers represent the range, or target intensity.Another important and easily measured factor is sound intensity, or volume. We measure sound intensity (also referred to as sound power or sound pressure) in units called decibels. Decibels (dB) are named in honor of Alexander Graham Bell, the inventor of both the telephone and the audiometer. An audiometer is a device that measures how well a ...lm = 3cd*2*π* (1-cos (70°/2)) lm ≈ 3,39. So it is true, if we increase the apex angle of a lamp while keeping the luminous intensity the same, the lumen output will also increase. We can also test this the other way around, lets keep the apex angle at 70°, but reduce the light intensity a half, from 3cd to 1,5cd.
