1. <span>the low pressure is moving slower than expected.
This make the meteorologist receive premature data which make them fail to interpret the data correctly and make the wronf prediction.
2. Sudden change in wind direction, which transfer the natural occurence into other region than where it initially predicted
3. We still haven't developed the methodology to 100% predict natural occurence</span>
Initially there were 10 bulbs of 60 Watt power
So total power of all bulbs = 60 * 10 = 600 W
now each bulb used for 4 hours daily
so total energy consumed daily
now we have total power consumed in 1 year
cost of electricity = 10 cents/ kWh
so total cost of energy for one year
Now if all 60 Watt bulbs are replaced by 30 Watt bulbs
So total power of all bulbs = 30 * 10 = 300 W
now each bulb used for 4 hours daily
so total energy consumed daily
now we have total power consumed in 1 year
cost of electricity = 10 cents/ kWh
so total cost of energy for one year
total money saved in 1 year
A set of data has a mean of 12 and a standard deviation of 3. A data point of the set has a z-score of 1.3. What does a z-score of 1.3 mean?
The data point is 1.3 standard deviations away from 3
The data point is 1.3 standard deviations away from 12.
The data point is 3 standard deviations away from 1.3.
The data point is 3 standard deviations away from 12.
its B
Ans: Radiocarbon dating uses carbon isotopes.
Radiocarbon dating relies on the carbon isotopes carbon-14 and carbon-12. Scientists are looking for the ratio of those two isotopes in a sample. Most carbon on Earth exists as the very stable isotope carbon-12, with a very small amount as carbon-13.
Answer: B
To measure a lower-pitched sound wave, you would
measure fewer compressions per second. Pitch <span>relates to frequency by measuring how many times a second the
particles vibrate. Therefore, the lower-pitched sounds, the fewer compression waves or sound waves are produce because low-frequency
sounds have greater distance between each wave.</span>
Moreover,
the frequency of a wave is measured as the number of complete
back-and-forth vibrations of a particle of the medium per unit of time. <span>The universal unit for frequency used is
the Hertz (abbreviated Hz), where 1
Hertz = 1 vibration/second. </span>
