Answer:
E = 2.85×10⁻¹⁹ J
Explanation:
Given data:
Wavelength of light = 700 nm
Frequency of light = 4.3×10¹⁴ s⁻¹
What is the energy of light = ?
Solution:
Formula:
E = h × f
h = plancks constant = 6.63×10⁻³⁴ Js
by putting values,
E = 6.63×10⁻³⁴ Js × 4.3×10¹⁴ s⁻¹
E = 28.5×10⁻²⁰ J
E = 2.85×10⁻¹⁹ J
Answer:
Plantae. Plants are multicellular and most don't move, although gametes of some plants move using cilia or flagella. Organelles including nucleus, chloroplasts are present, and cell walls are present. Nutrients are acquired by photosynthesis (they all require sunlight).
