Answer:
10 km
Explanation:
1 km = 1000 m
1 m = 1× 10 -³
There for
10,000 m = 10,000×1× 10 -³
= 10 km
Answer;
C. if water plants take in co2, then the solution will turn from yellow to blue.
Explanation;
-Bromothymol blue is a pH indicator that is mostly used in applications that require measuring substances that would have a relatively neutral pH. A common use is for measuring the presence of carbonic acid in a liquid or dissolved carbon dioxide.
-The indicator changes color over a pH range from 6.0 (yellow) to 7.6 (blue). It is a good indicator of dissolved carbon dioxide (CO2) and other weakly acidic solutions.
-Low levels of carbon dioxide or acid in solution with bromothymol blue indicator will appear blue. As the level of carbon dioxide or acid increases, the solution will gradually take on a yellow tint.
Answer:
Photovoltaic energy is the conversion of sunlight into electricity. A photovoltaic cell, commonly called a solar cell or PV, is the technology used to convert solar energy directly into electrical power. A photovoltaic cell is a non mechanical device usually made from silicon alloys.
Explanation:
ANSWER
EXPLANATION
Parameters given:
Mass of the student, M = 70 kg
Mass of the textbook, m = 1 kg
Distance, r = 1 m
To find the gravitational force acting between the student and the textbook, apply the formula for gravitational force:
where G = gravitational constant
Therefore, the gravitational force acting between the student and the textbook is:
That is the answer.
Hey there Donnell!
The reason to why light refract when it encounters the glass in a lens would be because it slows down, which causes it to bend, this would be the reason why <span> light refract when it encounters the glass in a lens.
I hope this helps you!</span>
