Answer:
525,000J
Explanation:
Power = work/time
Given
Power = 350 watts
Time = 25 mins = 25 x 60 = 1500 secs
Therefore
350 = work/1500
Cross multiply
Work = 350 x 1500
Work = 525,000J

Which wavelengths of light drive the highest rates of photosynthesis?
400-450 nm and 670-680 nm
Light in the violet-blue and red portions of the spectrum is most effective in driving photosynthesis
photosynthesis is the process through which green plant manufacture there food through sunlight, they synthesize nutrient in the this process through chlorophyll thereby releasing oxygen as a bye-product. a spectrum contains 7 colours combined . the violet-blue and red portions of the spectrum is most effective
The sum of angles in a regular pentagon is
180*(5 - 2) = 540°
Each internal angle is 540/5 = 108°.
Each vertex creates a line of symmetry to the midpoint of the opposite side,
as shown in the figure.
Answer: 5 lines of symmetry.
