Answer:
They get it from the air and soil. They also take energy from the sun.
Explanation:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil.
Answer:
1/f = 1/i + 1/o thin lens equation
1/i = 1/f - 1/o
i = o * f / ( o - f) = 50 * (-20) / (50 - (-20)) = -14.3 cm
The final image is erect and 14.3 cm behind the curved surface
M = -o / i = 14.3 / 50 = .29 magnificaton of object
S = .29 * 25 cm = 7.1 cm appearance of bird in mirror (height)

To Find :
(a) What is the time taken to complete one lap of the circular track.
(b) What is the time taken for 10 laps.
Solution :
Circumference of circular track,
a) Time taken to complete one lap is :
b) Time taken to complete 10 laps is :
Hence, this is the required solution.
Explanation:
