Answer:Relative humidity is a better
measure
Explanation:
Why? Because relative humidity measures the amount of moisture in the air compared to the current temperature of the air and what it can hold at that point. While few point merely measures the temperature of the air at which it reaches dew point and dew falls. . The basic conditions for a thunderstorm are moisture, unstable air and lift. It would be easier to read off moisture level in the air since relative humidity at 90 to 100 means it will rain more certainly than it will with dew point which may only mean that dew will fall.
Answer:
After three half-lives, it is 7:1
Explanation:
- The rate at which the decay of the radioactive isotope is said to be half-life and is represented as the half-life of the atoms and the matter to disintegrate itself.
- The two radioactive isotopes are K 40 and Ar 40. After the K-Ar dating, they contain minerals such as the clay mica and the temphra minerals and Half-life of the K 40 is 1.3 more than 100,000 years i.e 10x9 years for Ar 40.
- <u>Thus the K 40 has to divide as three half-lives have passed if the ratio of argon to potassium atoms is 7:1. At the end of one half-life, the ratio of the number of argon to potassium atoms is 1:1. and two half lives its 3:1 thus after the third half-life it becomes as 7:1.</u>
After doing a lot of research on the answers to questions 40-42 on the Regents exam and studying the map you posted, the answer can be easily figured out.
It will take approximately 3 hours for the apparent position of the sun to change from point A on the map to point B on the map.
The correct answer choice will be number 3, 3 hours.
Answer:
<u>Warm water is melting the Arctic Sea ice</u>.
The research team is led by Son Nghiem.
<u>The sudden flow of warm waters into the sea are rapidly warming the ocean's surface.</u>
A paper describing the study can be found online.
The journal is called Geophysical Research Letters.
Explanation:
those are the correct answers
Answer:
- $60
- 103 sales
Explanation:
1. The sweater was originally priced at $80 and then got marked down by 25%. The new price is;
= 80 * ( 1 - 25%)
= 80 * 0.75
= $60
2. Terry earns a basic salary of $250 plus $5 per sale. To make a total of $765, from sales commission alone Terry must make;
= 765 - 250
= $515
Sales to make = 515/5
= 103 sales
